Overview:
Tolman Peak (997 ft. elevation) is located at the southeast side of Garin / Dry Creek Pioneer Park, which is part of East Bay Regional Park System. This site was also famous for a plane (MD DC-6B) crash in 1951. This 5 miles round-trip hike takes you from the park's Tamarack entrance to the peak and back. It starts with easy uphill hike , several creek crossings until a moderate uphill climb to Tolman Peak. After the peak, it leads you into a well-shaded trail in the oak woods, completes the loop around the hill and then takes the same way back to the trailhead. This is a great hike for people looking for solitude and great scenic views on the east bay. The best season to hike is early summer.
