Designated in 2023 as an IMTA International Mountain Hiking Tourism Model Route, this trail in northern Laos' Luang Prabang province connects the UNESCO World Heritage town of Luang Prabang with Nong Khiaw. Its core appeal is "pristine tropical mountain scenery + traditional Lao Buddhist culture," offering a classic experience of Southeast Asian slow travel and natural beauty. Its moderate difficulty also makes it popular for family hikes and cultural study trips.

The approximately 28km trail can be hiked in 2-3 days, with low difficulty and gentle elevation changes, mostly on earthen paths and stone steps. It winds through tropical monsoon forests with dense vegetation, ancient trees, and hanging vines. Summer offers cool streams for wading; winter is dry and cool, ideal for hiking. Key attractions include the Tham Kang Cave, accessible by boat, featuring stunning stalactites and stalagmites. The trail also passes traditional villages of Tai and Lao Loum ethnic groups, with preserved bamboo houses and Buddhist temples. Hikers can participate in traditional activities like rice pounding and weaving.

Services reflect Southeast Asian hospitality. Village homestays offer traditional Lao food like tom yum and sticky rice in bamboo tubes. Host families are warm and welcoming, allowing deep cultural immersion. Both Luang Prabang and Nong Khiaw have good transport and accommodation, connecting to other Lao tourist routes. As an IMTA route, multilingual signs, cultural information boards, and basic emergency equipment are in place. The best season is November to February, during Laos' cool, dry tourist season, offering a blend of natural beauty and vibrant cultural festivals.
