Overview
Cambodia sits at the heart of mainland Southeast Asia, bordered by Thailand to the northwest, Laos to the north, Vietnam to the east, and the Gulf of Thailand to the southwest. Its geography ranges from the vast floodplain of the Tonlé Sap lake — the largest freshwater lake in Southeast Asia — to forested highlands in Mondulkiri and Ratanakiri provinces, and a coastline of relatively undeveloped beaches.
The country is indelibly shaped by two defining historical arcs: the grandeur of the Khmer Empire (roughly 802–1431 CE), which produced the architectural marvel of Angkor, and the catastrophic Khmer Rouge period (1975–1979) and its long aftermath. Understanding both is essential to understanding modern Cambodia. The population is predominantly Khmer-speaking Buddhist, with significant Vietnamese and Chinese communities.
In recent decades Cambodia has seen rapid economic growth and a steady rise in tourism. Infrastructure is improving but remains uneven outside major cities. Phnom Penh, the capital, is a dynamic, complex city. Siem Reap is the gateway to Angkor. Battambang offers a slower, more authentically Cambodian town experience. The south coast — Sihanoukville, Kep, and Kampot — attracts visitors seeking beaches and a different pace.
Before You Go
Visas
Most nationalities require a visa to enter Cambodia. Do not rely on this guide for current requirements — rules change. Check the TravelerPulse Visas section and the official Cambodian e-visa portal (evisa.gov.kh) before booking. An e-visa option has historically been available for many nationalities, and visas on arrival have been offered at major ports of entry, but verify current arrangements before travel.
Health
Consult a travel medicine clinic at least four to six weeks before departure. Malaria risk exists in forested border regions, though not in Phnom Penh or Siem Reap town centres — discuss prophylaxis with your doctor based on your itinerary. Dengue fever is present throughout the country. Ensure routine vaccinations are up to date; hepatitis A and typhoid are commonly recommended. Drink bottled or purified water only.
Travel Insurance
Comprehensive travel insurance including medical evacuation is strongly recommended. Serious medical cases are often evacuated to Bangkok, Thailand, so coverage should reflect cross-border care costs.
Currency Notes
US dollars function as a de facto parallel currency in Cambodia and are widely accepted in hotels, restaurants, and shops. Riel is most commonly encountered as small change. ATMs are available in cities and major tourist towns. Carry some cash when travelling to rural areas.
Getting There
By Air
Cambodia's two main international airports are Phnom Penh International Airport (PNH) and Siem Reap-Angkor International Airport (SAI, which opened in late 2023, replacing the older Siem Reap airport). A third international airport serves Sihanoukville. Direct flights connect Phnom Penh and Siem Reap to major regional hubs including Bangkok, Singapore, Kuala Lumpur, Ho Chi Minh City, Hong Kong, and Seoul, among others. Nonstop service from Europe or North America is limited — most travellers connect through a regional hub.
By Land
Cambodia shares land border crossings with Thailand, Vietnam, and Laos. Several crossings are open to foreign nationals and are commonly used by overland travellers on Southeast Asia circuits. Border crossing conditions, opening hours, and accepted visa types vary — verify current status before travel. Buses connecting to Bangkok, Ho Chi Minh City, and other regional cities operate from Phnom Penh and Siem Reap.
By River
A scenic passenger ferry route historically linked Phnom Penh and Siem Reap via the Tonlé Sap, though the service and its seasonal availability should be confirmed locally before planning around it.
Getting Around
Between Cities
Air-conditioned buses operated by several private companies are the most common form of intercity transport and are generally affordable. Journey times are long by distance — road quality varies considerably. Domestic flights connect Phnom Penh to Siem Reap and occasionally other destinations; check current operators as the market has been volatile. Shared taxis exist but comfort and safety standards vary.
Within Cities
Tuk-tuks (motorbike-pulled carriages) remain a popular and practical way to get around Siem Reap. In Phnom Penh, app-based ride-hailing services (including local apps) have become the dominant mode for many travellers. Motorbike taxis (motos) are ubiquitous and cheap but carry higher accident risk. Cycling is viable and enjoyable in Siem Reap and some smaller towns.
Self-Drive and Motorbike Rental
Motorbike rental is widely available in tourist towns. Traffic conditions outside cities can be unpredictable, roads may be poorly marked, and emergency medical infrastructure in rural areas is limited. Travellers who choose to self-drive should have appropriate experience and ensure their insurance policy covers this activity.
Road Conditions
National Highway 1 (Phnom Penh to the Vietnamese border) and Highway 6 (Phnom Penh to Siem Reap) are sealed but can be congested. Many provincial and rural roads are unpaved and become difficult or impassable in the wet season. A 4WD vehicle is advisable for visiting remote areas such as Mondulkiri or Preah Vihear during or after heavy rain.
Things to See & Do
Angkor Archaeological Park, Siem Reap Province
The Angkor complex is Cambodia's defining attraction and one of the most significant archaeological sites in the world. The park encompasses dozens of temples built primarily between the 9th and 15th centuries. Angkor Wat itself — the world's largest religious monument — is the centrepiece. Angkor Thom, the Bayon, Ta Prohm, Preah Khan, and Banteay Srei are among the other major sites worth visiting. Multi-day passes allow more time to explore at a considered pace; purchase through the official Angkor Enterprise authority. Sunrise at Angkor Wat is popular — arrive early. Hiring a licensed, knowledgeable guide enriches the experience significantly.
Phnom Penh
The capital rewards time beyond a transit stop. The Royal Palace and Silver Pagoda complex is an active royal residence with sections open to visitors. The National Museum of Cambodia holds an outstanding collection of Khmer sculpture and artefacts. The Tuol Sleng Genocide Museum (S-21), a former Khmer Rouge security prison, and the Choeung Ek Genocidal Center (the Killing Fields) are difficult but historically essential sites. The riverfront Sisowath Quay district along the Tonlé Sap and Mekong rivers is a pleasant area for walking.
Battambang
Cambodia's second-largest city has a well-preserved French colonial streetscape, active artist and craft communities, and a relaxed pace. The surrounding countryside is agricultural and scenic. The Bamboo Train (norry) — a local improvised rail conveyance — has historically operated near the city and is a quirky, memorable short excursion, though its current status should be verified locally.
South Coast: Kampot, Kep, and Sihanoukville
Kampot is a riverside town known for its French colonial architecture, relative tranquility, and the nearby Bokor Hill Station, a ghost-town resort complex from the colonial era set in Bokor National Park. Kep is a small former resort town famous for its crab market and proximity to Rabbit Island (Koh Tonsay). Sihanoukville remains Cambodia's main beach hub, though it has changed significantly in recent years — conditions there are best researched with current sources before visiting.
Mondulkiri and Ratanakiri
These northeastern provinces offer highland landscapes, ethnic minority villages, wildlife, and a Cambodia very different from the tourist trail. The Cardamom Mountains and Virachey National Park offer more serious wilderness. Community-based tourism projects operate in several areas — look for responsible operators.
Landmine Awareness
Cambodia remains one of the most heavily mined countries in the world, primarily in the northwest near the Thai border. Never walk off marked paths in rural or forested areas. The Cambodian Mine Action Centre (CMAC) and organisations like HALO Trust work on clearance; the situation is improving but ongoing.
Food & Drink
Khmer Cuisine
Cambodian food shares some characteristics with Thai and Vietnamese cooking but has its own distinct identity. Amok — a steamed fish or chicken curry in coconut milk and kroeung (lemongrass-based paste), traditionally cooked in banana leaf — is probably the most internationally recognised Khmer dish. Bai sach chrouk (grilled pork over broken rice, typically a breakfast dish), num banh chok (rice noodles with fish-based green curry sauce), and lok lak (stir-fried beef with lime and pepper dipping sauce) are other staples worth seeking out.
Prahok
Prahok — fermented fish paste — is a foundational ingredient in Khmer cooking, providing deep umami flavour. It is often used as a condiment or base, and its presence in a dish is not always immediately obvious. Travellers with fish allergies should ask carefully.
Street Food and Markets
Markets are excellent places to eat economically and well. Phnom Penh's Central Market (Phsar Thmei) and Russian Market (Phsar Tuol Tom Pong) areas have food stalls. In Siem Reap, the Night Market area and Pub Street surroundings cater heavily to tourists; for more local eating, wander into residential streets around the old market.
Drinks
Angkor and Cambodia beers are widely available and inexpensive. Fresh coconuts, sugarcane juice, and fruit smoothies are popular non-alcoholic options. Cambodian coffee — often served with sweetened condensed milk over ice — is very good. Tap water is not safe to drink; use bottled or properly filtered water, including for brushing teeth.
Shopping
Cambodia produces beautiful silk textiles, and silk scarves, sarongs, and krama (traditional checked cotton scarves) make meaningful, locally made purchases. Siem Reap has numerous craft shops; look for retailers that work directly with artisans or weaving villages. The Artisans Angkor operation, associated with the Chantiers-Écoles, employs local craftspeople and sells reliably sourced products.
Antiques, including items that appear to be Khmer artefacts, are frequently sold at markets. Exporting genuine archaeological artefacts is illegal under both Cambodian law and international conventions — exercise extreme caution and assume that anything sold as an 'authentic' ancient item is either a reproduction or illegally obtained.
Silver jewellery, lacquerware, stone carvings (reproduction), and handmade paper products are other common purchases. Bargaining is normal in markets but not in fixed-price shops. In general, the gap between asking price and reasonable price in tourist markets is significant; approach with patience.
Practical Information
Emergency Contacts
Emergency service numbers in Cambodia should be verified locally or through your accommodation upon arrival, as numbers and reliability vary. Your country's embassy in Phnom Penh is an important contact to register with before travel.
Electricity
Cambodia uses 230V/50Hz. Outlets vary — types A, C, and G plugs are all encountered. A universal travel adapter is useful.
Mobile and Internet
Local SIM cards are cheap and easy to obtain. Several networks offer good 4G coverage in cities and along major highways; coverage drops in remote areas. Wi-Fi is widely available in guesthouses, cafes, and restaurants in tourist towns.
Dress and Temples
Shoulders and knees must be covered when visiting active temples and pagodas. This applies equally to all genders. Some sites provide sarongs for rental at the entrance if you arrive underprepared, but carrying a light scarf or krama is practical and respectful.
Tipping
Tipping is not a traditional Cambodian custom but is appreciated in the tourism sector, where wages are low. A small tip for guides, drivers, and hotel staff is a meaningful gesture. Many restaurants add a service charge; check the bill.
Safety
Cambodia is generally safe for travellers exercising normal urban caution. Bag snatching from moving motorbikes is the most commonly reported crime in Phnom Penh and Siem Reap — carry bags on the side away from traffic, avoid displaying expensive items, and be alert at night. Keep a photocopy of your passport separate from the original.
Landmines and unexploded ordnance (UXO) remain a genuine hazard in rural northwestern Cambodia, particularly near the Thai border. Always stay on marked paths in rural areas and do not pick up or disturb unfamiliar objects.
Road safety is a significant concern. Traffic accidents, including involving tourists on hired motorbikes, are a leading cause of serious injury in Cambodia. Helmets are legally required and should always be worn. Night driving carries additional risk.
Petty corruption involving police or officials is sometimes reported. If approached for unofficial 'fines,' remain calm and politely ask for an official receipt. Consult your embassy's travel advisory pages for current safety assessments — these are updated more frequently than any travel guide.
Local Culture & Etiquette
Cambodia is a predominantly Theravada Buddhist country, and the rhythms of daily life — morning alms rounds by monks, temple festivals, and lunar calendar observances — reflect this. Showing respect to monks (maintain physical distance, particularly if you are a woman) and to elders is important. The traditional Khmer greeting is the sampeah — pressing palms together at chest level and nodding — and using it is appreciated.
The legacy of the Khmer Rouge period is present everywhere, in ways both visible and invisible. Approximately a quarter of the country's population perished between 1975 and 1979. Many Cambodians over a certain age have direct personal experience of severe trauma and loss. Visitors should approach this history with humility and sensitivity — it is not a curiosity but a living wound in Cambodian society. Sites like Tuol Sleng and Choeung Ek deserve to be visited thoughtfully and quietly.
Khmer New Year (Chaul Chnam Thmey), typically celebrated in mid-April, is the most important annual festival and a major time of family reunion and travel within the country. The Water Festival (Bon Om Touk), celebrating the reversal of the Tonlé Sap River's flow, is held in November and draws large crowds to Phnom Penh. Both periods affect availability of accommodation and transport — book well ahead if travelling then.
