The Western Maryland Rail Trail is a paved route that runs parallel to the C&O Canal in Western Maryland. The route begins in Big Pool, MD - in 2019, it was extended from 22 miles to 28 miles, ending in Little Orleans, MD.
Between Mile Markers 24 and 27, the Indigo Tunnel is permanently by-passed by using ramps to the C&O Canal Towpath. The by-pass is two miles long due to a bend in the Potomac River. The surface of the towpath is for the most part an even hard-packed dirt trail.
There are two of these now, one for the older shorter route and this one. I wonder if they should be combined as route-options rather than separate routes.
The 22 mile route used to be the full trail, end to end.
It was extended at the end of 2019, and is now 28 miles for the full route end to end.
