Each country offers a different visa policy. For the cruise between Vietnam and Cambodia, we will separate into two distinct routes:

• Upstream: You can get Vietnam & Cambodia visas on arrival (VOA) with an approval letter for Vietnam and pay stamp fees at the airport or river border.
• Downstream: You can get a Cambodia visa on arrival when you arrive for a Vietnam visa (since you cannot get a VOA at the border, you need to make a visa before arriving). We could support you in getting an urgent visa at the Vietnam Embassy in Cambodia with fees of US $85 if you don't have a visa before arriving.

I hope this information will help you know how to do it or please contact our travel consultant if you need more help.

The shortest cruises from Saigon/Can Tho (Vietnam) to Phnom Penh (Cambodia) typically take between 3 to 4 days, depending on the itinerary. 

If you are already at the border between two countries, you will need around 4-5 hours on a high-speed boat. However, a full Vietnam Cambodia cruise lasting several days offers stops for sightseeing and cultural experiences, which are much more valuable.

The best months for a Mekong River cruise are from November to April. During this time, the weather is cooler and drier, with lower humidity, and less rainfall, offering more comfortable cruising conditions and better visibility for sightseeing. This season is also less likely to experience flooding, which can affect some travel routes.

The Mekong River cruise between Vietnam and Cambodia has 2 directions:

• Upstream: Departing from Vietnam (Saigon/ Can Tho to Siem Reap/ Phnom Penh)
• Downstream: Departing from Cambodia (Siem Reap/ Phnom Penh to Saigon/ Can Tho) 

The only difference is the start/end point. Both routes offer similar destinations and experiences onboard, you will not miss anything if you choose one of them. Let's choose the one that is most convenient for your post-cruise travel plan.
