Hup Pa Tat, Lan Sak District,
Uthai Thani Province

Walking through a long pitch-black stalactite Hup Pa Tat cave, where a flashlight is needed, you will feel like you have just made a journey back to the Jurassic Era once reaching the other side of the cave. It is incredible that the dark cave can lead you to this gigantic chamber of tropical evergreen forest with plenty of Arenga pinnata along the way (Arenga pinnata is prehistoric plant in the same family as palm trees). Hup Pa Tat is abundant with a variety of uncommon and rare plants; such as, Chukrasia velutina and strangely-shaped banyan trees. Detailed information of the plants is provided.
Roaming around the valley is considered a distinctive pleasant experience. Surrounded by limestone mountains, only limited sunlight shines in during the day. As a result, the area is humidified, making the weather perfect for you to enjoy a nice walk around, and appreciate the tropical trees and the chirping of various kinds of birds.
Walking along the 700 m path, you will find many animal footprints like those of deer, bulls, bears, boars and you can even see tigers’ claw marks on the trees. A wild boar might come out to greet you. If you are lucky, you will see rare animals like elongated tortoises and shocking pink dragon millipede, recently discovered in 2007 in this fascinating Hup Pa Tat.
