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.

Hello, following our recent trip in Japan.
I would like to pass on the following feedback. Firstly, I would like to congratulate all of your staff for their professional, helpful, informative commentaries for our daily activities. Although there were relatively small groups of English speaking guests on the tour we were always included and I was most impressed with the overall set up. This was our first group/tour style holiday and I would definitely look at booking other trips in the future based on this experience.
The only negative was one guide whos comprehension of English was only just adequate, as when presented with any questions he was unable to give succinct answers, and often just glossed over explanations which fell short overall. Conversely another guide David Muñoz was absolutely brilliant, his English speaking and comprehension was excellent, he managed his section of the tour with ease, engaging all guests equally, the knowledge he was able to pass on far surpassed the other guides and for this reason I am writing this message with the hope he will be acknowledged for an outstanding job. He was detailed with sharing knowledge and made the whole group comfortable with one another. All meals and hotels were fantastic, until we travelled with Maria, I and many others in the group felt that the standard of meals provided with the exception of the Roykan and Monastery at Mount Koya were sub standard in comparison to that which wed been provided prior. Excellent experience overall, manager/supervisor should review restaurant locations offering for final part of trip, acknowledge outstanding staff performance and address staff whose comprehension of English was not of a great standard.
The variation of locations and sights was fabulous. Very well thought out itinerary, highly reccomend.

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.
