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!
