You have to hike or ride horseback to see this magnificent 9,737-acre parkland, accessible only by way of the Ohlone Wilderness Trail. Its centerpiece is 3,817-foot Rose Peak, just 32 feet lower than Mount Diablo. Surrounding Rose Peak are grassy ridges, profusely flowered in season. The abundance of wildlife includes golden eagles, mountain lions, and tule elk.
To Reach The Park
The region is home to very few people, but it shelters abundant wildlife. Creatures not often seen near metropolitan areas live in these lands, including the endangered bald eagle, mountain lions, bobcats, deer, and a herd of Tule Elk.
The landscape includes oak and bay woodlands, grassy uplands carpeted with springtime wildflowers, and wilderness ridges and peaks.
Hiking and Horseback Riding
The remote and beautiful wilderness areas of the Ohlone Wilderness are accessible only through the Ohlone Wilderness Trail. The Ohlone Trail traverses 28 miles of mountains and canyons in southern Alameda County and is open to hikers and equestrians. Trail bicycles and motor vehicles are not permitted.
The Ohlone Trail passes through the Ohlone Wilderness and three regional parks: Mission Peak Regional Preserve in Fremont, Sunol Regional Wilderness near Pleasanton and south of Sunol, and Del Valle Regional Park. It also passes through two watershed areas leased from the San Francisco Water Department.
It is very important to stay on the trail corridor in these leased areas and obey directional signs along the way. Trespassing off-trail into non-leased water department lands may result in citation and may jeopardize future public use of the leased lands.
Ohlone Wilderness Regional Trail Hiking Permit (REQUIRED)
The Ohlone Wilderness Regional Trail Hiking Permit/Map is required for both day use and camping/backpacking for each person, ages 12 and over. The permit is valid for one year from the date of purchase. LEARN MORE AND PURCHASE ONLINE.
A separate camping reservation is required if you plan on staying overnight at one of the designated campsites along the Ohlone Wilderness Trail. Camping reservations must be made at least TWO days in advance by calling the Reservations Department at 1-888-327-2757, option 2 (10:00am-3:00pm Pacific time, Monday-Friday except holidays).
Separate camping reservations can also be made at Del Valle Regional Park (outside of the Ohlone Wilderness at the north end of the Ohlone Trail).
