• Requirements: Digital passport photo, valid passport, and credit/debit card for payment

Note: E-visa is only valid at certain entry points, including Phnom Penh, Siem Reap, and Sihanoukville airports.

Cruising downstream from Siem Reap to Phnom Penh or further to Saigon is generally preferred. It follows the natural flow of the Mekong River, less affected by the currents and water levels. This direction also makes logistical sense as it ends in a major city with good flight connections.

These cruises are very enjoyable, and the scenery and cultural experiences are rich and memorable.

Here are the most recommended Cambodia Mekong River cruises for American tourists, based on price, customers’ reviews, and services:

• RV Mekong Navigator Downstream 8 days: Siem Reap - Saigon (from $2402/pax).
• Victoria Mekong Downstream 5 Days: Phnom Penh - Saigon (from $1092/pax).
• RV Mekong Princess Downstream 6 days: Phnom Penh - Saigon (from $1812/pax).
• Aqua Mekong Discovery 4 days: Phnom Penh - Siem Reap (from $3192/pax, all-inclusive).
• Heritage Line Jahan Upstream 5 days: Phnom Penh - Siem Reap (from $1482/pax).

A cruise on the Cambodia section of the Mekong River typically takes 3 to 8 days, depending on the itinerary.

• Short cruises (3 - 5 days) have two main routes: between Phnom Penh - Siem Reap (in Cambodia only) and between Phnom Penh - Saigon.
• Longer cruises (7 - 8 days) start from Siem Reap to Saigon, often including many cultural stops, historical spots, temples, and local villages.

The best time for a Cambodia Mekong River cruise is from November to February. This is the dry season, so the weather is cooler and drier, with pleasant temperatures and ideal river conditions. You can enjoy smooth cruising, comfortable sightseeing, and great access to remote areas.

March to May gets very hot but fewer touristy, while June to October is the rainy season, which can affect travel plans but offers lush scenery.

The Cambodia Mekong River cruises often cost between $148 and $300/pax/day. The price can be different based on the itinerary and the service the cruise provides.

Below are the average prices for various cruise lengths for reference (excluding transfer fees):

• 3 - 5 days Phnom Penh - Saigon: From $591 - $1,487/person.
• 3 - 5 days Siem Reap - Phnom Penh: From $714 - $1,510/person.
• 7 - 8 days Siem Reap - Saigon: From $1,514 - $2,402/person.

Unfortunately, they do not. Most Cambodia cruises start in Phnom Penh/Siem Reap port and do not include a trip to Angkor Wat.

You can contact your travel agent to book a separate tour to explore Angkor Wat before the cruise.
