Getting to Siem Reap — Flights, Bus, Boat & Overland
The easiest and most common way to reach Siem Reap is by flying directly into Siem Reap International Airport (SAI), which receives international flights from Bangkok, Singapore, Kuala Lumpur, Hong Kong, Seoul, Tokyo, and major Chinese cities. From Phnom Penh, the most practical options are a short domestic flight (45 minutes) or a tourist bus (6–7 hours). Overland routes from Thailand via the Poipet border crossing are also widely used. Siem Reap has no rail connection.
Siem Reap is Cambodia’s second-largest city and one of Southeast Asia’s most visited destinations. Its airport received a major upgrade with the opening of the new Siem Reap Angkor International Airport (SAI) in late 2023, significantly expanding international connectivity.
Whether you are arriving from within Cambodia, from Thailand, or from further afield, this guide covers every practical option for reaching the gateway to Angkor Wat.

The transfer from SAI to Siem Reap city takes approximately 45–60 minutes by road. Flying is the fastest and most convenient option for international visitors.

Airport transfer from SAI to Siem Reap city:

- Official airport taxis (fixed-rate; approximately $25–35 to the city centre)

- Shuttle bus services operated by some hotels
Budget extra time in your arrival day itinerary for the airport transfer. Do not plan to visit the temples on the day of arrival at SAI if your flight lands in the afternoon.
By Air — Domestic Flights from Phnom Penh
A domestic flight from Phnom Penh (PNH) to Siem Reap takes approximately 45 minutes with Cambodia Angkor Air or other domestic carriers. This is the fastest way to travel between the two cities and is worth considering if your time is limited. Prices are typically $60–120 one way depending on season and availability.
By Bus — From Phnom Penh
The tourist bus from Phnom Penh to Siem Reap takes approximately 5.5–7 hours and costs $10–15 per person on reputable operators. The road (National Highway 6) is sealed and in reasonable condition. Comfortable air-conditioned coaches with reclining seats are available through operators including Mekong Express, Giant Ibis, and Virak Buntham. Buses depart from multiple points in Phnom Penh and arrive in Siem Reap near the city centre. This is the most popular budget option for independent travellers moving between the two cities.
Recommended bus operators from Phnom Penh:
- Giant Ibis — The premium option; punctual, clean, air-conditioned, with USB charging and snacks. Higher price ($15–20) but reliable. Book online at giantibis.com.
- Mekong Express — Popular mid-range operator; comfortable and reasonably priced ($10–14).
- Virak Buntham — Budget-friendly; lower fares but variable quality.
Buses depart from Phnom Penh’s central bus stations approximately every 1–2 hours from early morning. Book in advance during peak season (December–February) as seats sell out.
By Bus — From Bangkok, Thailand
Travelling from Bangkok to Siem Reap by bus involves crossing the Thai-Cambodian border at Poipet/Aranyaprathet. The full journey takes approximately 8–12 hours including the border crossing. Direct tourist buses from Bangkok’s Mo Chit or Victory Monument bus terminals to Siem Reap are available for approximately $20–30. The Poipet border crossing is Cambodia’s busiest land crossing and can be crowded and slow — allow 1–3 hours for border formalities and have your Cambodian visa ready (either e-visa obtained in advance or visa on arrival).
Recommended approach for Bangkok to Siem Reap:
- Obtain a Cambodian e-visa in advance at evisa.gov.kh ($36 + processing; available online within 3 business days)
- Take a tourist bus from Bangkok to the border — operators include Nattapol Tour, Siam Reap Shuttle, and various online booking platforms
- Cross the Poipet border on foot (the main crossing is pedestrian)
- Continue by bus, shared taxi, or private car from Poipet to Siem Reap (3–4 hours)
Note on scams at Poipet: The Poipet border crossing is notorious for scams targeting tourists — unofficial “travel agencies” offering to process your visa or book onward transport at inflated prices. Use only the official government immigration windows and pre-booked transport. Do not accept assistance from touts.
By Bus — From Ho Chi Minh City, Vietnam
Direct tourist buses operate from Ho Chi Minh City (Saigon) to Siem Reap. The journey takes approximately 12–14 hours and crosses the Moc Bai-Bavet border. Reputable operators include Sinh Tourist and Kumho Samco. This is a viable option for travellers on a Mekong region itinerary combining Vietnam and Cambodia.
By Boat — The Phnom Penh to Siem Reap River Route
A fast boat service on the Tonle Sap River and Tonle Sap Lake connects Phnom Penh to Siem Reap in approximately 5–6 hours. The boat passes through the largest freshwater lake in Southeast Asia — a scenic journey that is in itself one of the more distinctive travel experiences in the region. Prices are typically $35–45 per person. Note that the boat service operates seasonally — during the dry season (roughly November to May), water levels may be too low for reliable service, and the journey may be longer or subject to delays. Confirm current schedules before booking.
Cambodian Visa Requirements
Most nationalities require a visa to enter Cambodia. The two options are:
E-visa (recommended): Apply online at evisa.gov.kh. A single-entry tourist visa costs $36 USD plus a $6 processing fee. Processing takes approximately 3 business days. Present the approved e-visa at immigration.
Visa on arrival: Available at Phnom Penh, Siem Reap, and other major entry points. A single-entry tourist visa costs $30 USD (cash only). Bring a passport photo.
Visa-free entry is available to citizens of ASEAN member states and a small number of other countries. Check current visa requirements with the Royal Embassy of Cambodia or your country’s foreign ministry before travel.
Getting from the Airport/Bus Station to Your Hotel
From SAI airport: Fixed-rate taxis are available from the official taxi counter in the arrivals hall. Pre-booking a hotel transfer is the most stress-free option. The journey to central Siem Reap takes 45–60 minutes.
From Siem Reap bus stations: Most tourist buses drop off near the central market or at dedicated drop-off points close to the guesthouse district. Tuk-tuks are available from all bus arrival points to take you to your hotel.
