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!

Our family of four had the best time! This was the first trip out of the country for our two teens and we couldn’t have asked for a better experience – for all of us. Our guide, Zam, was organized, helpful, knowledgeable, and funny. We really appreciated his expertise and how well he helped us navigate many different places and spaces. Our group included another family with teens and people from around the world who quickly became friends. We really liked the pacing of this tour -- a couple of days in each island -- and the flexibility on some of the days to do things with just our family instead of being locked into a very tight itinerary with the group. We added on a couple of days to see Bangkok outside of this island tour and I think that is a must-do for anyone visiting Thailand. Our favorite parts of the trip were snorkeling in the islands, hiking up to see the views in Ang Thong park, beach massages, and eating fresh and delicious Thai food.
