This is the wall across the back of the picnic area above the pools, with BBQs along its base. It is the first wall along to the right along the front-side of the Potrero.

Be very careful on this wall, especially on the upper pitches of any mulit-pitch routes, when the pools and picnic/BBQ area is busy. Any rock fall could hurt locals, including children, who will not be looking for or expecting rock fall. (In fact, it is probably best to not climb anything multi-pitch on this wall if the pools and picnicing is at all busy.)

Access issues inherited from El Potrero Chico

Most of the climbing here is in a State Park and there is no fee to enter. Please help maintain a clean environment in order to help maintain these privileges.


Walk up past the pools and BBQs to the obvious wall.

Grade Route

Climbs through heavy vegetation in this small corner at the far left side of Wonder wall. Has intermediate anchors for rapping with a 60 meter rope.

Shares first 3 bolts with Unknown1 and intermediate anchors. Then climbs up and right onto the face.

Two top-rope anchors used for introducing local kids to climbing.

"Best 5.8 in Potrero."

(Don't mistake the "Kiddie Korner" anchor just to the left as you climb for anything that is yours.)

FA: Dane Bass

Climb the thin crack just right of "Mr. Hanky", and shares anchor with it.

Super Sweet 5.10a

Climb the obvious crack and then over the bulge at the top.

FA: Dane Bass

Climb the crack on "Monkey Bizness", but angle rightwards to finish on "Halfway to Booty" rather than finishing up over the bulge.

This route climbs up just to the left of Evil Shenanigans. Climbs much easier, especially the second and third pitch compared to Evil.

FA: Magic Ed & Ann Ramsey

Great 3 Pitch climb on far right of the wall.

This runs very close to "Ramsey's Shenanigans"; don't wander onto it, if you want full value for the 2nd (11b) and 3rd (10c) pitches.

This route has 3 variations.
