Allegheny National Forest is opening up additional trails for off-road vehicles.
According to the U.S. Forest Service, the Rocky Gap and Marienville trails will be open starting Friday.
Permits are required to ride on the ATV trails.
Forest Service officials say winter trail conditions are more challenging, so riders should know what their skill level is before using any of the trails.
The trails will stay open for as long as the conditions support winter use.
