Did you know that you can create an account to record, track and share your climbing ascents? Thousands of climbers are already doing this.


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.

Ethic inherited from Nuevo León

Please don´t litter, some crags like LaHuasteca are a little runout, but thats how they were set, please avoid adding bolts. Rebolting efforts are much apreciated, just send a heads up to the local climbing comunity for safety reasons.

The first two climbs aren't truly on the "Wonder Wall", but around the corner to the left, facing into the main canyon.

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 Alley Cat and intermediate anchors. Then climbs up and right onto the face.

Two dihedrals, the right most now bolted, up to an anchor.

Originally used for belaying local kids to introduce them to climbing.

"Best 5.8 in Potrero." according to Dane's guidebook.

First climb right of the dihedrals, goes past an intermediate anchor after 5 bolts.

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

Starts up thin slab above the large flake leaning against the wall.

Starts 5ft (2m) right of the large flake leaning against the wall, and angles leftward after the first couple of bolts.

FA: Dane Bass & Ralph Vega

Starts 10ft (3m) right of the big flake that is leaning against the wall. Takes the left line of bolts at the old iron ring bolt.

FA: Dane Bass & Rick Ross

Starts about the same as "The Great Baldini", but branches right at the old ring bolt.

FA: Ralph Vega & Prentess Berry

Starts right behind a concrete picnic BBQ/table.

Be careful at the finish (last bolt) to stay right, else you'll finish on the anchors of "Redheaded Stepchild".

Stay out of black streak for 10d grade.

FA: Dane Bass & Rick Ross

Lovely route. Goes up for 5 bolts, then angles leftward.

1 5.9
2 5.9

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

1 5.8
2 5.11b
3 5.10c

Great 3 Pitch climb on far right of the wall.
