I had a great experience. The group was very nice and I had a great time. I enjoy traveling with group because it is fun to meet likeminded travelers and make new friends from all over the world, however majority of this group was retired couples. It seems like G Adventure is starting to be popular among different age groups and as a result it might not meet my travel needs. I would like an option like 18-30something for 30 to 50 age group in order for me to be excited to travel with G Adventure again.

I had the best time on the Northern Thailand 14-day tour. It was so relaxing, and I felt completely safe knowing that wherever our tour guide took us would be amazing. I loved supporting local communities and learning about Thai culture in such a personal and meaningful way through our guide. Some of the highlights for me were hiking to waterfalls, visiting temples, feeding and washing elephants, going river rafting, and so many other unforgettable experiences. My favorite part was hiking up to a small village in the mountains, meeting and getting to know wonderful people, and playing with local children. Our tour guide also suggested the best restaurants and bars. I loved traveling with so many new people, many of whom I now call friends. I’ve already recommended this tour to my sister, and I just hope she gets a tour guide as caring and organized as Smile (my tour guide). He shared personal stories that helped us understand the culture through his own experiences, and he was always patient and happy to answer our million questions. He made sure everyone was safe, whether it was looking after us when we were sick or making sure we got home safely after a night out. He was also incredibly accommodating when it came to any extra wishes or concerns. Smile was both a caring friend, opening up to us on a personal level, and a great leader who was organized and supportive in every way. He shared so much about the history and culture, making the experience truly meaningful. I’m so glad Smile was our tour guide and so glad I took this amazing tour.
