The Seneca Caverns is a cave in Rijon, located in the center of Seneca Cavefront. The player must enter through the caverns to get to the other side of the route.
The caverns are made up of many different floors, but there are only three maps: 1F (containing the exits to Seneca Cavefront), B1F, and B2F (containing all the other small caves and a couple of islands). All of the island and cave floors are reached by descending a ladder from B1F, except for one ladder on the right-hand side of 1F, which leads to the B2F map.

Pokémon[]
Because of how the maps work, the lists of wild pokémon are grouped into "1F", "B1F" and "Island/cave floors" rather than for each individual floor.
