You are much more than Angkor Wat, which brought me there in the first place. The history, culture & people made it truly a special experience. Thank you, Cambodia!

There is no better way to see a country than to ride it. This average daily distance is ideal for anyone. Even the most unfit one in our group who struggled a little, (just a little), on day one, coped admirably overall. Book it, you will not be disappointed.

What an amazing experience!! We worked with the tour agent for over a year to plan our vacation and it couldn’t have turned out more perfect! Tracey listened to all over our hopes and interests, and delivered an itinerary that ended up being a dream vacation! We spent 2 weeks exploring Vietnam, Cambodia and Thailand with our family of 5 and the guides we had in each city were wonderful, knowledgeable, and felt like our friends just showing us around their country. We will absolutely go through them again when we find time to explore more of Asia!

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!
