People come to Pinnacles to hike, rock climb, watch and study wildlife, view wildflowers, and experience nature. Pinnacles offers solitude, challenge, and escape from urban development.

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.

During the summer, extreme temperatures can make hiking uncomfortable at best, and possibly dangerous for those who are unprepared. If you plan to visit Pinnacles during the months of July or August, please check the weather forecast and plan accordingly. Carrying and drinking at least a liter of water per hour per person is recommended during hot weather.
