Hike south on the Chalone Peak Trail, uphill past Gertie's Pinnacle, about 10 minutes to a ridge trail that leads north towards the Yaks. This ridge trail is a better approach to Kasparek's and Yaks than the trail shown in the guidebook. Just south past this trail junction is an east-facing wall with a midway ledge. This is Cortadura Wall.
