Semuc Champey is a beautiful series of terraces located in north eastern Guatemala. The river suddenly goes subterranean and disappears for a few hundred meters.
On top of the huge rock slab that the river dives under, are beautiful terraces of clear water. Water coming from forest streams has created these limestone terraces in the rock above the river. You can wade and swim in these clean, warm pools. If you sit on the edge and rest your feet in the water, small fish nibble at the dead skin on your feet. Considering the price that some people pay to have this done in urban settings, this is very cool.
For a birds eye view, you can take a hike up the mountain to an overlook above the terraces. The view of the blue waters is spectacular.
