Tham Phi Hua To

Tham Phi Hua To is a limestone cave in Than Bok Khorani National Park in Ao Luek Tai, Ao Luek District, Krabi Province, southern Thailand. Accessible only by boat through the Bor Thor mangrove waterways, it is notable for well-preserved prehistoric cave paintings estimated to be 2,000 to 3,000 years old. The cave features large chambers, stalactites and stalagmites, and colorful rock art depicting humans, animals and hands, making it an important archaeological and natural attraction.

Visitors reach the cave by longtail boat or kayak from Bor Thor pier through limestone karst and mangrove channels, then climb steps to the cave entrance. Inside, a large chamber with stalactites and stalagmites contains extensive prehistoric wall paintings in red, black and white pigments depicting human figures, hands, animals and geometric patterns. The site is undeveloped with natural cave floors, low lighting and interpretive signs. A local guide is typically required to explain the paintings and navigate the cave.

Tham Phi Hua To is an important archaeological site with prehistoric rock paintings dated to approximately 2,000-3,000 years ago, attributed to Neolithic period inhabitants. The paintings, executed in red, black and white pigments, depict human figures, animals, hands and symbols, and indicate early human settlement and ritual activity in southern Thailand. Archaeological finds including pottery shards, tools and human remains support its use as a shelter and ceremonial site.

The name Tham Phi Hua To translates as Big-Headed Ghost Cave, referring to a local legend of a large-headed spirit believed to inhabit the cave. The cave is respected locally as a cultural heritage site and is part of the Bor Thor cave system that holds spiritual and historical importance for communities in Ao Luek. The paintings are considered significant examples of southern Thailand's prehistoric art.
