The Paw Paw Tunnel is only open for visitation, but NOT for riding through. I was riding the C&O both ways in mid September, and the tunnel was closed, and cyclists were walking their bikes over the detour route.
There are signs there, on both sides, indicating that you can walk and visit the tunnel, but you cannot ride through it.
