Western Maryland Rail Trail (WMRT), MD
To get to the trail head of the Western Maryland Rail Trail (WMRT) from Arlington takes about 1.5 hours. Go North on I270 which becomes I70. Get off at Exit 12. At the end of the ramp turn left on 56 (Big Pool Rd). Within half a mile you will see the WMRT parking lot on the right. The path is paved and wide. Excellent tree cover so you can bike there on the hottest of days. The path goes parallel to the C&O canal and is about 100 feet above it. You get some lovely views of the hills. Overall its a pleasant bike ride. Nothing extraordinary, flat all along. I enjoyed it.
