Overview

น้ำตกเหวสุวัต • Haew Suwat Waterfall (Nam Tok Haeo Suwat)

Haew Suwat is the most visited waterfall in Khao Yai National Park — a 20-25 meter plunge waterfall where the Lam Ta Khong stream cascades over an ancient volcanic rock ledge into a deep circular pool surrounded by tropical evergreen forest. The waterfall gained international fame as the filming location for the cliff-jump scene in Leonardo DiCaprio’s “The Beach” (2000).

Located within the Dong Phayayen-Khao Yai Forest Complex — a UNESCO World Heritage Site inscribed in 2005 — Haew Suwat sits at approximately 700-750 meters elevation within Thailand’s first national park (established 1962). At just 2.5-3 hours from Bangkok, it offers medical tourists one of Thailand’s most accessible encounters with pristine tropical forest. The upper viewpoint platform requires only a short paved walk from the car park, making it suitable even for visitors with limited mobility.

Important: Park fees, hours, and trail conditions are subject to change without notice. Verify current information at the official park website before your visit. Wildlife sightings cannot be guaranteed. Weather conditions and waterfall flow vary by season.

Why Haew Suwat is Special

UNESCO World Heritage Setting

Haew Suwat lies within the Dong Phayayen-Khao Yai Forest Complex, inscribed as a UNESCO World Heritage Site in 2005. This 6,155 sq km forest complex is the second-largest in Thailand and a critical wildlife corridor across four provinces.

Key conservation significance:

• 2,168 sq km of protected forest in Khao Yai alone
• 9 endemic species found only in the Dong Phayayen-Khao Yai complex
• UNESCO-monitored management and conservation programs
• Critically endangered Siamese crocodile population in the river system

Volcanic Geology

The waterfall flows over volcanic rock substrate — remnants of volcanic activity hundreds of millions of years ago. Along the Pha Kluai Mai – Haew Suwat trail, traces of ancient lava flow are visible during the dry season. A cave exists behind the water curtain, accessible only when water levels drop sufficiently (typically December-April).

Unique Gibbon Habitat

Khao Yai is the only place in the world where White-handed (Lar) gibbons and Pileated gibbons share overlapping territory and interbreed — a key criterion in the UNESCO World Heritage inscription. Both species can be heard calling in the forest canopy around Haew Suwat during early morning hours.

Natural Features & Ecology

Landscape

Haew Suwat is a plunge waterfall where the Lam Ta Khong stream drops over a volcanic rock cliff into a deep circular pool. The surrounding forest is tropical evergreen, with dense canopy providing heavy shade along access trails. Behind the falling water curtain, a cave becomes visible during dry season months.
