Today is a challenge for us to cross Truong Son Mountain Ranges and west Ho Chi Minh trails along the border with Laos. It is a too long way for us to enjoy our day adventure biking. So there will be 2 sections; a 35 km ride in the morning and a 35 km ride in the afternoon. We will relax on a vehicle transfer at noontime before and after lunch. It is also good timing to avoid many serious hills. After early breakfast, we jump back on the bikes and start a cycling adventure from the hotel. Explore many breathtaking views; limestone mountains, fascinating valleys, spectacular mountain scenery, ancient rainforests, and a small village. There is big picnic lunch rather than lunch locally. The afternoon ride is pleasant biking and allows you to bike downhills more than up when the weather temperature is calm down. View the farm, green farmland, lakes and past many Ethnic villages before the hotel to check-in—diner in the town of Khe Sanh with the team.
