Yong Waterfall National Park

Yong Waterfall drops through a series of limestone tiers — commonly counted at around seven — inside its own national park in Thung Song district, on the southern flank of the Khao Luang mountain range in Nakhon Si Thammarat province. It’s a DNP-managed park with a real entrance fee: 100 THB for foreign adults (50 THB for children), 20 THB for Thai adults (10 THB for children), open daily 08:00-16:30. This is a separate park from Khao Luang National Park to the north — same mountain system, different management area, about 30km apart.

Trails through the surrounding rainforest link the tiers, climbing gradually from car park to upper falls. The lower pools are the swimming draw — clear, cool water pooling below the first couple of drops, shallow enough for a casual dip rather than serious swimming. Higher up, the trail narrows and gets rockier, rewarding the effort with quieter pools and a better sense of the forest closing in around you. Hornbills and other forest birds are reported in the canopy, and the wet limestone underfoot means footing needs attention on the approach to each tier, particularly after rain.

Watch out: The rock around the falls is limestone, not the coarse volcanic stone some Thai waterfalls have — it’s smoother and gets genuinely slick when wet. Move carefully near the pool edges, especially barefoot.

The park sees a fraction of the visitors that hit Erawan or Bua Tong-style waterfalls further north, which is the appeal for anyone tired of queueing for a photo spot. Basic facilities — restrooms, a small visitor point — sit near the entrance, but don’t expect food vendors or a developed base area; this is a working DNP park, not a tourist complex.

Insider Tip: Flow is strongest June through November, in line with the region’s rainy season, but the trail also gets muddier and the rock slicker in that window — trade-off between water volume and easy footing.

For the higher-altitude side of the same mountain range, Khao Luang National Park covers the 1,835m summit trek that starts from Ban Khiriwong village, about 30km north of here. Both fall within Nakhon Si Thammarat province.
