This group of caves in the Chiang Dao region north of Chiang Mai is full of massive limestone and crystal formations. Though there are many caverns at the base of the Doi Chiang Dao mountain range here, these five in particular are interconnected and open to explore, with impressive stalagmites and stalactites hanging and growing from the ceilings and floors.
Buddha images on the walls of the caves are evidence of their use as shrines and meditation sites. Estimated to run seven miles (12 km) deep, the first two caves are well-lit, but you’ll need a guide and a lantern or flashlight to access the others. Seasonally, an underground river flows through some of the caves, along with many other natural wonders and cultural sights to be discovered and explored.

Chiang Do is located 45 minutes north of Chiang Mai on Highway 107. Once you reach the small town of Chiang Dao, look for signs that will direct you toward Doi Chiang Dao; the entrance to the caves is about three miles off the main highway. Admission costs 40 Thai Baht, and a guide with a lantern will cost about 100 Baht.
