Tham Matcha Pla Won Cave features a large natural pool of more than 400 square meters at the cave entrance. It is formed by an underground river system flowing through limestone layers of the Kaobantad mountain range, emerging as a crystal-clear emerald pool. The water circulates naturally throughout the year, allowing visitors to clearly see the rocky bottom and dense schools of fish. The highlight is the gathering of Hampala barb and local freshwater fish, creating the famous “whirling fish” phenomenon.

Geology and cave formation: The cave system was formed over millions of years by groundwater erosion in limestone rock, creating underground passages and cavities. Inside, there are stalactites and stalagmites still actively forming, showing ongoing natural geological processes.

Ecosystem and watershed forest: Located near Khao Pu–Khao Ya National Park and within Kaobantad Wildlife Sanctuary, this area is part of an important southern watershed forest. It is covered by dense tropical rainforest rich in biodiversity, serving as a habitat for wildlife and plant species and a natural water source for downstream communities.

Black limestone cliff landscape: In front of the cave stands a distinctive black limestone cliff, contrasting beautifully with the surrounding greenery, creating a unique and dramatic natural landscape.

“Whirling fish” phenomenon: The dense gathering of fish is caused by natural water currents, stable cool temperatures, and abundant ecosystem resources. This makes the site an excellent indicator of clean water quality and ecological balance.

Ecotourism value: The area is used as a nature learning site, ideal for relaxing, observing fish, enjoying the sound of flowing water, and studying biodiversity in the Kaobantad forest ecosystem. It is a destination combining tranquility, beauty, and natural wonder.
