The north of Thailand was my FAVOURITE. I loved the diverse range of 'stays' which kept it exciting and much like an adventure and showed what Thailand had to offer. The Jungle Raft on the second night was an essential bonding experience for the group and allowed us to build friendships and enjoy the trip way more than if we hadn't had that crucial opportunity to connect. The included experiences, free time add ons, and even trip manager suggestions were all top tier! I didn't regret a single experience. 2 night stays were also a relief as travelling can get quite tiring and found that their timing was essential.

I truly couldn?t have asked for a better trip!! My group was warm and friendly, our CEO Sony was intentional about supporting as many locals as possible with our visit, and it was a great mix of optional and included activities. The flexibility of doing what I wanted while also combining with the safety of having a group of other foreigners balanced out nicely. The price point was another great factor. I?d happily tour with G Adventures again!
