About
True intensive mountain route through Khun Sathan National Park in Nan. Long climbs, high ridgelines, deep forest, and layered mountain views. The full 100km loop traverses the entire mountain range with over 6,900m of climbing — one of the most demanding ultra courses in Thailand. Nan Old City, with its centuries-old temples and quiet riverside charm, is a short drive away.
