About
Khao Sam Roi Yot National Park, meaning "Mountain of Three Hundred Peaks," protects Thailand's largest freshwater marsh and is one of the most spectacular natural areas near Hua Hin.
The park's main attraction is Phraya Nakhon Cave, one of Southeast Asia's most stunning caves. Inside, sunlight beams through a collapsed ceiling to illuminate the ornate Thai pavilion (sala) built for King Rama V's visit in 1890. The sight is particularly magical in the morning when the light is best.
Reaching the cave requires a 30-minute uphill hike through jungle terrain, but the views and the cave itself make it worthwhile. Wear good shoes and bring water—it can be hot and humid.
The park also features mangrove forests, limestone hills, beaches, and diverse wildlife including over 300 bird species, making it a paradise for nature lovers and photographers.
