D&D Wall is on the main cliff and pairs with Horror Movie Wall to form a narrow canyon (aka. Pitfiend Pit).
Tolkein Wall is the small portion of main cliff just outside of the canyon.
These walls provides most of the easier routes in the park, ranging 5.7 to 5.11a. They include excellent sustained face routes at 5.10c, 5.10d, and 5.11b/c. This is a great place to learn leading 5.7/5.8/5.9/5.10 with no runouts.
