Signs for riders to take caution or maybe even to STOP should be posted at the crosswalk located at Pinecrest Road overpass. Riders are can only see one direction depending on what way they are riding due to sound barriers. On coming traffic from East will only see them when they emerge from sound barriers.

My husband and I took this trail from Hancock, going west, for ~ 16 miles and then back again. We ride multi use bikes.
We thought this trail was great! It has convenient access points and plenty of parking w opportunities to “rest”.
The trail is flat so pedaling is required the entire time but it isn’t a difficult trail. We went in August, so there was plenty of shade from the full foliage.
The trail does have a couple rough spots where roots are pressing up on the pavement but they are not challenging or severe. It has lots of straight stretches, just as the railroad track it follows would’ve had. No surprise there. The bridges that merge the trail to the C & O canal tow path are in excellent condition! There are C &O points of interest to stop and check out and a campsite or two along the part we travelled. Saw a good bit of wildlife but nothing dangerous. While the full foliage blocks views of the Potomac most of the time, the trail is a feast for the other senses. Birdsong is plentiful and the smells of the river and mountain air are easily detected.
I’d recommend this trail to anyone looking for a bit of exercise ( really no coasting unless you’re on an e bike) and I suspect it is absolutely beautiful during the autumn too. No trail we’ve been on is absolutely perfect in every way, but we’ve never had to pay to go on one either, so doubt let the negative reviews of this one fool you.

Started in Cumberland and headed west. Complete glide back to Cumberland

my son and i rode this trail over 3 days camping along the way at West Newton & Confluence. this trail is peaceful and quiet once out of Pittsburgh. The people in all the towns are social and glad to help in anyway needed. The trail has plenty of places to rest and relax. you follow rivers probably 120 of the 150 miles

My wife and I rode this portion of the trail on our recumbent tandem in June. It has been on of our favorites. The climb from Frostburg to the eastern continental divide was not too bad. It was great fun on the way down. ;-). The tunnels and the views are the big highlights. It was so cool how the lights came on as we rode through Borden tunnel. The cicadas were out in force as we rode through the woods. The Mason Dixon line is a great photo stop. We highly recommend the trail and will be back to ride more.

The W&OD is a great bike trail throughout, obviously. But the western part, generally from Herndon to Purcellville, is far nicer and less busy than the eastern part in the northern VA suburbs. The eastern part is my home trail and nice for a quick workout ride, but it is super busy with walkers, talkers, dog on long leashes and obnoxious dudes who think they are in the Tour de France. I like a nice fast ride as much as anyone, but the western portion is not choked with users, much more greenery in a rural-exurban setting, far more beautiful and one that evokes the railroad of yore more, too. Leesburg and Purcellville offer nice rest/eat/drink/chill options if you desire that. Bike from Herndon to Purcellville, the trip back is somewhat more downhill and makes it *slightly* more uphill west and downhill on the return, a nice recipe. It's about 13 miles in that stretch, 26 RT. 4 stars for the eastern bit (after all, a nicely maintained road bike path), 5 stars for western section (as nice as any road bike rail trail, and well paved).

We spent the day biking from Hancock west on the paved trail. Wonderfully maintained. Loved the scenery and although it was warm we had a terrific time.

Last July I walked the north half of this trail (top 20 miles) and today I walked the bottom half (bottom 20 miles). Both halves were beautiful, though I think I’d give a slight edge to the northern half in terms of beauty and general enjoyment. When I walked the northern half last year, I relied solely on the maps provided by fairfax county, which are black and white and not particularly detailed. Since I made it through the hike, they obviously got the job done, but not without a lot of backtracking and hunting for trail markers. The southern half would have been just as bad, if not worse, if I hadn’t found this app last night before I left this morning. For any others considering traversing the entire county by foot-whether in two trips or more-this app will save you from a huge amount of backtracking and stress thinking you have left the trail. Overall, it was a great hike though!

It’s a great trail. Been riding it since the beginning. The elitists need to tone it down though. People like to enjoy the scenery and shouldn’t have to worry about getting ran into or yelled at by the Strava segment obsessors.
