This trail has been used in the Fair Hill classic races but for some reason the park does not do a lot of upkeep on the fields that lead to the tunnel. The tunnel is often wet and used by horses mostly. This is the shortest route to cross Gallaher Rd. after a semi truck took out the beloved stone bridge that connected these trails. You may need to ride through tall grass to find it. Look for the dip in the road to find the tunnel.
