People come to Pinnacles to hike, rock climb, watch and study wildlife, view wildflowers, and experience nature. Pinnacles offers solitude, challenge, and escape from the urban interface of both the San Francisco and Monterey Bay areas. Unlike many national parks, Pinnacles is most popular in the cooler months. During the spring, when the grasses are green and a variety of wildflowers can be seen along any trail, hiking is at its best. Fall and winter are also excellent times to visit.
