A Mekong River cruise Cambodia is possible down the full length of the river, as it is navigable for its entire course here. Some Cambodia river cruises sail south into the Mekong Delta of Vietnam and north where the border is marked by the Mekong River in Thailand and Mekong River in Laos. These longer cruises are almost all on intimate luxury cruise ships accommodating from only 6 to 40 passengers and offering air conditioning, fine gourmet dining, and sumptuously furnished staterooms and suites. Within Cambodia, you can also book two and three-day cruises on local ferries. You might be sitting on a hard bench, but the scenery is worth it; the ferries dock in small towns at night where you can find lodging in small guest houses and Mekong River hotels. The short 100 or so miles of river north of Phnom Penh is the only place to see the few critically endangered Mekong River dolphins.
Your Mekong River cruise Cambodia can also be an excursion of only a half or full day in length. If you are staying in the capital city of Phnom Penh, you can book short sightseeing cruises, sunset cocktail cruises, and even romantic dinner cruises. About 50 miles north of the capital is Tonle Sap (Great Lake), the largest lake in Southeast Asia. This is part of the Mekong River system, and floods all the way to Phnom Penh during the monsoon. Here you can enjoy motor cruising and even water skiing. While here, you definitely want to visit Siem Reap and the incredible temple complex of Angkor Wat. If you want Cambodia river cruises that are a bit more adventurous, you will find white water rafting and kayaking in the northeast of the country, where you can also visit sill tribe villages of the ethnic Khmer Loeu people.
