Mae Usu Cave
(ถ้ำแม่อุสุ)
Tak
Mae Usu Cave is quite spacious with a high ceiling. The air is not too stuffy and it is not too dark either so there should not be any problem. You first need to prepare to get wet however since you need to wade through the stream from the mouth of the cave. Assistants of the national park are ready to guide you and the path inside is not too rough to walk. Inside, with the temperature at 16-17 degree Celsius, you will find three big limestone halls. Mae Usu stream 450 meters in length, rushes to the cavern in the southeast and bends to Moei River at the back. The cave entrance is twenty meters wide and six meters tall and is amazingly decorated with wonderful stalagmites and stalactites. The most superb time to visit the cave is at midday when the sunlight creeps in from the crater and reflects the most amazing shimmering walls. The best time to visit is summer and winter since the water level in the cave is not too high.

You can take a short trip of four hundred meters and visit two halls. This takes about thirty minutes round trip. Another trip will lead to a farther path and takes about one hour. 

Mae Usu Cave is located on the magnificent Mae Sot, Mae Sariang Highway No. 1085 at Km. 95-96.

Getting there: Take Highway No.105 and take a turn at Km-13-14 to Baan Bae Gued Sam Tha. Go turther 8 kilometers.
