I would start ranting for hours. This trip was truly meaningful as it had so many layers. From enjoying the beach to learning about the sad history and reality of Cambodian "politics", it was a rollercoaster of emotions. I also think that it was the mix of our group combined with our best CEO Dolla, that made the trip so fruitful.

I had an amazing time traveling with G Adventures and would highly recommend it to anyone looking for a well-organized and unique group tour. What made this trip so special was the perfect balance between visiting well-known highlights and discovering hidden gems. G Adventures not only takes you to the iconic (and stunning!) tourist spots, but also brings you to small local communities you might otherwise miss if you were traveling independently. These visits offer a deeper understanding of the country and its people, while directly supporting the local economy — whether through cooking workshops, crafting or purchasing handmade jewelry, or other fun activities. They also work with local guides, which really adds an extra layer of insight and authenticity to the experience. Another big plus was how easy everything was: transportation, accommodations, and the overall itinerary were all taken care of. All you really had to do was choose your own lunches and dinners, pick any extra activities, and enjoy the ride. Our guide was fantastic — super enthusiastic, caring, and full of positive energy. And I was lucky to be part of a great group of fellow travelers too! All in all, I look back on this trip with a big smile, and I’d book with G Adventures again in a heartbeat.

This was a trip of a lifetime! Our trip manger always went above and beyond for our group and ensured everything ran smoothly. There was a great mix of culture, history, fun and great food! The people on this trip made it even more special. Despite many days in temple wear with the heat, this will be a trip hard to match. The jungle rafts in Thailand and slow boat in Laos were definitely a highlight.
