The Route 32 side entrance to Union Cave in HeartGold and SoulSilver

Union Cave (Japanese: つながりのどうくつ Bond Cave) is a location in Johto. The main cave divides Route 32 from Route 33, though several other exits in the basement levels of the cave lead to the Ruins of Alph. A wild Lapras can also be encountered deep in the cave every Friday after Morty has been defeated (as Surf is required to get to it).
