This was my first solo trip ever and it was the best trip that I’ve ever been on. From having the best group of girls to the best tour guide ever— it has truly been an amazing experience that I’m not ready to have it end. Ming is the best tour guide and has made this trip so seamless and enjoyable for all of us. She’s prepared, always there to help us and gives the best recommendations. She truly would give the shirt off of her back for any of us and my first solo trip wouldn’t have been this much fun with any other tour guide. I can’t say enough good things about Ming truly. The sweetest soul ever and I’m so happy to have had her as my guide this trip. 🤍

My first solo trip to Southeast Asia was incredible. Our CEOs, Tew and Sam, were exceptionally caring, organized, and genuine. They fostered a welcoming atmosphere that made it easy for everyone to form friendships and explore the stunning countries. I truly value the meaningful connections I made—thank you so much for these unforgettable memories!

Journeys: Iconic Thailand - May 2026

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 had Sea as my tour guide and she has been by far the best tour guide I have ever had!!!! I’ve been on multiple tours and she was so incredible and lovely, she made the trip so fun with her bright bubbly, funny and kind personality!! She made sure to include everyone and remember things about each person. She was so caring and went above and beyond even after we were done the tour, she helped us organize our transfers to our next destination and made sure we were safe every step of the way. On the tour she was so nice and got so many good photos for us and gave us so much information about Thailand and our itinerary. She was also an amazing friend that we met along the way, she helped when I wasn’t feeling well and got everyone medication when we needed it. She always brought amazing energy to our days and it was so nice to have her as a tour guide. I would love to have her for every tour if I could!!! Thank you so much Sea for everything you did.

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.

The. Itinerary was comprehensive and diverse.. It covered the many cultural and historical aspects of Thailand but also included many experiences that were very entertaining as well educational all of which helped to understand and value the rich culture of the country. We loved our guide , having traveled extensively, she was by far the best combination of organization, fraternity, education, gastronomy, cultural immersion and fun, fun, fun! Best guide in an absolutely treasure of a country.

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!
