Khao Sam Roi Yot National Park

Introduction: The Mountain of Three Hundred Peaks

Situated along the Gulf of Thailand in Prachuap Khiri Khan Province, approximately 50 kilometers south of Hua Hin, Khao Sam Roi Yot National Park is one of Thailand's most visually dramatic and ecologically diverse coastal reserves. Established in 1966 as Thailand's first coastal national park, its name translates to "The Mountain with Three Hundred Peaks," describing the majestic series of grey limestone karst mountains rising abruptly out of coastal marshes, beaches, and turquoise waters.

Spanning 98 square kilometers, the park is world-famous for the iconic **Phraya Nakhon Cave** and its golden royal pavilion, alongside extensive mangrove forests, prehistoric archaeological caves, and **Thung Sam Roi Yot**—Thailand's largest freshwater marshland.

Key Attractions & Natural Wonders

Khao Sam Roi Yot offers a captivating blend of royal history, deep prehistory, and wilderness landscapes:

1. Phraya Nakhon Cave & Kuha Kharuhat Pavilion

The park's ultimate landmark. A massive two-chambered limestone cavern with open sinkhole ceilings that allow sunlight to stream in. Inside sits the **Kuha Kharuhat Pavilion**, a golden four-gabled wooden pavilion constructed in 1890 for King Chulalongkorn (Rama V), which serves as the official symbol of Prachuap Khiri Khan Province.

2. Thung Sam Roi Yot Freshwater Marsh

Located on the western side of the park, this is Thailand's largest freshwater wetland. Featuring extensive wooden boardwalk trails winding over lotus-filled waters against the backdrop of jagged limestone peaks, it is a world-class birdwatching sanctuary for migratory waterfowl.

3. Khao Daeng Viewpoint & River Cruise

A rewarding 320-meter peak hike offering 360-degree panoramic vistas over limestone karst spires, shrimp farms, coastal beaches, and the Gulf of Thailand. Nearby, visitors can take a quiet longtail boat cruise down the Khao Daeng River through mangrove forests.

4. Prehistoric Archaeological Caves (Tham Din & Sai Cave)

The park's caverns preserve deep human history. **Tham Din Cave** made global headlines for the discovery of a 29,000-year-old child skeleton ("Pangpond")—Thailand's oldest human skeleton—alongside 3,000-year-old red ocher rock art depicting prehistoric hunters and wildlife.
