The Seaside Cave (Japanese: 海辺の洞穴 Seaside Cave) is a cavern located between Route 21 and Undella Bay. It is accessible as soon as the player gets to Undella Town; however, Black Belt Rocky blocks the player from exploring the cave until they push Team Plasma out of Opelucid City. It is also the first area in the game where an HM is needed to proceed, as Surf is required to reach Seaside Cave via Route 21 or Undella Bay.

Geography

The cavern has two floors and three entrances. One is to Undella Bay, another to Route 21, and another goes to a separate area of Route 21, where the Plasma Frigate is found. The bottom floor has a Strength puzzle.
