Awesome hike, started counter clockwise, straight up first 1.3 Miles, then continued climb up to 2.7 Miles. It’s hard as described, if one starts clockwise then it’s less intense. Spectacular view of Oakland, San Francisco, Emeryville, Berkley, Richmond, Lafayette, and Moraga. Lot of wildflowers. 6.7 miles with elevation gain 1,667 feet.
