This trail seems to have been designed by a highway engineer with not enough consultation with bikers or landscape architects or conservationists. Its essentially a bike highway, graded, paved and fenced just like the highway it runs right along. The land around the trail is aggressively mowed so there is no vegetation to support wildlife or provide shade for trail users. Very noisy from highway traffic which at times is only a few a few feet away. We won't be back.

We picked the rail trail as our first venture back into biking after 5-6 years away. We started in Hancock and went west. The scenery was STUNNING and the ride was easy for us unseasoned riders.

From riding along a corn field with a backdrop of rolling hills in dazzling fall colors, to passing a cow field dotted with burnt out houses, to heading along a sheer drop off and between a narrow cut out in the rock, this route was absolutely stunning. I can't wait to head back and tackle another stretch (Or even the same one again!)

I took my bike and started up this trail from its terminus at the Occoquan Marine Park near Lorton, VA. For the 1st mile, it was obvious, a nice paved trail heading inland slightly up hill. After a mile, I encountered a cross-walk. There was NO marker on the other side, but I assumed the trail continued there. It then went into and around the side of the old Lorton Prison, which is now called the Workhouse complex. Within the complex, the trail ... just came to a stop at a parking lot. No signs, no arrows ... no anything. The map which Traillink provides showed no clear detail of where to go next. I asked 3 people, none of whom had any idea. I biked around all the buildings, went out onto the street, found nothing, and got ready to quit. Then, I talked to a biker who said to find the trail, I had to go out onto a main road (Workhouse Rd.), turn right, and I'd eventually find some signs. I biked over a mile, went into another park and biked around, and found nothing. Finally, I saw what looked like the trail, going UNDER the main road through a tunnel. Biked back up Workhouse Rd, eventually found a small branch off the road with a small GT trail sign in the back, followed its paved trail, only to find it dead-ending. Backtracked and discovered I had to branch off the paving onto a dirt trail to keep on the GT trail. Took it for 1/2 mile, came to a fork in the trail, but again, no sign as to which fork to take. I then gave up in disgust, and biked back to my car.

This trail markers are very poor. Fairfax Cty is a major well-maintained municipality. One would think its major cross-county trail would be reasonably marked. Its not. Thoroughly disgusted!!!

Most of the recent reviews are spot on. If you are used to crushed limestone or asphalt the bulk of this trail is bumpy and full of exposed rocks, ruts and tree roots. The downside is you have to keep your eyes front and center most of the time. The Paw Paw Tunnel detour is a real challenge. I only had two panniers that were not full and it was a struggle. Can’t imagine how the fully loaded bike packers did it. (But I’ve also not done any mtb, so that could affect how easy/hard it was.) But the amount of history and really cool places to stop and explore make it worth it. Beautiful aqueducts and lock houses as w.landmarks makes up fo me the trail conditions.

***ATTENTION***
The Paw Paw detour due to the tunnel being closed which with talking to the construction crew, will remain closed for another 18 months (Spring ’23) but when reopened, it will have a new riding surface.

The marked detour is not like any other that I have ever experienced on a trail which normally is a divert to local roads until you can rejoin the trail. Eastbound is best described as a mountain bike trail which is narrow in sections and at a 10 to 15 percent grade with exposed roots, rock gardens (rocks vertically embedded in the trail surface) and other obstacles. With a bike loaded down with gear, it is extremely strenuous to make it to the top and over the tunnel. Just pushing your bike up and over East bound is a challenge also.

Westbound is a trail that is a large enough for a vehicle but also has 10 to 15 percent grades but has a loose surface for a majority of it.

From Cumberland to Paw Paw, the trail is need of maintenance as there is numerous hazards to include mud holes that are deep (10” to 12”), segments of large branches and this time of the year with leaves falling, they hide some of the obstacles. You must keep your eyes on the trail and not sightsee for this section of C&O.

Also, confirm your dining options along the trail as even if sites on the internet say they will be open during your visit, you may be disappointed and going hungry due to the lack of staffing.

The rest of the trail is in great condition to DC and be aware as you approach the Capitol and it is on a weekend that there will be plenty of trail traffic as they enjoy this gem in their backyard!

Seems like a great path but horribly marked. I started at the Occoquan end and made it maybe five miles before getting frustrated and lost several times. There are intersecting trails, neighborhood paths, etc. that all look the same but no signage to tell you which way to go. Halfway through I started using this app for the trail map and still got off the trail several times.

I completed this ride the first week of September, cycling from Cumberland to DC the day after Hurricane Ida passed through. The first time I have done a multi-day ride. Took the Amtrak to Cumberland with my bike and stayed at 9 Decatur (recommended). The trail was in good shape. A couple of additional puddles from the rain but very rideable. I had a great time. Four days and three nights. Rode 50/50/50 and 30 miles. Camping worked out very well at the hiker/biker sites. The only major hitch was the Pawpaw tunnel had just closed and taking a bike loaded with gear up and over is quite a slog. Hopefully some entrepreneurial locals have come up with some drive around alternatives. Unless you are a purist I recommend taking advantage if they have.
Don't expect stunning vistas but settle in to a rhythm and enjoy the history and it is a meditative and fulfilling experience.
Thanks to all the park staff who keep the park in such great shape.

This is a nice scenic shady trail, however it’s pretty overgrown in certain areas.

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.
