Still Water Cavern

80 Pokémon can be caught at Still Water Cavern in Sinnoh.

The Still-Water Cavern is a hideaway within Sinnoh's Grand Underground, available once the Underground Man in Eterna City hands over the Explorer Kit. Its Pokémon wander freely through the cave rather than appearing in tall grass. Rocky trails wind among trees, grass, and fallen logs, and the southern portion holds water that can be crossed by Surfing.
