First Trip to Cambodia: Documents, Money and Safety

Prepared by the NovAsia Editorial Team

A first trip to Cambodia is much easier when four practical questions are settled before departure: which visa you will use, where you will enter the country, how you will pay, and what your medical insurance actually covers. Most other things—a local SIM card, airport transfer, Angkor tickets and everyday transport—can be arranged after arrival.

A common mistake is to prepare for Cambodia as though it were simply another standard Southeast Asian holiday destination. Cambodia uses both riel and US dollars in everyday life, Phnom Penh’s new airport uses the code KTI, Cambodia e-Arrival does not replace a visa, and an overland route from Thailand cannot be assumed to be available in 2026. Once these details are checked, the country is generally straightforward to navigate.

What to check before buying a ticket

Start with the route of entry rather than the hotel. Requirements depend on nationality, passport type, purpose of travel and border crossing.

At a minimum, confirm that:

• your passport will remain valid for at least six months from the date of entry;
• it has at least one blank page;
• you have the correct visa or a confirmed visa exemption;
• your chosen airport or border checkpoint accepts that type of visa;
• your return or onward journey is realistic on the planned dates.

Cambodian consular guidance for tourist visas normally requires at least six months of passport validity and a blank page. Airlines may check these documents before boarding, so relying on an explanation at immigration is a poor strategy.

Business meetings, property viewings and market research do not automatically make a tourist visit unlawful. However, paid work, local employment and long-term residence require a separate basis. The declared purpose of the trip should match what you actually plan to do.

Tourist eVisa: the simplest option for many first-time visitors

Cambodia’s official eVisa portal lists the following standard conditions for a Type T tourist visa:

The most common misunderstanding is the difference between visa validity and permitted stay. A visa valid for three months does not allow three months in Cambodia. It gives you a three-month window in which to make the single entry, after which the authorised period of stay begins.

Apply only through the official government website. Copycat sites may charge additional service fees, claim to offer unnecessary “priority” processing or collect more personal information than the official application requires.

Keep the approval in three forms: a PDF on your phone, a cloud copy and a printed copy. Even when the electronic record is visible to immigration, having your own copy simplifies conversations with airline staff and border officers.

Visa on arrival and visa-free entry depend on your passport

Cambodia offers visa on arrival to many travellers, while nationals of some countries can enter without a visa for a limited period. There is no universal rule for every passport.

Check the official requirements for your nationality before travelling. The airline and any transit country may also apply stricter documentary checks than Cambodia’s minimum entry rules.

Visa on arrival can be convenient, but it adds another process after a long flight. For a first independent trip, an approved eVisa is often more predictable because you know before boarding that your application has been reviewed.

If you plan to enter overland, confirm that the specific checkpoint accepts the eVisa. An old map showing a border crossing does not prove that the crossing is currently open or that it accepts every visa format.

Cambodia e-Arrival is not a visa

Cambodia e-Arrival is a separate electronic process combining immigration, health and customs declarations. The system also includes an electronic visa-on-arrival function for eligible travellers, which is one reason the terminology can be confusing.

Submitting the e-Arrival form itself is free. Official guidance recommends completing it within seven days before arrival, although it may also be possible to do so at the airport.

Save the QR code or confirmation and carefully check:

• your name exactly as shown in the passport;
• passport number;
• flight number;
• port of entry;
• first accommodation address;
• visa details;
• customs declaration.

The e-Arrival form does not extend your stay and does not replace any visa your passport requires. They are separate procedures even when accessed through the same digital system.

There is usually no reason to pay an intermediary merely to complete the free form unless you knowingly choose a broader assistance service.

Phnom Penh’s new airport uses KTI, not PNH

Since 9 September 2025, scheduled international and domestic commercial flights serving Phnom Penh have operated through Techo International Airport. The new airport replaced the former Phnom Penh International Airport for commercial passenger operations and uses the code KTI.

This matters when booking flights, arranging airport transfers and completing arrival forms. Old articles, saved templates and outdated travel itineraries may still display PNH.

Techo International Airport is approximately 20 kilometres south of Phnom Penh. Travel time depends on traffic and your exact destination. BKK1, Riverside and the southern districts all require different routes.

The airport lists licensed taxis, Grab, PassApp, WowNow, an Airport Express Bus and car rental. For a first arrival with luggage, a car booked through an app or a confirmed hotel transfer is usually the least stressful option.

Airport Express Bus

The Airport Express Bus operates daily between the airport and Kouch Kanong Circle Bus Station, with published hours from 5:30 a.m. to 11:30 p.m.

The route uses Monivong Boulevard and Hun Sen Boulevard and includes stops near Canadia Garden by the Royal Cambodian Railways, the Royal University of Law and Economics and AEON Mall Mean Chey.

The bus is suitable for travellers with light luggage who understand how they will reach their accommodation from the final stop. It is less convenient after a late flight, with children or when the hotel is far from the route.

Check the current timetable on the day of arrival. A published operating window does not guarantee a short wait or predictable traffic conditions.

Do not plan an overland route through Thailand without current confirmation

As at 25 June 2026, land crossings between Cambodia and Thailand remain closed following armed conflict in the border area.

Government travel advisories also warn against travel close to parts of the Cambodia–Thailand border because of military activity, mines and closed attractions.

This does not mean that ordinary life in Phnom Penh or central Siem Reap resembles a conflict zone. It does mean that the old Bangkok–Poipet–Siem Reap route, and trips towards sensitive border temples, should not be planned using pre-conflict information.

Air connections and transit rules through Thailand should be confirmed with the airline. Do not treat an overland crossing as a backup option unless it has been officially confirmed open on the date of travel.

How long to allow for a first trip

A few days are enough to see Phnom Penh, but not enough to understand Cambodia. A first itinerary combining Phnom Penh and Angkor generally needs at least one week without an exhausting schedule.

A workable eight- to ten-day structure could be:

This is not a compulsory itinerary. Someone evaluating relocation may spend five to seven days in Phnom Penh before adding Siem Reap. A traveller coming primarily for Angkor may reverse the balance.

Avoid trying to fit Phnom Penh, Siem Reap, the islands, Mondulkiri and several remote temples into one short trip. Cambodia looks compact on a map, but transfers, heat and early starts quickly create fatigue.

A scouting trip for relocation

A relocation visit should include ordinary life, not just attractions. Stay in a residential neighbourhood, test a possible commute in the morning, work a full day from the apartment, visit a supermarket and clinic, inspect streets after rain and view rental properties without paying a deposit.

Do not turn the entire week into a marathon of property viewings. Before you understand the city, one normal day in BKK, Toul Tom Poung or Toul Kork is more useful than ten similar condominium lobbies. The trip should end with a shortlist and better questions, not a forced reservation.

Travelling between Phnom Penh and Siem Reap

Domestic flights, intercity buses, minivans and private cars connect Phnom Penh and Siem Reap. Schedules and prices change, so check them for your exact travel date.

Flying saves road time but still involves airport transfers and baggage procedures. Overland transport is generally cheaper but takes a significant part of the day. Choose a company with an official office, a clear departure point and seat belts.

An overnight trip saves a hotel night but increases road risk and leaves you tired. Government travel advice recommends avoiding night travel outside the main cities where possible. Treat the transfer as a full part of the itinerary rather than scheduling Angkor immediately after arrival.

Angkor tickets: use official channels

Angkor Enterprise sells admission through its official website, mobile application, ticket office, kiosk and authorised guides.

As at 25 June 2026, the standard passes are:

Electronic tickets can be shown on a phone. Multi-day passes require a visitor photograph.

A three-day pass does not require three consecutive temple days. This is useful in hot weather because you can alternate temple visits with rest, museums or other activities.

Save the pass offline. Entry should not depend on mobile reception or access to your email account.

A random sponsored link does not offer an advantage over the official seller. When a guide arranges the ticket, ask to receive the official Angkor Pass.

What to wear at Angkor and other temples

Angkor is both an archaeological park and a sacred place. APSARA National Authority asks visitors to dress appropriately, respect monks and worshippers, avoid touching or climbing structures, refrain from littering and not give money to children.

In practical terms, shoulders and knees should be covered, especially in active religious spaces. Very short clothing or beachwear may result in refusal of access to some areas.

A sensible temple outfit includes:

• lightweight long trousers or a below-the-knee skirt;
• a T-shirt or shirt covering the shoulders;
• footwear suitable for steps;
• sun protection;
• drinking water;
• mosquito repellent;
• a light rain jacket in the wet season.

A loosely draped scarf is not always accepted as a substitute for appropriate clothing. Dress suitably from the start rather than relying on a decision at the entrance.

Avoid photographing people at close range while they are praying, and do not treat monks as decorative props. Ask before taking a personal photograph.

Money: riel, dollars and bank cards

The official currency is the Cambodian riel. US dollars remain widely used for larger transactions and in tourist areas, but this does not mean that every dollar note will be accepted.

Old, dirty, torn or marked notes may be refused. Tourism and financial authorities encourage greater use of riel and digital payments partly because damaged foreign notes are difficult to process.

A practical first-trip payment setup is:

• a modest amount of clean US dollars;
• riel for small purchases;
• a primary bank card;
• a backup card from another bank;
• emergency cash stored separately;
• bank notifications enabled.

Change from a dollar payment may be given in riel. It helps to understand the approximate exchange rate, although minor rounding is normal. For larger purchases, agree on the rate and final amount in advance.

Do not carry your entire budget in cash. Equally, do not rely on a single foreign card. A bank may decline a transaction, a terminal may fail and smaller sellers may accept only cash or KHQR.

KHQR is used extensively. For a longer stay, the Bakong Tourists App may be worth exploring, but cash and cards should remain available as backups.

Cash declaration threshold

Cambodia’s General Department of Customs and Excise states that foreign currency below the equivalent of $10,000 does not normally require a customs declaration when entering or leaving.

Amounts of $10,000 or more must be declared. When later exporting a substantial amount, evidence of the original declaration and additional permission may be required if the amount exceeds what was declared.

This is a reporting rule, not a blanket prohibition on carrying money. However, an ordinary tourist has little reason to transport large amounts of cash instead of using regulated banking channels. Money intended for a future property purchase should not be carried simply to avoid bank compliance checks.

ATMs and cards

ATMs are widely available in Phnom Penh and Siem Reap. Depending on the bank and machine, they may dispense US dollars, riel or both.

Before confirming a withdrawal, check the currency, fee, limit and any offered conversion rate. Dynamic currency conversion may be less favourable than your own bank’s rate. Use machines inside bank branches or shopping centres where possible, and do not carry your passport, main card and all your cash together.

SIM cards and mobile internet

A local SIM card is normally registered against your passport and valid immigration status. Buy it from an official operator outlet at the airport, shopping centre or in the city.

Before leaving the counter, confirm:

• the phone number;
• mobile data is working;
• package validity;
• included data allowance;
• how to top up;
• that registration is in your name.

An eSIM gives immediate connectivity after landing, while a local SIM is often more convenient for local calls and services. Keep your home-country number active if it receives banking verification messages.

Do not use open Wi-Fi for banking. Maps, tickets and ride-hailing applications should all have a mobile-data backup.

Getting around Phnom Penh

There is no need to rent a car or motorbike on a first trip. Grab, PassApp and conventional taxis cover most journeys. Tuk-tuks are convenient for short trips; cars are more comfortable for the airport, rain and luggage.

Set an exact map pin rather than relying only on a venue name. Large buildings may have several entrances, and the driver can otherwise end up on the opposite side of the block.

Walking is practical within some central areas, but pavements are inconsistent. Two places that appear close on a map may be separated by a difficult boulevard, parked vehicles and dense traffic.

Motorbike taxis can save time but involve greater risk. They should not be the default transport choice for someone unfamiliar with the city.

Why renting a motorbike immediately is a bad idea

Traffic in Cambodia requires adjustment. Cars, trucks, tuk-tuks, motorbikes, bicycles and pedestrians share the same space, often with informal lane behaviour.

Before renting, check whether your licence and International Driving Permit are recognised, whether the vehicle is properly registered, and what the insurance covers. Claims may be refused if you lack the correct authorisation or were not wearing an approved helmet. Experience on a quiet island does not prepare a rider for Phnom Penh traffic.

Weather and clothing

Cambodia is hot throughout the year. November to February is generally drier and somewhat cooler. March to May brings the most intense heat, while the wet season typically runs from around May to October.

The wet season does not mean constant rain. A day may remain sunny before a short, heavy downpour. The practical issue is delayed transport, sudden flooding on individual streets and wet luggage rather than continuous rainfall.

Useful items include:

• light, breathable clothing;
• a temple-appropriate outfit;
• hat and sun protection;
• mosquito repellent;
• compact rain jacket;
• quick-drying footwear;
• waterproof protection for documents and phone;
• a light layer for heavily air-conditioned spaces.

An ambitious itinerary is harder in April than it looks on a map. Angkor is best explored in morning blocks with breaks.

Medical preparation

Insurance should cover more than a routine doctor’s appointment. Look for hospitalisation, the activities you plan to undertake and medical evacuation. Private hospitals may require prior insurer approval or a deposit.

Discuss your route with a travel-medicine clinician. The CDC recommends routine immunisations, hepatitis A vaccination for unvaccinated travellers and typhoid vaccination for many visitors, particularly those travelling beyond major urban areas.

Dengue is a year-round risk, and Cambodia was included in the CDC’s global dengue travel notice in June 2026. Prevention depends mainly on avoiding mosquito bites.

Malaria risk is concentrated in rural and forested areas. The CDC describes transmission in Phnom Penh, Siem Reap city and the main Angkor Wat complex as absent or negligible. A forest or remote-area itinerary requires individual medical advice before travel.

A yellow fever vaccination certificate may be required when arriving from, or after substantial transit through, a country with yellow fever risk. This depends on your route, not on local yellow fever transmission in Cambodia.

This article is informational and does not replace advice from a doctor, insurer or immigration professional. Vaccinations, medication, visas and coverage must be checked for your nationality, health and exact itinerary.

Water, food and a basic travel kit

Use sealed bottled water at first and do not assume untreated tap water is suitable for drinking. Food safety depends more on turnover and preparation than on whether the seller operates indoors or on the street.

Street food is not automatically dangerous, and a restaurant is not automatically safe. Prefer places where food is cooked fresh, served hot and stored sensibly.

A basic travel kit may include:

• regular medication;
• a copy of prescriptions;
• doctor-approved pain and fever medicine;
• oral rehydration salts;
• plasters and antiseptic;
• mosquito repellent;
• sunscreen;
• enough medication for a flight delay.

Avoid carrying a random collection of antibiotics for self-treatment. Pharmacies are widely available, but important medication should travel in its original packaging.

After an animal bite or scratch, wash the wound thoroughly with soap and water and seek medical attention promptly. Do not handle dogs or monkeys for photographs.

Protecting your phone and bag

Snatch theft from motorbikes is one of the most characteristic risks in Phnom Penh. Government travel advice warns that bag straps may be cut and phones or bags grabbed from pedestrians and passengers in tuk-tuks.

Useful precautions include:

• do not hold a phone out over the road;
• keep bags away from the open side of a tuk-tuk;
• do not hang a bag on the back of a chair beside the street;
• leave the passport securely stored unless needed;
• carry a cross-body bag close to the centre of your body;
• avoid walking on an empty street at night while looking at a screen;
• keep document copies separately;
• enable remote phone locking and data deletion.

Do not hold onto a bag if doing so risks dragging you into traffic. Physical injury may be far more serious than the value of the belongings.

For navigation, stop beside a wall, inside a café or in a lobby rather than opening the map at the kerb.

Roads and intercity travel

Road safety is a more significant risk than most tourist scams. Vehicles, motorbikes and pedestrians often share limited space, while priority rules may differ from what you are used to.

For intercity travel, choose transport with seat belts and avoid a driver operating through the night without relief. An overloaded minivan does not become safe because it has a good price rating.

Official advice recommends travelling outside cities during daylight where possible. This matters especially on rural roads with limited lighting and medical support.

In remote areas, do not leave established roads or marked paths in former conflict zones. Landmines and unexploded ordnance remain a risk in parts of the country, particularly near some borders.

Local norms and respectful behaviour

Cambodia’s tourism centres are generally accustomed to foreigners, but cultural boundaries still matter.

Dress modestly at temples. Do not climb restricted structures, touch carvings, interrupt worship or use religious spaces as photo props.

A calm tone is usually more effective in disagreements. Ask before photographing people, monks or children at close range. APSARA also asks visitors not to give money to children at tourist sites.

Cambodia has its own legal system. Behaviour that might be treated casually elsewhere can have more serious consequences.

Emergency numbers and assistance

Main emergency numbers are:

• police: 117;
• fire service: 118;
• medical emergency: 119.

Also save the direct number for your insurer and a chosen private hospital. An assistance company does not replace an emergency call when delay could be dangerous.

Keep the hotel address both as text and as a map pin. A small guesthouse name may be unknown to an emergency operator or driver.

Consular support can assist with a lost passport, detention or a major emergency. It is not a substitute for resolving an ordinary disagreement with a hotel, bank or driver.

Common first-trip mistakes

Confusing e-Arrival with a visa

A completed free declaration does not create a right of entry if your passport requires a visa.

Using the old PNH code

Commercial passenger flights serving Phnom Penh now use KTI. The correct code matters for both transport and immigration documents.

Planning to enter overland from Thailand

The land border remains closed and the border region carries elevated risk.

Carrying only large US-dollar notes

Small purchases become difficult, and damaged notes may be rejected.

Booking every day with no flexibility

Heat, rain, delays and fatigue make a free day more valuable than one extra prepaid excursion.

Holding a phone near the open edge of a tuk-tuk

This makes it easy to grab from a passing motorbike.

Renting a motorbike on the first day

Unfamiliar traffic, unclear documentation and a poor helmet compound the risk.

Visiting Angkor in unsuitable clothing

Access rules apply in some areas, and the temples remain active religious sites.

Trying to see the whole country in four days

The result is usually a trip made up of airports, transfers and early alarms.

Conclusion: a good first trip leaves room for reality

Cambodia does not require expedition-level preparation. Most practical needs can be managed with a smartphone, official electronic forms, a local SIM card and ride-hailing applications.

A few details should not be left until the last moment. Your passport should have at least six months’ validity. eVisa and e-Arrival are separate. Phnom Penh’s airport uses KTI. The land border with Thailand remains closed in June 2026, and sensitive border areas should be avoided.

On the ground, combine riel, clean US-dollar notes, a bank card and a backup payment method. Use official Angkor tickets and dress appropriately for temples. Insurance should cover hospitalisation and medical evacuation, while mosquito protection is sensible even on a route limited to Phnom Penh and Siem Reap.

The first trip is better when the schedule has breathing space. Cambodia is difficult to understand through the window of a transfer vehicle between five attractions. A few ordinary hours in a residential neighbourhood, supermarket, café and tuk-tuk often reveal more about the country than a checklist of sights completed in a single week.
