Monument Peak has views that make all the elevation gain very much worth it! This peak is less-visited than its twin, Mission Peak. There are spectacular views of the entire South Bay and grasslands. The peak, like most, is very exposed so know the weather before you head out the door.

Mission Peak is a popular peak in Alameda County. The trail to the top is well signed and strenuous but it worth it for the great views at the top. A lot of the trail is exposed, so it's important to have enough water and sunblock.

The panoramic views from Sunol Peak make the strenuous hike to the top worthwhile. Sunol Peak offers stunning views of the Diablo Range, Mount Hamilton, Mission Peak, and on clear days, even downtown San Francisco and the Pacific Ocean. Keep in mind it can get quite windy up here, even in the summer a windbreaker is advised. Bring plenty of sunscreen as most of the trail is quite exposed.
