Fountainspring Cave

50 Pokémon can be caught at Fountainspring Cave in Sinnoh.

Fountainspring Caves are water-filled rocky hideaways within Sinnoh's Grand Underground, unlocked when the player receives the Explorer Kit from the Underground Man in Eterna City. Pokémon here wander the cave freely rather than hiding in grass, and Surfing across the water lets players approach Pokémon visible on its surface. Rocks larger than the player block direct paths and must be circled.
