A long drive up Corral Canyon Road (your car gets a hike, too!) leads to an unveiling of rock formations weathered by centuries of ocean water. Both jagged cliff faces and smooth stone surfaces beckon hikers to explore. The walk is relatively easy; only about a half mile separates the parking lot from the hike's finale, a spiral of stones placed meticulously on the ground by some unseen cult, flanked by more weathered and warped rock formations. However, the rocks, being fun to climb, encourage hikers to play, explore, maybe eat lunch inside a cave (complete with cave painting). For those who are looking for a challenge, Bulldog Road stretches on for another 7.6 miles the other direction out and back, with an elevation gain of 1250 ft. Castro Crest is fun for both experienced hikers and those just looking for a quick, fun jaunt.
