From the hotel, we head out of town, cycling for the first 25km on a relatively flat road through terraced rice paddy fields. Passing through minority villages, we cycle the next 25km up winding roads into the vast limestone mountain range with its perpendicular rock walls, climbing 800m towards the mountain road past “Heaven Gate 1”. As we pass through mountain villages, sometimes covered by clouds, we will receive a friendly greeting from the local communities. From the pass, we can look down at amazing views, including the famous vista of the Tam Son Valley with the ‘Twin Hills, and can spy on Quan Ba town, Have lunch on the summit, and enjoy the picturesque scenery. After lunch, we set off our bike to descend to the river and ride along to Gam River until we meet another pass again. We cycle uphill for the first few km before a descent of around 10km and then relatively flat terrain for the next 10km. It’s a challenging up-and-down terrain to an altitude of 1.025m before we finally descend for the last 15km into Yen Minh. We will have the chance to see the traditional homes of the local hill tribes. The communities in this area are Chinese.
