My journey through China and Vietnam was nothing short of amazing. From breathtaking landscapes to rich cultural experiences, every moment was a discovery. In China, I explored ancient wonders and modern marvels, while Vietnam offered me warmth, flavor, and unforgettable trails. Even when my knee gave me trouble, my guide’s kindness turned a challenge into a highlight. And the photos—wow. I came back not just with souvenirs, but with stories, gratitude, and a heart full of adventure." Thank you Tom,Nam and Luan.

Journeys: Iconic Thailand was a fabulous experience!!! We had the most wonderful tour guide (shout out to Natthanan Chai Yenklom--the very best!!!!) who looked after every detail and made the experience comfortable and enjoyable for each person on the trip. I loved the varied activities--the home visit and cooking class in Chiang Mai; Ko Klang Island and Hong Island in Southern Thailand; and the amazing temples in Bangkok were particular highlights for me on the trip. I would do another National Geographic Journeys/G Adventures tour in the future!

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!
