How Do You Get from Phnom Penh to Siem Reap
Three transport options connect Phnom Penh and Siem Reap: bus, domestic flight, and the seasonal Tonle Sap boat. For most travelers, the bus offers the best balance of affordability, comfort, and convenience. Flying is the fastest option, while the Tonle Sap boat provides a slower, more scenic journey through Cambodia’s largest freshwater lake during the high-water season.

| Flight | About 55 minutes | 280,000៛–480,000៛ ($70–$120 USD) | Travelers on a tight itinerary |

Taking the Bus from Phnom Penh to Siem Reap
The bus is the most popular way to travel from Phnom Penh to Siem Reap, offering the best combination of affordability, comfort, and frequent departures. The journey typically takes 6 to 7 hours, depending on traffic, road conditions, and scheduled rest stops, with fares ranging from 40,000៛ to 140,000៛ ($10 to $35 USD) based on the operator and seat type.
Giant Ibis is one of Cambodia’s most established bus companies, operating standard, VIP recliner, and overnight sleeper services. Other operators, including Virak Buntham and Mey Hong Transport, also run multiple daily departures, giving travelers plenty of flexibility when planning their trip.
Most long-distance buses stop once or twice along the route, allowing passengers to stretch their legs, use the restroom, and buy snacks or drinks before continuing to Siem Reap.
Booking tip: If you’re traveling during Khmer New Year or Pchum Ben, book your ticket at least 48 hours in advance. These are Cambodia’s busiest travel periods, and popular departures can sell out quickly.
Flying from Phnom Penh to Siem Reap
Flying is the fastest way to travel from Phnom Penh to Siem Reap, with flight times of around 55 minutes. Once airport transfers, check-in, and security are factored in, the total journey usually takes 3 to 4 hours, making it a practical choice for travelers on shorter itineraries.
Several airlines operate daily flights between Phnom Penh International Airport (PNH) and Siem Reap–Angkor International Airport (SAI). One-way fares typically range from 280,000៛ to 480,000៛ ($70 to $120 USD), although booking early or traveling outside peak season can help secure lower prices.
Siem Reap’s new airport is located about 45 kilometers (28 miles) from the city center. Airport shuttle buses, private taxis, and ride-hailing services are available, with most transfers taking 45 to 60 minutes, depending on traffic.
Traveler tip: A flight may save time in the air, but remember to factor in the transfer from Siem Reap–Angkor International Airport to the city. For many travelers, the overall time saved compared with the bus is smaller than expected.
When Is the Best Time to Travel from Phnom Penh to Siem Reap
The best time to travel from Phnom Penh to Siem Reap depends on the experience you’re looking for. Cambodia has two main seasons, and each affects road conditions, sightseeing, and the availability of the Tonle Sap boat.
| Season | What to Expect | Best For |
|---|---|---|
| November to February | Cooler temperatures, lower humidity, and clear skies | Visiting Angkor Wat, comfortable bus travel, outdoor activities |
| March to May | Hot and dry, with temperatures often above 35°C (95°F) | Smaller crowds and lower accommodation rates |
| June to October | Green landscapes, afternoon showers, and higher water levels | Tonle Sap boat journeys and lush countryside views |
If your itinerary is flexible, November through February offers the most comfortable conditions for traveling between the two cities and exploring Siem Reap’s temples. If you’re hoping to take the Tonle Sap boat, plan your trip during the wet season, when water levels are typically high enough for passenger services to operate.
Local tip: Leaving Phnom Penh early in the morning helps you avoid the city’s busiest traffic and gives you more time to settle into Siem Reap before exploring the Old Market or Pub Street.
How to Book Your Phnom Penh to Siem Reap Tickets
Bus and flight tickets can be booked online before your trip or purchased directly through operators and local travel agencies. During major holidays such as Khmer New Year and Pchum Ben, it’s worth booking several days in advance, as popular departures often sell out.
If you’re traveling by bus, most operators offer reserved seating, while premium services may include reclining seats, sleeper cabins, Wi-Fi, USB charging, and onboard refreshments. Flight prices tend to be lower when booked early, particularly during Cambodia’s peak travel season between November and February.
For the Tonle Sap boat, always confirm schedules before making plans. Services depend on seasonal water levels, and departures can change or be suspended during the dry season.
Planning tip: Keep a digital copy of your ticket and arrive at the departure point at least 30 minutes before departure. This gives you enough time to check in, find your platform, and avoid last-minute delays.
What to Know Before You Arrive in Siem Reap
Most buses arrive near the city center, while flights land at Siem Reap–Angkor International Airport (SAI), approximately 45 kilometers (28 miles) from downtown. Airport shuttle buses, taxis, and tuk-tuks are available, with transfers typically taking 45 to 60 minutes.
If you’re planning to visit Angkor Wat the following day, consider purchasing your Angkor Pass on arrival to save time in the morning. The ticket office is separate from the temple complex, so buying it the afternoon before your visit lets you start exploring earlier.
The Old Market (Psar Chas) and Pub Street area is the most convenient base for first-time visitors. Restaurants, cafés, bars, tour operators, and tuk-tuk drivers are all within walking distance, making it easy to settle in after your journey.
Local tip: Most tuk-tuk drivers accept US dollars, Cambodian riel, and digital payments through the Bakong QR system. Carrying small notes in riel is still useful for markets, street food, and short rides.
Where to Stay in Siem Reap
After a long journey, staying somewhere central makes it easier to explore the city on foot. The neighborhoods around Pub Street, the Old Market, and the Siem Reap River put restaurants, cafés, nightlife, and tour operators within easy reach, while Angkor Wat is only about 15 to 20 minutes away by tuk-tuk.
Mad Monkey Siem Reap is a convenient option for backpackers looking to experience the city’s social scene while staying close to the main attractions. Located just minutes from Pub Street, it offers easy access to local food, nightlife, and day trips to Angkor Archaeological Park.
