I felt the G Adventures tour provided experiences you could not get on your own, and made the travel stress-free. You spend the time enjoying the experiences and not having to think about logistics. The local guides and CEO were all fantastic cultural translators who went the extra mile to provide a rich experience.

This was a very well organised and enjoyable tour and through the guides and suppprt crew we got a really good feel for each country and its people customs history and food. The tour leader Doan was excellent throughout and always ready to help us with little things like buying food in the markets or talking and joking with locals. We felt really immersed in the local culture but also nicely protected from the sometimes hot and humid weather by our lovely air conditioned van and great accommodation choices!

The tour was the most fun and welcoming experience, from the second we all met at the first meeting until the second I was saying good bye to everyone. The tour was better then I was ever expecting and when I do a G adventures tour again I hope my CEO is just like Leo.

Even though I was the only person on this trip, I cannot thank Explore highly enough for the excellent liaison with the local partners to ensure I had a safe and seamless trip. Although most days were spent in Cambodia, it was interesting having some time in Thailand and Vietnam as well. I would highly recommend this trip.

From the heights of the Himalayas to the southern coasts of the South China Sea, winding over 2,700 miles, the Mekong is much more than just irrigation for Indochina—everywhere it flows, it fascinates men and shapes their lives. Come take an expedition on this grand and plentiful “water snake,” from Ho Chi Minh City, still largely influenced by the French colonial days, to Phnom Penh, then Tonle river, following the footsteps of Henri Mouhot. Our meditative trip takes you along the Mekong River on board a ship combining charm and colonial-style comfort.
