The national park is divided by the rock formations into East and West Divisions, connected only by foot trails. The east side has shade and water, the west has high walls. The rock formations provide for spectacular pinnacles that attract rock climbers. The park features unusual talus caves that house at least 13 species of bats. Pinnacles is most often visited in spring or fall because of the intense heat during the summer. Park lands are prime habitat for prairie falcons, and are a release site for California condors that have been hatched in captivity.
