Our family had a wonderful 2-weeks trip through Vietnam, Laos, Cambodia. My husband and I loved exploring history and culture of destinations, my kids enjoyed learning to cook Vietnamese meals. Everything was well organized and we had a great time in Southeast Asia.

Halong Bay is a UNESCO World Heritage site -- and you'll be reminded of this several times throughout your tour. UNESCO has picked out 830 World Heritage sites around the world, chosen for their cultural and historical importance, and also for their geological uniqueness. Halong Bay offers a little of all three.
It's not the cliffs themselves that make Halong Bay unique, but rather their sheer number. A huge bay, dotted with nearly 2,000 mostly uninhabited limestone cliffs, the breathtaking scenery is very similar to that of the Andaman coast of Thailand, Vang Vieng in Laos and Guilin in China.
Experience the majesty of Halong Bay on a traditional junk cruise. Admire the spectacular scenery, explore islets in the bay, and participate in activities such as kayaking and swimming. Enjoy a Vietnamese cooking class on board.
It was a great trip!! our tour manager was incredible and all the other guides in each country were also amazing. Shoutout to our guide is Malaysia!! He was so passionate and gave us a great true experience of Malaysia.
Bangkok to Singapore Adventure is a bit different from other contiki trips since we joined an already existing group and there were people joining and leaving throughout.

I've loved all the G Adventures tours -- the small groups, the interesting itineraries, and the enthusiastic, knowledgeable and very competent guides (and drivers too!). All three trips I've been on were fantastic introductions to the country (India, Turkey, and now China and Vietnam). I'm already looking ahead to what my next adventure might be!
