Description

The Main Cliffs hold some of the longest routes in the Sacred Cliffs. The rock is typical of the hill, and a slew of routes are still of mixed character. The short hike is well worth the investment for the quality of the routes and exposure on the longer ones.

Getting There

Hike South along the ridge to a point 100 ft or so beyond Pebble Beach. There is a nice point immediately prior to The Main Cliffs where you stand just above the canyon looking East over Boulder, a nice view and a popular spot for non-climbers, climbing starts on the right with a North Facing Crack.
