This tour was absolutely wonderful. We saw so many things, and whilst the pace was very fast moving I don’t feel as though I missed much of each place. We really made the most of our time in each place thanks to my tour leaders. My tour leaders were absolutely wonderful and added so much to my overall experience. This was my first time using Gadventures and I would definitely use them in the future. I would definitely recommend!!

I truly enjoyed my experience with GAdventures. The SouthEast Asia encompassed tour was a great way to see the highlights of 4 different countries. It was a great opportunity to truly experience each culture and give back to the communities. The tour leader really makes the experience as positive as it was. It wouldn’t be the same without Chen!

Prepare for an epic adventure loaded with ancient sights and natural beauty as you travel from the hustle of Bangkok to the bustle of Hanoi. In Cambodia, call into the ancient temples at Angkor, take on beguiling Phnom Penh and get a taste of Khmer hospitality with a village homestay in Chambok. Then veer into Vietnam to trace its coastline from south to north, visiting the chaotic Ho Chi Minh City all the way up to old-world Hanoi, with historic Hoi An and Hue at its centre. Along the way, revel in the sheer beauty of the landscape, the friendliness of the locals and the social organisations that are providing brighter futures for this region. Oh, and did we mention the food? To die for.

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.
