Namtok Than Thip Forest Park

Namtok Than Thip is a 26-metre single-tier waterfall in a forest park near Lom Sak, Phetchabun — administered as part of the Khao Kho National Park unit, though it’s officially classified as a forest park rather than a national park in its own right. Entry is free, and the falls run year-round, peaking during and just after the rainy season from July to November.

The main cascade is a single drop into a pool with a sandy bottom, where wading is popular — the deeper plunge pool itself calls for more caution rather than treating it as a casual swimming spot. If you want the tiered, stepped look often associated with Thai waterfalls, a separate stepped section elsewhere in the park delivers that instead, with around ten smaller drops over rock formations. The forest park spans roughly 8,750 rai across two reserve areas and includes other named features along its trails — a rapids area, a fig-tree and rock formation, and a resting spot with natural pools — for visitors who want to walk further than the main falls.

Trails to the waterfall run through mixed forest that gets slippery after rain, so footwear with grip matters more here than in a paved park. Crowds are thin compared with Thailand’s better-known falls, which is part of the appeal if you’re after a quieter stop rather than a queue for photos. If you’re touring Phetchabun’s waterfalls, Sridit Waterfall and Tat Yai Waterfall are both within reach for comparison.

Watch out: There’s an unrelated waterfall that also goes by “Namtok Than Thip” in Sangkhom, Nong Khai — over 300 km from this one. If a review or photo mentions Nong Khai, it isn’t describing this park.

Insider Tip: Skip the main falls’ plunge pool if you want a safe wade — the sandy-bottomed shallows near the base are the better bet, and the stepped section elsewhere in the park is worth the extra walk if you want photos with visible multiple tiers.
