A full-day trek from Bangkok into Khao Yai National Park to visit Haew Narok and Haew Suwat waterfalls, wildlife-rich reservoirs, and panoramic viewpoints. Expect jungle trails, river-carved cliffs, and the best waterfall flow during the rainy season (June–October).
More ways to explore the area's outdoor wonders
You step off the minivan into humid forest air—leaves clack overhead and the park’s mountain spine looms beyond the road. The trail to Haew Narok begins as a ribbon of packed earth and roots, then tightens into jungle that seems to breathe. Haew Narok answers with a thunderous drop; water once carved the cliff into a ragged mouth that dares you to approach the viewpoint. Later, Haew Suwat offers a quieter stage: broad slabs and shade where the film crowd once gathered, now claimed by birds and moss.
