Hill 88 is a 1,053-foot hilltop in the Marin Headlands. It towers over Rodeo Beach, with the Marin coast and ocean on one side, wilderness foothills on the other, and a pretty silhouette of Mount Tamalpais to the north, with San Francisco to the south. The pay-off views and natural beauty are a 10. The trip requires a climb that makes you feel that you've earned something special. That makes the trip a perfect mesh of beauty and ambition.
