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!!!

As you ride out to Mount Vernon, you feel like you are far away from NoVA/DC. Beautiful views across the river. Just be aware of the many roots that are cracking through the trail - not a smooth ride, but a great trail location.

Asphalt appears to be new. Whole trail was smooth and well maintained.

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!

Here's a note I received on 10/5/2021 from the Trail Development Program Manager for the Prince Georges County Department of Parks and Recreation.

Dawn Thomas is the Anne Arundel (AA) County Recreation and Parks point person for the project.

PG Parks is a partner in the project.

The latest news from AA County is that a Pre-Bid meeting was held by the Dept. of Public Works (AAC).

Contractors will be preparing bids for construction in October.

Contractor selection will happen in Nov-Dec. timeframe, and then a contract will need to be signed by the appropriate parties.

Depending on weather and the contractor’s planned schedule for construction activities, work will start in early 2022.

A planned construction schedule won’t be available until early 2022. In general, it will take at least 12 months, however weather will play a huge role in determining the actual timeframe.

My aunt and I took a quick walk on this path. It’s a peaceful walk on a paved path with a burbling creek nearby. A lovely step into nature in the Cleveland Park area.

It was alright - the trail didn’t give much view of the lake itself and also didn’t circumnavigate it. You just kind of end up in a neighborhood. That said it was wide and well maintained and easy to navigate.

I started out planning to ride the entire trail, beginning at the trailhead on Bloombury Rd. I made it to Mile Marker 4, which is another trailhead, and decided I’d had enough for one day. The scenery is absolutely beautiful, but some have mentioned the rocks. At this end of the trail, there is only gravel. My problem, for which there’s no real solution, was the roots that crisscross the trail. They’re not the huge roots that can take you down, but they’re unavoidable, and there are a lot of them, and they make for pretty rough riding. I agree with those who recommend fat tires/mountain bikes.
