This is the farthest section of cliff at Lost Wall and consequently the least developed. The cliffline is more continuous and averages 80' in height, with a variety of steep trad climbs ranging from moderate to very hard. New routes are being added all the time by southern hardmen like Shannon Stegg and Jim Corbett. Because of the lack of traffic, routes in the Netherworld can be dirty and/or vegetated.
The Netherworld can be reached either by continuing past the end of the Prehistoric Wall, or by driving to a pullout above the main parking lot and following a vague trail down a rocky gully to join the cliffline trail at marker #6.
