A group of 8 of us hired 5 bikes and had one person on the back of our tour guide, Thanh, to do the Hai van Pass. Unfortunately it rained all day and we were in a cloud at the top of the mountain so we missed out on some of the spectacular scenery. However we all had a fantastic time despite this. The views we could see were fantastic and the ride itself was fun but not suitable for beginner riders as there are lots of sharp turns. Thanh was a great guide. He gave us plenty of time to explore the marble mountains, he was good at waiting to see if everyone in the group was keeping up, he drove at a good pace for confident riders and he took us out to some good bars once we reached Hue! The bikes, route and guide were all excellent. I would definitely recommend this company!
