There are a lot of trails and fire roads here to explore. There's no major climbing though the occasional steep, deeply rutted sections can be found. The network of trails consists mostly of rolling singletrack and fire roads. There are so many trails here that exploration is the only way to find them. There are at least 10 singletrack trails here that are some of the best trails in the region. These trails are extremely popular and well liked, but trail use is still relatively light.
How to get there:
From San Francisco, go East on HWY 80 to Vallejo. Turn left onto HWY 37 to HWY29 North. At the fork on 29, turn right to Napa and Lake Berryessa. This road is the Siverado Trail. Follow this and it will rejoin HWY 29. You can stay on 29 the whole way if you want, but it will take longer. Follow 29 over Mt. St. Helena and to Middletown. In Middletown, turn left onto HWY 75. Follow 75 for six miles to Cobb. About a mile after Cobb turn right into Boggs Mountain at the fire station sign.
Camping is available and be careful during hunting season.
