I did this in a previous paragraph. All in all I had a wonderful time despite the two group members that were an annoyance to the rest of us.

Incredible destinations, delicious cuisine, and unforgettable experiences made this tour exceptional. However, what truly set it apart was our CEO guide, Apple. Her professionalism, extensive knowledge, organization, humor, and passion for her role enhanced every moment. She handled challenges fearlessly and, above all, ensured the safety of every traveler. I would highly recommend G Adventures to friends and family, and Apple as the guide. Thank you, Apple, for an amazing journey!

Overall, I was truly impressed by how earth and human conscious G Adventures is. This unique focus really sets your program apart from others and makes me proud to support you now and in the future. I had the pleasure of joining my first G adventure group, accompanied by such a wonderful group of people and an excellent CEO Min and incredible local guides: Jill, Addi and Seng. Earth and human-centered tourism are often afterthoughts, so it was a pleasant surprise to see these values woven seamlessly throughout the trip, from the villages we visited to the local restaurants we supported. This thoughtful approach made the experience not only enjoyable but also deeply meaningful.

This trip was everything we could have wished for and more. We would recommend this to anyone who wants a brilliant balance between seeing and doing! Thank you to our incredible tour guide Hoan who ensured we felt safe, relaxed and comfortable throughout the duration of the trip!

Even though I was the only person on this trip, I cannot thank Explore highly enough for the excellent liaison with the local partners to ensure I had a safe and seamless trip. Although most days were spent in Cambodia, it was interesting having some time in Thailand and Vietnam as well. I would highly recommend this trip.

Our meditative trip takes you along the Mekong River on board a ship combining charm and colonial-style comfort.
