The Mileski Wall
Tenasi fresh out of his cave, flashing 5.12.
This excellent steep wall offers quality 11's and 12's on a smooth, vertical wall and is definitely worth the 25 minute hike up from the canyon. This is as good as Potrero climbing gets!
The classic Mother Superior.
Recommended Routes
Mother Superior 12a. The first Potrero 12 for many, due to its sustained but not cruxy nature and closely spaced bolts. The top-out on slightly overhanging, hueco-riddled grey rock is classic.

Mr. Big. 12b, 40m. Long and continuous with technical moves.
