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!

From the Mekong Delta to Siem Reap (port-to-port cruise) - September 2026

No booking fees

Best price guaranteed

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.
