Main image

Phu Hin Rong Kla National Park is a protected highland park in Thailand known for rugged sandstone formations, montane forest, and a significant role in recent Thai political history. The area preserves upland scenery and a network of trails and viewpoints.

The park contains distinctive rock cliffs, wooded plateaus and viewpoints that give broad outlooks over surrounding valleys and ridges. Trails lead to scenic overlooks, natural rock formations and waterfalls, and seasonal mist and cool temperatures are a draw for visitors.

During the late 20th century parts of this highland area were used as a base by the Communist Party of Thailand; later the terrain and forest were incorporated into a national park to protect the landscape and provide public access.

The park sits in Thailand’s uplands in the general Phetchabun region, covering highland areas that lie between several northern and central provinces.

  • Recent history: Notable for its Cold War-era history as a base area for the Communist Party of Thailand during the 1960s-1980s before being converted to protected public land.
  • Visiting tip: Best visited in the cool season, when mountain roads and viewpoints are most accessible and temperatures are lower than the lowlands.
