Overview
Cambodia sits in 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. It is home to roughly 16 million people and covers an area of about 181,000 square kilometres. The country's landscape is dominated by the vast Tonlé Sap lake — the largest freshwater lake in Southeast Asia — and the Mekong River, both of which shape agriculture, livelihoods, and ecology.
Most travelers know Cambodia primarily through Angkor, the sprawling medieval capital of the Khmer Empire that reached its peak between the 9th and 15th centuries. Angkor Wat itself is the world's largest religious monument and remains a functioning place of worship. Beyond Angkor, Cambodia offers a capital city with a complicated recent history, a growing coastline of beaches and islands, dense jungle wildlife corridors, and a food culture that is underappreciated even by regional standards.
Cambodia emerged from the devastation of the Khmer Rouge era (1975–1979) and subsequent civil conflict and has undergone significant economic development since the 1990s. Poverty reduction has been real, though inequality and governance challenges persist. Travelers benefit from understanding this context — it deepens appreciation for the country's resilience and shapes more respectful interactions.
Before You Go
Visas
Cambodia requires most foreign nationals to have a visa to enter. Requirements, fees, and eligibility change periodically. Check TravelerPulse's Visas section for current guidance and always verify directly with the official Cambodian Ministry of Foreign Affairs and International Cooperation or its immigration authority before traveling.
Health
Consult a travel medicine clinic at least four to six weeks before departure. Vaccinations for hepatitis A and B, typhoid, and tetanus are commonly recommended; Japanese encephalitis and rabies vaccination may be advised depending on itinerary and duration. Malaria prophylaxis is considered for rural and forested areas, particularly in provinces bordering Thailand and Laos, though urban Phnom Penh and Siem Reap carry negligible malaria risk. Dengue fever is present year-round countrywide; mosquito repellent is essential. Drink only bottled or purified water.
Travel Insurance
Travel insurance with comprehensive medical evacuation cover is strongly recommended. Medical facilities outside Phnom Penh and Siem Reap are limited. Serious medical emergencies often require evacuation to Bangkok, Thailand.
Entry Requirements
- Valid passport (verify minimum validity requirement with the issuing authority)
- Visa or pre-approved entry document (see above)
- Return or onward ticket may be requested at entry
- Verify any current health or entry documentation requirements before flying
Getting There
By Air
Cambodia's three main international airports are Phnom Penh International Airport (PNH), Siem Reap-Angkor International Airport (SAI — the newer facility that replaced the old Siem Reap airport), and Sihanoukville International Airport (KOS). Phnom Penh has the most international connections, with direct routes from regional hubs including Bangkok, Singapore, Kuala Lumpur, Ho Chi Minh City, Hong Kong, and several Chinese cities. Airlines and route availability change frequently; check current schedules with carriers or aggregators at time of booking.
By Land
Cambodia shares land border crossings with Thailand, Vietnam, and Laos. Several crossings are open to foreign nationals and accessible by bus or private vehicle. The Poi Pet–Aranyaprathet crossing (Thailand) and Moc Bai–Bavet crossing (Vietnam) are among the most frequently used by travelers. Verify current operating status and hours of any crossing before making it part of your itinerary, as hours and accessibility can change.
By River
Some travelers enter from Vietnam via the Mekong River between Chau Doc (Vietnam) and Phnom Penh. Ferry services on this route exist, though schedules and operators vary seasonally. Confirm current availability locally or through accommodation in advance.
Getting Around
Between Cities
Long-distance bus services are the most common and affordable way to travel between major destinations. Several established bus companies connect Phnom Penh, Siem Reap, Sihanoukville, Kampot, Kep, and other towns. Journey times can be long and roads vary in quality — the main national highways are generally paved, but rural roads can be rough. Domestic flights between Phnom Penh and Siem Reap are available and reduce a 5–6 hour bus ride to around 45 minutes; verify current carriers and schedules at time of booking.
Within Cities and Towns
Tuk-tuks (motorcycle-taxis pulling a covered carriage) are the iconic short-distance option in Siem Reap and Phnom Penh. Ride-hailing apps operate in both cities and typically display fares upfront. Motodops (motorcycle taxis) are faster and cheaper for solo travelers comfortable with the roads. Car rental with driver is widely available and practical for day trips to sites outside cities. Self-drive motorbike rental is possible but carries meaningful risk — traffic rules are inconsistently observed, road conditions vary, and emergency medical response is limited.
Around Angkor
Most visitors to Angkor hire a tuk-tuk driver for the day or multiple days. Cycling is possible and popular for the smaller circuits in cooler months, though the distances between major temples are substantial. Some visitors hire a car and driver for air-conditioned comfort, particularly during the hot season (March–May).
Things to See & Do
Angkor Archaeological Park (Siem Reap Province)
Angkor is the centerpiece of most Cambodia itineraries and rightfully so. The park encompasses dozens of temple complexes spread across a large area of forest and former urban landscape. Angkor Wat itself — a 12th-century Hindu-turned-Buddhist temple — is the visual and spiritual core. Ta Prohm, famous for the trees growing through its stone galleries, and Bayon, with its hundreds of carved stone faces, are must-visits. Serious temple enthusiasts can spend a week exploring outer circuits. Passes are required for entry; purchase at the official Angkor Enterprise ticketing office — do not buy from touts. Sunrise at Angkor Wat is extremely crowded; consider visiting at other times or explore lesser-visited temples at dawn instead.
Phnom Penh
Cambodia's capital sits at the confluence of the Mekong and Tonlé Sap rivers. The Royal Palace and Silver Pagoda complex are significant cultural landmarks and open to visitors. The National Museum of Cambodia holds the world's most important collection of Khmer art and sculpture. The Tuol Sleng Genocide Museum (S-21) and the Choeung Ek Genocidal Center (the "Killing Fields") are sobering but essential visits for understanding the Khmer Rouge period — approach both with the seriousness they deserve. The riverfront promenade is a pleasant place to walk, particularly in the evening.
Kampot and Kep
These small southern towns are popular for a slower pace. Kampot sits on a river near the Elephant Mountains and is the center of Cambodia's famous pepper-growing region. Kep is a former French colonial resort town with a crab market and beach, and proximity to Rabbit Island (Koh Tunsay). Both towns are within easy day-trip distance of each other.
Coastal Islands and Sihanoukville
The Gulf of Thailand coast has several islands worth visiting — Koh Rong and Koh Rong Samloem are the largest and most developed, with beaches, bioluminescent plankton visible at night in some spots, and varying levels of resort infrastructure. Sihanoukville, the departure point for most island ferries, has changed significantly over the past decade and is largely oriented toward infrastructure and transit rather than tourism in the town itself.
Wildlife and Nature
- Cardamom Mountains: One of Southeast Asia's largest remaining forest blocks; trekking and wildlife spotting including sun bears, elephants, and gibbons (guides required and recommended)
- Tonlé Sap Lake: Boat tours of floating villages; best visited during high-water season (roughly August–January) when the lake is at its most expansive
- Mondulkiri Province: Rural northeastern province known for elephants (several ethical elephant sanctuaries operate here), waterfalls, and indigenous Bunong communities
Food & Drink
Cambodian cuisine shares some ingredients with its neighbors but has its own distinct character, built around freshwater fish from the Tonlé Sap, rice, aromatic herbs, and a fermented fish paste called prahok that provides a savory depth found in few other cuisines globally. Amok (fish or chicken steamed in coconut milk and kroeung spice paste, traditionally served in a banana leaf) is probably Cambodia's most internationally recognized dish. Bai sach chrouk — sliced pork grilled over charcoal and served over rice with pickled vegetables — is a classic breakfast found at simple market stalls across the country.
Street food is abundant and affordable, particularly at morning and evening markets. Nom banh chok (rice noodles with a fresh green fish-based curry for breakfast) is worth seeking out. Lok lak (stir-fried beef with lime-pepper dipping sauce) is a widely available and reliably good lunch or dinner option. Kampot pepper, grown in the region of the same name, is considered among the world's finest and appears in local dishes and upscale restaurant menus alike.
For drinks, sugarcane juice, fresh coconut water, and iced coffee with sweetened condensed milk are staples. Angkor Beer is the dominant local lager and is inexpensive. A range of local and regional spirits are available; exercise the usual caution with unlabeled or home-produced alcohol.
Phnom Penh and Siem Reap both have well-developed restaurant scenes ranging from humble local eateries to internationally trained chefs offering refined Khmer menus. Several restaurants in both cities operate social enterprise models, employing and training at-risk youth — these are worth supporting and are easy to identify through local guides.
Shopping
Cambodian crafts have strong historical roots in silk weaving, silverwork, wood carving, and stone sculpture. Silk scarves and sampots (traditional garments) woven on handlooms are among the most enduring purchases. Several NGO-run and fair-trade shops in Phnom Penh and Siem Reap sell crafts that directly support artisan communities — these are generally well-labeled and worth seeking out over generic tourist goods.
The Phsar Thmei (Central Market) in Phnom Penh is an art deco landmark as much as a marketplace, selling gold jewelry, watches, clothing, and food. The Russian Market (Phsar Tuol Tom Poung) in Phnom Penh is popular for local goods, clothing, and handicrafts at negotiable prices. Siem Reap's Old Market area has a high density of souvenir shops; quality and authenticity vary considerably — look for pieces made in Cambodia rather than imported goods.
Do not purchase items that appear to be archaeological artifacts or antiques removed from temple sites. Such purchases are illegal, unethical, and contribute to the ongoing looting of Cambodia's cultural heritage. Buying reproductions from reputable workshops is an entirely different matter and supports local artisans.
Practical Information
Money
The US dollar functions as a parallel currency throughout Cambodia and is accepted for most transactions in tourist areas. Cambodian riel is used primarily for small change — amounts below one dollar are typically returned in riel. ATMs dispensing US dollars are widely available in cities and major towns. Notify your bank before traveling. Credit cards are accepted at larger hotels, restaurants, and tour operators but less so at markets and smaller establishments.
Connectivity
SIM cards from local providers are inexpensive and widely available at the airport and in cities. Data packages are affordable and coverage is generally good in urban areas and along main highways. Some rural and jungle areas have limited signal.
Electricity
Cambodia uses 230V/50Hz electricity. Plug types C, A, and G are found; a universal adapter is recommended.
Emergency Contacts
Cambodia's national emergency numbers: Police 117, Ambulance 119, Fire 118. Verify these are current locally on arrival. The quality and response time of emergency services varies significantly outside major cities.
Tipping
Tipping is not a strict cultural expectation but is appreciated in the tourism industry. A small tip for tuk-tuk drivers who spend a full day with you, for restaurant servers, and for hotel staff is a welcomed gesture and meaningful given local income levels.
Phone Prefix
Country code +855.
Safety
Cambodia is generally safe for travelers who exercise standard caution. Petty theft — including bag snatching from moving motorbikes — occurs in Phnom Penh and tourist areas; keep bags on your lap or the side away from traffic, avoid displaying expensive jewelry or electronics, and be aware in crowded markets.
Road safety is a genuine concern. Traffic accidents are one of the leading causes of injury among travelers. Roads can be poorly lit at night, traffic rules are inconsistently followed, and alcohol is a factor in many accidents. Avoid road travel at night where possible, wear a helmet on any motorbike, and assess road conditions carefully.
Unexploded ordnance (UXO) remains a hazard in rural areas, particularly in provinces that saw heavy bombing during the Vietnam War era (Kampong Cham, Kratie, Ratanakiri, Mondulkiri, Preah Vihear, and parts of the northwest). Stick to marked paths in rural areas and do not touch unfamiliar metal objects on the ground.
Scams targeting tourists exist, most commonly in Siem Reap and Phnom Penh — the tuk-tuk driver directing you to a closed temple or a gem investment scheme are well-documented. Book accommodation and transport through established channels and be skeptical of unsolicited assistance. Check your government's current travel advisory for Cambodia before departing.
Local Culture & Etiquette
Cambodian culture is deeply rooted in Theravada Buddhism, which arrived in the region around the 13th century and shapes daily life, festivals, and ethical norms. Wats (temples and monasteries) are the social and spiritual center of communities; monks in orange robes are a constant presence. When visiting temples — including Angkor — dress modestly: shoulders and knees covered for all genders. Remove shoes before entering shrines. Do not touch or photograph monks without permission, and women should avoid physical contact with monks.
The traditional greeting is the sampeah — hands pressed together at chest height with a slight bow, similar to the Indian namaste. Shaking hands is common in business contexts and with tourists. Public displays of anger or frustration are considered deeply inappropriate; maintaining calm and a measured tone in difficult situations will always produce better results than confrontation.
The Khmer Rouge period (1975–1979) and its aftermath remain within living memory for a large portion of the population. Be thoughtful in how you approach these topics in conversation; listen more than you speak, and recognize that individual families carry complex grief. The subject is not taboo, but how you engage matters considerably.
Khmer New Year (Chaul Chnam Thmey), celebrated in mid-April, is the country's largest festival and a major occasion for family gatherings and temple visits. Pchum Ben (Festival of the Dead), which falls in September or October, is a deeply important 15-day religious observance when people honor ancestors. Traveling during these periods offers cultural richness but expect some businesses to be closed and transportation to be crowded.
