ถ้ำแม่อุสุ (Tham Mae Usu) is the underground course of the Usu river, which flows through the karst tower from the western side to the easter. The resurgence ner the village Mae U Su is also the entrance for the cave tour. Quite typical for Thail show caves, it gets a little rough. It's necessary to walk some distance through the river to reach the ascent to the fossil part of the cave. That the reason why it is not possible to visit the cave during the rainy season. The cave has a parking lot and a barbecue area in front.
The show cave entrance is 20 m wide and 5 m high in one side of an impressive sinkhole. A large streamway can be followed to a wooden ladder leading up into impressive fossil chambers which eventually lead back down to the resurgence entrances. All the water in the cave is very warm, about 30 °C, and is probably the result of geothermal heating.
