Cliff Cave has three floors. The lower floor contains breakable rocks. However, they do not appear until the player has acquired the National Dex. Inside Cliff Cave, the player can either go up or down; each path contains its own perks. Going down and out from Cliff Cave leads the player to the sea; where the only tall grass on Route 47 can be accessed with Waterfall, and Embedded Tower can be accessed with Rock Climb. The upper path will take travelers to Route 48 and the Johto Safari Zone.
