Marine Cave

1 Pokémon can be caught at Marine Cave in Hoenn.

Marine Cave is an underwater cavern exclusive to Pokémon Emerald and the only place in that game where Kyogre can be caught. It has no fixed position: a man at the Weather Institute reveals which of four water routes is experiencing strange weather, marking its current location. If the player is too slow, the cave vanishes temporarily, Terra Cave appears instead, and Marine Cave later resurfaces somewhere new.
