Fort Rock is the commonly known name for two separate Town Forests, the Henderson-Swasey Town Forest in Exeter and the Oaklands Town Forest in Newfields. They are separated by Route 101. Joining them together is a large metal culvert that runs under the highway. This area is known for some of the best mountain biking in the NH Seacoast area.
Stratham Hill Park in Stratham is another great resource for mountain biking. The park is open from dawn to 9pm. One of the best views of Great Bay can be seen from the Fire Tower at the top of Stratham Hill.
