“Hup Pa Tat” is located in Tambon Thung Nang Aom, Larnsak District, Uthai Thani. It falls under the jurisdiction of the Forest Wildlife Sanctuary Cave Protection Zone. It is a place filled with the peculiar beauty of nature. Hup Pa Tat has been declared by the Department of National Parks as a conservation area due to its unique geographical features, housing a variety of rare plant species such as rattan, dwarf bamboo, and wild jackfruit.
The structure of Hup Pa Tat resembles a large cave chamber filled with Tat trees and ancient, exotic plant species. It was discovered by Phra Khru Santi Thammakosol (Luang Pho Thong Yod), the abbot of Tham Thong Cave Temple, in the year 2522 B.E. During his exploration, he found dense Tat trees, a type of palm, which led him to drill into the cave and establish an entrance in the year 2527 B.E.
Situated in the Huay Asok stream area, Hup Pa Tat is a karst hill of the Pla Ra Mountain. It was originally a cave that later collapsed, transforming into a cavity or a depression in the mountain. Covering an area of approximately 2 acres, it resembles a primeval forest from the Jurassic period. The elevation ranges from 100 to 592 meters above sea level.
Indigenous animals include cliff swallows and elusive junglefowls. The highlight, however, is the Pink Dragon Millipede, found only during the late rainy season to early winter (around August to November). It is a rare discovery in Thailand and unique to Hup Pa Tat, reaching a length of about 7 centimeters when fully grown.
On the last day of the old year, admission is free, and on regular days, the entrance fee is 20 Baht per person. Visitors can borrow flashlights for free from the entrance staff. Before ascending the stairs to the cave entrance, there is a spacious and somewhat dark cave. Some tourists use the flashlights on their phones, but during the festive season with many people around, it may not be necessary. Walking through the cave is not extensive, about less than a hundred meters, leading to the cave’s exit, entering the world of darkness. After a short climb and descending a staircase, visitors can explore further.
