North of Cobourg, the 5300 acre Northumberland Forest has an off-highway vehicle trail system for use by dirt bikes.
To reach the Northumberland County Forest dirt biking trailhead from Route 401, follow Route 45 for 14 km northeast to Beagle Club Road. Proceed north on Beagle Club Road for 1 km to parking area on left.
Motorized use is preferable east of County Road 45, you can park at Dunbar or Morris Roads on the east side of County Road 45 (west of 45 is heavily used by hikers, horseback riders etc, they can be unexpected on the trail, we currently direct motorized users to the east to avoid conflicts). Please respect the forest environment by staying out of wet areas and off steep slopes.
As of May 2008, the Northumberland County Forest is developing a forest management plan. Therefore, there are currently no fees or permits required to ride in this forest. However, there are trail patrols enforcing that 1) riders are licensed, 2) vehicles are insured, and 3) that riders have helmets.
Overall, Northumberland County Forest is the 3rd most popular dirt bike trail of all 15 dirt biking rides in Ontario.
