Thong Pha Phum National Park

The land was part of the Pilok mining area from 1940 until the mines shut after the 1985 tin-price crash. Conservation planning in the Western Forest Complex began in 1991, and it was declared Thailand's 114th national park on 23 December 2009. Its forests range from dry evergreen to hill evergreen and mixed deciduous, with about 149 bird species including the great hornbill, and wild elephants.

Jok Kradin Falls is a single drop of about 30–34 m into a 3–4 m-deep pool, 300 m from the car park and 5–7 km from E-Thong; swimming is possible in the dry season. In July 2026 flash floods hit it and the park warned against swimming. Note that Huai Mae Khamin Falls is not in this park but in Khuean Srinagarindra National Park.

Khao Chang Phueak, 1,249 m, is the park's highest point: an 8 km trail each way, 4–6 hours, camping on the summit over two days and one night, with a knife-edge ridge. It takes 60 people a day, aged 13–70; foam, alcohol, pets and single-use plastic are banned. It opens only November–January: the 2026/27 season runs 1 November 2026 to 31 January 2027, booked through a Google Form posted on the park's Facebook page, with the first round opening on 16 October 2026 at 10:00.

Fees: Thai adults 40, children 20; foreigners 200/100; cars 30 baht. The falls open 08:00–17:00. Route 3272 has more than 300 curves and no fuel stations on the upper stretch, so fill up in town; parts have no phone signal, and wild elephants may be on the road. The park had about 123,285 visitors in 2024. Contact it via its Facebook page or on 034-510-979.
