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!

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.
