Tennessee Valley is an amazing offshoot of the Marin Headlands, with hiking trails that suit the whole family. The Tennessee Valley Trail is mostly level; it begins at the parking area and travels 1.7 miles to Tennessee Beach. For the more adventurous hiker, there are a number of other trails leading into the hills above Tennessee Valley.
Dogs, even on leash, are not allowed on any trails in Tennessee Valley except on the Coastal Trail where it crosses the valley, connecting Rodeo Valley and Muir Beach. Dogwalking is allowed on-leash on the Miwok Trail from the Tennessee Valley parking area north to Highway 101, and on leash or under voice control in Oakwood Valley, which is off Tennessee Valley Road a short distance before you reach the Tennessee Valley parking lot.
