Rode 12 miles today. Started at Bloomsbury Rd., went to milepost 6 (2 miles past Comorn Rd) and turned around. The 4 miles out and back from Comorn Rd seemed more like for mountain biking. Very rough with deep rocks and many exposed roots and RR ties. On the Bloomsbury end there is still rail in place and you must cross the uneven exposed rails once. 2 of the 6 bikers we saw had accidents crossing the rails.
Easy walk on an asphalt trail. Almost all in trees. 1.4 miles or so up, 1.4 miles back. Easy parking at both ends.
The view from the dam, with the lake and fall colors is magnificent.
I recently walked virtually every foot of the 40+ mile long Jerry Connolly Cross County trail, in both directions. This includes the part of the route which is not a trail at all, but a 2-mile long sidewalk along a busy road. I would start by driving to a starting point and walk about 5000 steps in one direction, stopping at a convenient point where I could park my truck nearby. Then, I walked back along the same trail. Most of the southern part of the trail, from the Occoquan river to Arlington Blvd is paved in asphalt. Almost all of the northern part, from the Oakmont rec center to Great Falls park is a rough trail. This part would be quite muddy after a rain. Most of the trail parallels a stream, from Difficult Run in the north, to Accotink Creek in the middle, to Pohick Creek in the south. Trail markers range from excellent in some parts to hardly noticeable in other parts. Having Google Maps on a phone app was super helpful at times when I accidently veered from the trail, or was at a point with a fork in the trail. There are several signs along the way with a map of the trail in the near vicinity. These were necessary and helpful when the trail came to an apparent end and the resumption point was several yards away. Almost all of the trail is an easy walk with just a few steep-ish ascents and descents. Most of the trail is really quite pretty. Overall, a very fulfilling experience for me.
Great trail. Not too crowded. Lots of shade. We biked the loop with our six-year-old who rides a fixed gear bike. A few hills on the south side were a bit steep, so we did some walking, but the north side was much easier. Definitely going back.
The main trail incorporates a mix of asphalt and gravel surfaces with great views. There’s also a number of off-trails that offer more of a trail running experience through the deeper woods. Love this place!
Very calming trail with little to no traffic at 7pm.
The map gave us the start of the trail. But, it was in a neighborhood and there was no parking at all.
As others have said - this trail is very bumpy. Much of the trail still has railroad ties going across it. I did on a touring bike and even deflated the tires partway into the trail. I still called it after 8 miles. Just not much fun. Hope they will improve it a bit sometime because I lived the countryside and overhanging tree branches etc. Really beautiful. Good walking trail or mountain bikes.
