The Seven Teacups

The Seven Teacups trail, located near the town of Johnsondale, California, follows Dry Meadow Creek as it descends through a slick rock canyon containing a series of teacups, or pools, before emptying into the Kern River.

It is rated as a Class 3C canyon, meaning that it features water with a potentially strong current.
