Thung Sam Roi Yot Wetlands

Introduction: Thailand's Premier Freshwater Marsh Sanctuary

Situated on the northwestern edge of Khao Sam Roi Yot National Park in Prachuap Khiri Khan Province, approximately 60 kilometers south of Hua Hin, the Thung Sam Roi Yot Wetlands (also known as Bueng Bua Nature Education Centre) encompass Thailand's largest freshwater marshland. Covering roughly 37% of the national park's total land area (over 4,300 hectares), this expansive wetland ecosystem is internationally recognized as a Ramsar Site for its exceptional ecological importance and rich aquatic biodiversity.

Set against a dramatic backdrop of towering grey limestone karst peaks rising abruptly out of calm waters, lotus ponds, and extensive reed beds, Thung Sam Roi Yot is world-famous as a paradise for birdwatchers, wildlife photographers, and nature lovers seeking peaceful walking trails away from crowded coastal beaches.

Key Attractions & Wetland Highlights

The marshland features unique natural highlights and specialized visitor infrastructure designed for unobtrusive wildlife observation:

1. The Bueng Bua Boardwalk

The centerpiece attraction is an elevated wooden boardwalk that winds roughly 1.2 kilometers directly over the freshwater marsh. Flanked by tall reeds, blooming water lilies, and lotus blossoms, the boardwalk features covered rest pavilions and benches for soaking in panoramic views of the water reflecting the surrounding limestone mountain range.

2. High-Elevation Observation Tower

Located along the boardwalk route, an 8-meter-high timber observation tower delivers sweeping 360-degree aerial views over the vast reed beds, open water channels, and mountain peaks—offering an ideal vantage point for spotting distant waterfowl.

3. World-Class Birdwatching Refuge

The marsh supports over 300 bird species, including both resident species and migratory waterfowl that arrive during winter months. Notable species spotted along the boardwalk include grey-headed swamphens, purple herons, bronze-winged jacanas, kingfishers, oriental darters, and the elusive fishing cat in deeper marsh zones.

4. Punt Boat Eco-Tours

Visitors can charter traditional flat-bottom punt boats guided by local park rangers to navigate deeper open water channels and lily pads where boardwalks do not reach.
