I did the 12 day tour of Vietnam and I cant recommend it enough! It was amazing to see so many different places (Hanoi, Ninh Binh, Hoi An, Ho Chi Minh). Our leader Lauren was brilliant, she is so helpful and knowledgeable about everywhere we visited. She was also just great fun! Cant wait to do another intro tour in the future.

The team made our trip to Vietnam so special! Everything was handled smoothly, and we felt really well taken care of the whole time. They were super flexible with our schedule and quick to respond whenever we had questions. We didn’t have to worry about a thing, just enjoyed the trip. Would definitely use them again!

There was a lot of activities and a balance of time to rest and meet people. The hotels were nice and the transport was always ready and arranged well. I like the visit to the dog sanctuary and the beautiful beaches although the weather did not always hold up.

Song is the best tour guide I have ever had! He was so funny! So caring looked after us all so well always had good recommendations for places to go! Organized extra activities that the group wanted to do out of the tour checked we all had safe travels after the tour and got back from gili t island with booked boats back to Canggu or wherever we might have been going, it was my friends birthday whilst I was on the tour with her and he helped me organize a cake for the last night! Honestly could not be happier what a genuinely amazing nice man! I honestly can’t say enough how good he was!

A very good travel agency that was able to help us put together this magnificent 14-day holiday in Vietnam. We really appreciated the guides, the walks away from the crowds and the recommended homestays. The agency was available throughout our stay and even allowed us to pick up a small oversight in a hotel further down the road. Thank you very much, Vietnam Tour!

I think G adventures is one of the best decisions I?ve ever made, leaving with a bit of heart ache that it?s over and I wish to see everyone again, go through G adventures again for a tour in a new location! Some of the most fun I think I?ve ever had, never experienced something like this before and I?m obsessed, combining my love for new things, food, and experiences and of course the most important part, people. thanks to G adventures I?ve found quite a few good eggs from this tour!
