A series of kloofs filled with the sound of running water and wildness more usually associated with inaccessible and isolated areas, the Groendal Wilderness Area surrounds the Groendal dam, fed by the Swartkops River. The reserve offers both marked and unmarked trails that include the relatively easy 16 km Blindekloof trail that takes hikers to Crystal Cavern Pool, or a short 4 km circular trail to the picnic area that is good for families.
