We had a fantastic trip. Bamba gave us all the information we needed and the guides during the tours were great. We loved Vietnamese countryside, the floating market and the tour to the Cu Chi tunnels was very interesting. Highly recommended, you won't be disappointed.

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!

Take on a 12-day adventure full of Cambodian highlights, that takes you beyond the usual tourist route. Discover the laidback charm of riverside Kampot, call into the ancient temples at Angkor near Siem Reap, get a taste of Khmer hospitality with a village homestay in Chambok and reflect on Cambodia's tragic history at the sobering sites of Phnom Penh. With an expert leader bringing the history to life and plenty of freedom to explore at your own pace – this adventure is much more than a transitional trip through one of Southeast Asia’s most captivating countries.

Go deep into these two great countries as you get into riverside vibes, cool waterside bars, as well as taking in jaw-dropping sunrises at the likes of un-missable Angkor Wat. Take part in an alms ceremony in Luang Prabang and hit the streets for a bike tour...each day is different, and downright amazing.

Overall this was a great tour that I would certainly recommend taking! Although I certainly could’ve stayed at some of our stops longer, I never felt rushed and felt the tour did a great job of giving enough time to see most if not all of what I wanted to. This was a great introduction to Southeast Asia and this trip has certainly inspired me to come back for a longer visit. The guides and group were fantastic and always had me smiling and laughing.
