About Cap Rock

Cap Rock is the small distinctive roadside formation at the Keys View turnoff — cap-shaped block sitting on a larger dome, immediately visible from the pull-off. A short-approach venue for warm-up and top-rope sessions, mostly in the 5.6–5.10 range. The picnic area makes it a family-friendly stop and it's on the standard park loop — first climbing formation many first-timers actually touch.
