The Caves are the second environment the player encounters. It takes the shape of a brown stone cave.

This environment introduces Pits and Spikes. The player cannot move over pits without The Ladder, items that give him flight, or bombing an adjacent Rock to fill the hole in.

Spikes hurt Isaac for one heart of damage, unless he has flight.
