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 went on the 12 day Thailand trip - absolutely amazing. Koh Phangan especially was so nice, and the temples in Bangkok and evening boat tour in Koh Phi Phi was amazing (especially seeing the bioluminescent plankton at night!). Michelle (my tour leader) was especially incredible, she made the trip so fun and was there for any worries I had. Big shout out to our local tour guide too, Nana, who was super funny and super interesting to learn about the local Thai culture. It was my first time doing a tour like this, and Ive already booked a second tour with intro next summer! All in all, incredible trip! Cannot recommend enough.

I went on the 18 day Thailand intro and had the trip of a lifetime! Everything from even before we arrived was very organised which led to a completely stress free trip. Our group leader Zoe was amazing, bringing such positive vibes from day 1, and provided complete support throughout the trip and for onward travel. Our local guide Aei-ki was fantastic and provided cultural knowledge as we went round. Would highly recommend Intro travel and this amazing country!

I just finished the 12 day intro trip in Thailand. It was the most incredible trip. I was originally booked onto 9 days but made some amazing friends and was having too much fun so had to extend. This is the best way to travel stress free, the organisation is great and the activities are so much fun. We had Ellie as our group leader and she was amazing. She was always keeping the vibes high and showing us her best dance moves. I would really recommend travelling with intro and will definately be using them again soon.

Joined the Cambodia Intro trip solo and can;t fault anything about the experience. The group leader (Izabela!!) was incredibly friendly, welcoming and communicative throughout the whole trip and prior. The country is extremely relaxed and the people are super welcoming, it hard to go anywhere without being greeted or waved at by the local children. Every experience was well organised and the guide - whether that be a local or the tour leader - was knowledgeable and open to questions. I couldn;t recommend Intro enough to anyone wanting to travel solo or with friends! °
