Glacial Cavern

28 Pokémon can be caught at Glacial Cavern in Sinnoh.

A snowy hideaway deep in Sinnoh's Grand Underground, Glacial Cavern opens up once the Underground Man in Eterna City provides the Explorer Kit. Wild Pokémon roam the icy floor in plain sight instead of lurking in grass. Spikes of ice and scattered rocks fill the large cavern, which also contains a lake that can be Surfed to reach Pokémon visible in the water; some formations tower over the player and must be bypassed.
