Mission Peak
About this peak
Mission Peak rises to 2,517 feet above Fremont on the southern arm of San Francisco Bay and offers a 360-degree panorama from San Jose to Mount Tamalpais, with the Sierra Nevada visible on clear days. The recommended Six-Pack route is the out-and-back Hidden Valley Trail from the Stanford Avenue Staging Area, about 6.2 miles with 1,992 feet of vertical gain. The route is almost entirely exposed, so carry plenty of water and start early, since weekends are crowded.

Hazards
The route is almost entirely exposed, so sun, heat, and UV are the main concerns; carry at least a liter of water, more in warm weather. Steep gravel sections can be slippery and a short rocky stretch near the summit needs careful footing. Cattle graze along the Hidden Valley Trail, so keep your distance. Weekends and holidays are very crowded, and the preserve closes at night with fines for being in the park after closing.
