This sacred Fish cave is situated at Ban Huai Pha, 17 kilometers from Mae Hong Son town. The name is a bit misleading. There’s no cave that you can really go into. The park surrounds a place where a small stream emerges from the rock face of a hill. A special feature is the hollow cave filled with hundreds of Phluang fish, or carp soro, which you can see through an opening in the rock of 2 square meters. Some of these fishes are 1 meter long. They are fed with vegetables and insects by the locals and always stay in the cave. The fish seem to like to cool water of the cave, and you can see them ‘queuing up’ to get in. There’s another small opening a few steps up that allows you to look down into the cavern, which appears to be filled with the fish.
The park is a cool shady place with forests of trees lining the cool stream flowing out of the hill. Beyond the stream, near the park entrance, is a large open space suitable for pitching a tent. There are also a number of food stalls and restaurants around the entrance. While the Fish Cave itself is not a really spectacular sight, the cool environment and ample amenities make it a very pleasant spot to plan a lazy afternoon.
