Bighorn Mating Grotto Rock Climbing

Walk north from Uncle Willie's parking area (just past Barker Dam parking on the remaining portion of the older dirt road). Walk past Fire Me A Burger Rock and Freak Brother's into north Wonderland Wash. Continue keeping west of Disneyland Dome and east of the Astro Domes out the north end of the wash and keep your eyes peeled for Diarrhea Dome. When you find it head for the west end of Diarrhea Dome and scramble up 3rd class-ish terrain (several possibilities) into the Grotto which is tucked in on it's west end.

Can be hard to find, use Vogel's maps and/or be familiar with the area. It takes 45 mins if you know where you're going, but can take a lot longer if you don't. It's a small/deep alcove with 100+ foot routes that's hard to see from a distance. If you hear people and you think you're close it's probably correct 'cause it's by far the most popular attraction in the area.
