Budget travelers will find hostels the best option, with accommodation ranging between $5 and $15, depending on the room type, while staying in hotels will cost around $60 per night.

Where to go in Cambodia in March

March is one of the best times to be in Cambodia. It’s dry and hot, but not unbearable yet, so you can actually enjoy long days exploring temples or heading to the coast.  Here are some of the best places to visit in Cambodia. 

Siem Reap and Angkor

March is a great time to explore Angkor. Skies are usually clear, which means sunrise and sunset over Angkor Wat actually live up to the hype. Fewer people visit compared to the winter rush, so you’ll have more space around major temples. Roads out to lesser-known temples like Koh Ker and Beng Mealea are dry and easy to travel. Evening shows and Apsara dance performances are still running, and Siem Reap’s night markets are lively with plenty of spots to eat outdoors.

Phnom Penh

The capital is in full swing this time of year. Riverside areas fill with markets, street food, and people out walking as the day cools down. The Royal Palace looks especially sharp under clear skies, and you can explore markets like the Russian Market without worrying about floods. It’s also a good time to visit Tuol Sleng and the Killing Fields, as conditions are dry and transport is reliable. The city's mix of colonial buildings and Buddhist temples is easier to appreciate when you’re not dodging downpours. See our pick of the best things to do in Phnom Penh.

Koh Rong and Sihanoukville

Island life in March feels easygoing, with calm, clear water and reliable boat connections before the monsoon season begins. It is a strong month for snorkelling or diving, and you may even catch bioluminescence during a nighttime swim. On 13-day Cambodia trips, the islands can work as a relaxed final stretch after temples, cities, and inland travel, with ferries running regularly and beachfront restaurants still in full swing.

As March sits at the tail end of high season, you can still expect good weather, often with fewer people than in the busiest weeks.

What to do in Cambodia in March

March is a great time to be out and about in Cambodia. Dry weather means easier travel, clear skies, and long days for exploring temples, beaches, and rural areas. The landscapes are still green from earlier rains, and crowds start to thin out after peak season. Here are some of the best things to do in Cambodia.

Watch sunrise at Angkor Wat

The morning light in March is usually clear and soft, making sunrise at Angkor Wat one of the best times to visit. You’ll want to get there early to find a quiet place near the reflecting pools. It’s cooler at this hour too, so you can walk through the grounds before it heats up. March is still busy, but less so than January or February, which makes the experience a little more peaceful. 

Take a boat along the Mekong

As water levels drop in March, the Mekong reveals more of its riverbanks and fishing villages. Boat trips around Kratie are ideal this time of year, and you might spot Irrawaddy dolphins in the narrower channels. Near Kampong Phluk, the stilt houses rise high above the water, and life on the river feels more visible. Sunset cruises from Phnom Penh also run regularly, with fewer tourists than in high season.  For more advice, see our Cambodia travel tips.

Join a Khmer cooking class

March evenings are warm but comfortable, perfect for open-air cooking classes. Most start with a morning visit to the local market to pick up herbs and spices. Some include short bike rides to nearby farms. You’ll learn how to make classic dishes like amok and lok lak using traditional tools. It’s a hands-on way to understand Cambodian food culture and brings back skills you can actually use.
