Cambodia Airports & Ground Transportation
One big question for travelers is which Cambodia airport to fly into. Here’s a quick guide to Cambodia’s airports and how to get to the city from each:
Phnom Penh International Airport (PNH)
Phnom Penh International Airport is the main airport serving Cambodia's capital. Just a few miles west of the city center, it’s super easy to get into town after you land. The airport has modern facilities, including several shops, restaurants, and lounges to relax in before your flight. Getting to and from the city is straightforward, with taxis, tuk-tuks, and airport buses readily available right outside the terminal. The Airport offers a range of duty-free shopping and dining options, ensuring you can grab those last-minute souvenirs or enjoy a meal before departure. Traveling to the city center typically takes around 30 to 45 minutes by taxi, depending on traffic conditions, making it a convenient gateway to explore Phnom Penh's attractions.
Tip: Make sure to exchange some currency upon arrival to pay for local transportation.
Other airports
Hey there, jet-setter! While Phnom Penh International Airport is your main gateway, consider these alternatives: Can Tho International Airport in Vietnam is about 100 miles away, but the bus ride to Phnom Penh can be quite long, around 6-7 hours! Alternatively, you could also arrive through Rach Gia Airport (also in Vietnam), and then take a ferry or bus (the ferry being a more scenic experience!).
Airport transfers
Getting around from Phnom Penh International Airport is a breeze! You can hop into a taxi or tuk-tuk right outside the terminal for a quick ride to the city center. Alternatively, consider booking a private transfer in advance for a smoother arrival.
What to Do in Cambodia
Cambodia isn’t just about getting there – it’s about enjoying the country once you arrive! Here are some top things to do in Cambodia, organized by interest:
Sightseeing & landmarks
Phnom Penh's royal heritage shines at the Royal Palace and Silver Pagoda. Explore the poignant history of the Khmer Rouge regime at the Tuol Sleng Genocide Museum and the Killing Fields (Choeung Ek).
Arts & culture
Immerse yourself in Cambodian arts by catching a traditional Apsara dance performance. Discover local artists and galleries showcasing contemporary and traditional works.
Food & nightlife
Indulge in the flavorful Khmer cuisine with a cooking class or a street food tour. As the sun sets, explore the riverside bars and rooftop lounges for a vibrant nightlife experience.
Shopping & fashion
Hunt for unique souvenirs and handicrafts at the Central Market (Phsar Thmey) or the Russian Market (Phsar Toul Tom Poung). Explore boutiques featuring local designers and silk products.
Nearby getaways
Take a refreshing escape to Oudong, the former capital, with its impressive stupas and panoramic views. Alternatively, explore the Tonle Sap lake and floating villages for a unique cultural experience.
No matter your interest – be it art, food, nightlife, or nature – Cambodia has something for everyone. And the best part? Many events and attractions refresh throughout the year, so there’s always something new to experience each visit.
