How to Get to Siem Reap: Flights, Bus & Border Options

← Home

Siem Reap has its own international airport, direct bus and van links from Phnom Penh and other Cambodian cities, and overland border crossings from Thailand — so the right option mostly comes down to where you’re coming from and how much time you want to spend in transit.

By air

Siem Reap Angkor International Airport (SAI) opened in 2023 about 40 minutes outside the city and now handles the large majority of international and domestic flights, replacing the old airport closer to town. It has direct connections to major Southeast Asian hubs including Bangkok, Singapore, Kuala Lumpur, and Ho Chi Minh City, along with domestic flights from Phnom Penh and Sihanoukville.

From Phnom Penh

The most common overland route is by bus or van along National Road 6, taking roughly 5-6 hours depending on the operator and traffic. Several companies run this route multiple times daily with air-conditioned coaches; a faster but pricier option is a shared or private van, which typically shaves an hour or so off the trip. See Phnom Penh to Siem Reap: Bus, Boat and Flight Options for operator comparisons.

From Bangkok and the Thai border

Overland travel from Bangkok involves crossing at the Poipet-Aranyaprathet border, followed by onward transport to Siem Reap — a route that has a reputation for scams targeting tourists at the border itself, so going with a reputable direct bus company that handles the crossing as part of the ticket is worth the extra cost. Total travel time typically runs 8-10 hours door to door. Full details in Bangkok to Siem Reap: Border Crossing and Travel Options.

From Battambang

Battambang to Siem Reap is a shorter overland hop, roughly 3 hours by shared taxi or bus, and is a common add-on for travelers exploring Cambodia’s interior before heading to the temples. See Battambang to Siem Reap: How to Get There for current options.

Quick comparison

Phnom Penh → Siem Reap: ~5-6 hours by bus/van, or a short domestic flight
Bangkok → Siem Reap: ~8-10 hours overland via the Poipet border, or a direct flight
Battambang → Siem Reap: ~3 hours by shared taxi or bus
Sihanoukville → Siem Reap: domestic flight recommended over the long overland route

Domestic flights within Cambodia

Cambodia Angkor Air and a handful of regional carriers run short domestic routes connecting Siem Reap with Phnom Penh and, less frequently, Sihanoukville. These flights run under an hour and are worth considering if you’re short on time or coming from the coast, where the overland route is long and not particularly scenic.

What to expect on arrival

Siem Reap Angkor International Airport has a visa-on-arrival counter, ATMs, and a standard taxi/tuk-tuk rank just outside arrivals; the ride into town takes roughly 40 minutes. Most hotels can arrange a pickup for a flat fee if you’d rather not negotiate on arrival, which is worth it after a long flight.

Frequently asked questions

What’s the fastest way to reach Siem Reap from Phnom Penh?

A domestic flight takes under an hour, versus roughly 5-6 hours by bus or van overland.

Is the Poipet border crossing from Thailand safe?

It’s generally safe if you go through a reputable bus company that handles the crossing as part of the ticket; independent crossing has a higher risk of common tourist scams at the border itself.

How far is the airport from Siem Reap city center?

Siem Reap Angkor International Airport is about 40 minutes from the city center by car or taxi.

Can I get a visa on arrival at Siem Reap airport?

Yes, visa on arrival is available at the airport, though applying for the e-visa online in advance avoids the arrival queue.

Flying into Siem Reap

Siem Reap-Angkor International Airport, opened in late 2023, receives direct flights from major regional hubs including Bangkok, Ho Chi Minh City, Singapore, and Kuala Lumpur, along with a growing number of direct long-haul connections. The airport sits about 40km (45-50 minutes) from central Siem Reap, notably further than the old in-town airport it replaced, so factor in extra transfer time and cost when planning arrival logistics.

Overland from Bangkok or Phnom Penh

From Bangkok, the land route crosses at the Poipet-Aranyaprathet border, taking 8-9 hours by direct bus (around $25-35) — pre-arranging an e-visa online avoids the notorious scam visa counters that operate before the official checkpoint. From Phnom Penh, buses take 5.5-6.5 hours ($12-20), with boat (5-6 hours, $25-35, best in wet season) and short flights (under an hour, $40-70) as faster alternatives.

Which option makes sense for your trip

Flying directly into Siem Reap is the simplest choice if it’s your first Cambodia stop, especially from regional hubs with frequent direct service. If you’re already in Bangkok or Phnom Penh as part of a wider Southeast Asia trip, weigh the bus’s low cost against the flight’s time savings — for trips under 2 weeks total, the several hours saved by flying are often worth the modest extra cost.

Booking flights: timing and pricing patterns

Flight prices to Siem Reap follow predictable seasonal patterns, rising through the November-February peak and dropping noticeably during the June-September rainy season — booking 6-8 weeks ahead for peak season travel typically secures meaningfully better fares than booking within 2-3 weeks of departure, when remaining seats often carry a premium.

Combining arrival methods across a longer Southeast Asia trip

Many travelers fly into Siem Reap as a first stop and later depart overland toward Phnom Penh and onward to Vietnam, or the reverse — flying makes the most sense for whichever leg of a multi-country trip has the least flexible schedule, while overland routes work well for a middle leg where an extra travel day doesn’t disrupt onward connections.

How arrival choice affects your very first impression of Cambodia

Flying directly into the new, modern Siem Reap-Angkor International Airport offers a smooth, efficient introduction to the country, while an overland border crossing at Poipet delivers a rawer, more immediate sense of Cambodia’s contrasts and challenges from the very first hour — neither is objectively better, but it’s worth knowing which kind of first impression you’re choosing, since they genuinely differ in tone and pace.

What to do in your first few hours regardless of arrival method

Whichever way you arrive, resist the urge to head straight to the temples on arrival day — a short rest, a meal, and a walk around Old Market to get oriented sets up the following days’ temple visits far better than arriving exhausted from travel and pushing straight into sightseeing on your first afternoon.
