Khao Yai Thien, situated close to Namtakhong resevoir in Nakhon Ratchasima province was home of the Thailand Enduro Series Round 4 in 2017. Khao Yai Thien is just 3 hours from Bangkok, easily reached via Highway 1 North East to Saraburi and Highway 2 which heads to Nakhon Ratchasima city. As you drive past the town of Pak Chong Namtakhong will be on the left side so from here you have to look out carefully for the small road which turns off on the right heading up the mountain where the trails are located. There are numerous popular resorts making it an ideal place to stay a night or 2.

Special Stage 3 takes place higher up on the mountain than stages 1 and 2 and is a more technical stage with steep descents, large rocks to navigate and tight sections through the forest. The trail is just over 1km in length and requires a lot of concentration when cycling down at speed. The trail follows an access road which is useful for uplifts as the road is very steep to cycle up.
