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.

What made this trip really special was how different each day felt. One day we were walking through old temples, the next we were sailing on a quiet bay. Vietnam was full of surprises. The people were friendly, the food was amazing, and every place had something new to offer. Ha Long Bay was a real highlight. The boat ride through those tall limestone rocks felt peaceful and looked like something from a movie. Even the meals on the boat were great! I also liked how we didn’t just rush from place to place. There was time to look around, take pictures, and enjoy it all. Hoi An was beautiful with all the lanterns, and Hue had some really interesting history. Our guide explained everything in a simple and fun way, which made it more enjoyable. Then we went to Singapore, and it felt like getting into the future. It was super clean and modern, but still full of culture. The Gardens by the Bay were stunning, especially at night. Everything on this tour ran butter smooth, the flights, the hotels, the transport. It was easy to relax and enjoy. Already thinking of booking a Korea tour. Really impressed by how they manage things!

Biking Saigon to Angkor Wat - May 2026

The Mekong, Southeast Asia’s longest river, is the lifeblood of southern Vietnam and Cambodia. Its floodplains harbor a cycling paradise, from the braided waterways and lush greenery of the Mekong Delta to the endless rice paddies and heritage sites of rural Cambodia. On this 9-day bike tour, we explore the lifeways, histories, and cuisines spanning the lower reaches of the Mekong as we connect the electrifying modern city of Saigon with the venerable ancient temples of Angkor. We meet in Ho Chi Minh City (a.k.a Saigon) and head south into the heart of the Mekong Delta, spending three days cycling on quiet backcountry roads in a serene world of coconut farms and rice fields. We rattle over small bridges or hop on local ferries to cross rivers. We also spend time on the water, delving into the aquatic commercial frenzy of Vietnam’s largest floating market at Cai Rang and cruising up the Mekong River on a speedboat to reach Cambodia’s capital, Phnom Penh. From here we head north, layering our tires with grit from the Kingdom’s notorious red-dirt roads, to reach the sleepy backwater town of Kampong Thom and the ancient, jungle-covered ruins of Sambor Prei Kuk. And finally we arrive in Siem Reap where, riding on paths perfect for mountain biking, we’ll explore the UNESCO World Heritage-listed, majestic temples of the once-glorious Khmer Empire, including, of course Angkor Wat, the world’s largest religious monument. The tour ends in Siem Reap. Join us on this captivating journey through the heart and soul of southern Vietnam and Cambodia! If you want to explore more of Cambodia and then continue onwards into Thailand, then join our Saigon to Bangkok by Bicycle tour. The first 8 days between Saigon and Siem Reap are identical to this trip, with a further 6 days subsequently leading to Bangkok, Thailand.

Japan´s Landscapes - May 2026

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.
