Just 20km south of Palenque, Misol-Ha cascades approximately 35m into a wonderful wide pool surrounded by lush tropical vegetation. It’s a sublime place for a dip when the fall is not excessively pumped up by wet-season rains. A path behind the main fall leads into a cave, which allows you to experience the power of the water close up. Misol-Ha is 1.5km off Hwy 199 and the turnoff is signposted, and two separate ejidos (communal landholdings) charge admission (around M$30).
The downside is that the path can get crowded, thanks to the early morning tours from San Cristóbal.
