Trek Doi Inthanon National Park & Pha Dok Siew Trail Trek All Fee

The Pha Dok Siew Nature Trail in Doi Inthanon National Park in Northern Thailand is a popular trekking destination that has recently undergone improvements. The trail is managed by the local Karen people and is one of two nature trails in the park. With the support of a grant and assistance from Chiang Mai University, the Karen people have built bridges, stairs, and railings using bamboo and wood to enhance the safety of the trail near the waterfall. They have also placed educational boards along the trail to provide information about the local flora and fauna.
