Tham Hup Pa Tat
It is a valley located at Moo. 1, Tambon Pa O. Enter the same way as Khao Plara and it is 1 km. before Khao Plara. It is 50 kilometres from Mueang Uthai Thani. There is a cave which was discovered by Phrakhru SantiThammakoson (Luangpho Thongyot), the abbot of Wat Tham Thong. In 1979, Phrakhru climbed down in this valley and found a lot of Tat trees (ancient trees in the same species as palm trees). Therefore, he drilled the cave to open the entrance in 1984. Later, the Department of Forestry announced this place as a conserved area because of its amazing topography and rarely-found plants such as Tao Rang (fish tail palm), Plao, and Khatkhao Lek. Hup Pa Tat is under responsibility of the Tham Prathun Non-hunting Area. The path leading into Hup Khao Pa Tat is quite dark, but after walking not so long visitors will see a large hole above that the light shines through to Pa Tat below, creating the atmosphere of the evergreen forest with high humidity in the primitive world. The light can shine down on the ground only at noon because it is surrounded by steep limestone mountains. It is a shady place where it is possible to admire the nature.
