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.

Australian citizens will need a valid visa for Cambodia. Cambodia offers a few convenient options depending on your cruise direction:

• Required: Passport (valid for at least 6 months), 1 passport-size photo, cash for the visa fee.

Downstream Cruise

You'll need to obtain a Visa on Arrival at one of Cambodia's international entry points.

• Available at: Major international airports (Phnom Penh, Siem Reap, Sihanoukville) and certain land borders.
• Validity: 30 days (Tourist Visa - T class)
• Requirements: Passport (at least 6 months validity), 01 passport-sized photo, Visa fee (around 46.5 - 54.25 AUD/person), and completed visa application form (available at the airport/land border).

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

• 3 - 5 days Saigon – Phnom Penh: From 916 AUD - 2,305 AUD/person
• 3 - 5 days Phnom Penh – Siem Reap: From 1,107 AUD - 2,341 AUD/person

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.

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.
