Trail was a bit confusing. Saw multiple bikers even though it says no bicycles. Best part would be not too much foot traffic and enjoyed the water ways.

The section on the C&O canal was beautiful and full of wildlife! However, the linkups were incredibly confusing, and the trails were not very well maintained. At the west end of the canal, you have to walk down Violette's Lock Road, down a side road towards residential houses, and pick up an unmarked trail that weaves in and out of park land (sketchy).

Easy hike. Not much of a view of the river if you just walk down the clear cut.

But a decent view of the Potomac from the rocks. If you take the trail to the right that is about halfway down the clear cut. Little bridge to cross to get to it.

Blended the woodsy trails with the C&O on a balmy December day. It was absolutely beautiful and a great mix of easy walking and short climbs. We brought our 60lb shepherd mix and she had a blast. There are several trails in this part of the woods; I'd do this loop again and trade out some of the trails back to the car for a different view. We probably had a better view of the river since the leaves were off the trees but I'm sure it would still be pretty in spring/summer.

Walked from C&O Canal (Riley's lock) to Berryville Rd.
The C&O parking area and Seneca creek mouth are crowded! But plenty of parking; and a functional water fountain right at the canal.
The trail portion from C&O canal to River Road isn't clearly marked - going North along canal, cross the creek, and suddenly a footpath appears on your right that crosses the Canal. Follow it a bit, and and old mill ruin greets you, along with a 0milepost for the Greenway.
The Greenway then follows a gravel country road along Seneca Creek; which is not really a hike in my book; hence only 4 stars. Once crossing River Road, the trail is on the hardtop River Road to cross the creek, then an immediate Left onto Old Seneca Road--not really pleasant as you're on asphalt for another quarter mile or so. There are blue poles that evidently serve as blazes along the shoulder til the trailhead on the left takes the path back into the woods. Big sign, can't miss it - also room for a car or two to park on the shoulder opposite the trailhead.
The 1.3 miles to Berryville road are terrific --easy, fast hiking, a few bridges and lots of seclusion.
Enjoyed it and will go back to do the rest of the lower portion up to Rt 28, and then finish the middle and upper portions including the Magruder Trail connections.

Walked this today from Black Rock Mill Road to The Potomac River. Well marked and easy to follow, though a bit weedy in places. Saw only two other people on the entire stretch even on this holiday weekend. More surprisingly, saw no canoes or kayaks until I got within a 1/2 mile of the mouth of Seneca Creek at Seneca Landing. Saw a couple deer, squirrels, and a chipmunk. The chorus of singing birds all along this trail are a treat. Have now walked The Seneca Greenway Trail in two sections on two consecutive days from Rt. 355. Considering this trail's proximity to the DC metro area, it's surprisingly rural, woodsy, and, amazingly, very few road crossings. If you're looking for a trail to find some solitude without making a long drive to get there, this trail is a good choice.

It's an overall enjoyable series of trails. Well marked--just not anything special of note. It's a decent workout for a trail-run. Just don't expect to be wowed by anything.

The scenery on this hike was pretty. It's dog-friendly and has a creek that crosses the path. That being said, the trails were really confusing to follow. It intersects a busy road twice and was not well marked.

Confusing trails.

All Trails app has no data but a Track shows up. - Follow it, it's the best route.

Trail maps here:

I mostly followed the Track above. I recommend following it - it's the best route if you want to avoid annoying River rd noise.

Blockhouse Point Park trails are well marked and have blue blazes. Western sections of the Track fall outside the park trail system.

Start: Pennyfield lock parking lot. Walk back north on Pennyfield Lock rd - look out for mowed path on left a short way up.

Pennyfield to River Rd Parking: Busy trail, well marked.

River rd to Callithea Trail: follow Track south on the pipeline gap to Upland Woods Trail and connect to Blockhouse Trail on any of the connectors (Fawn, Turkey Fan, Spring House).

DO take Blockhouse Trail to end, viewpoint for lovely views (not on the track). Double back to pick up Callithea trail.
DO take Paw Paw trail to end, viewpoint for gorgeous views. Double back to Callithea trail.
CAUTION: Cliffs on both of the viewpoints above. Exercise care with dogs and children.

TRAIL UNMARKED at the end of Callithea - follow well defined path on track to an obvious split in the path at a pretty glade (with old corrugated pipe). I made a left here. Path follows edge of C&O park territory to Violette's Lock rd.

Turn south on Violettes and east on towpath. This is a super pretty stretch. You can get down to the river with a little bit of scrambling to enjoy the rocks if the river is low ( be careful!).

Great place for a variety of activities. As in the other review I didn't see any canoeing. Lots of beautiful scenery and places to stroll. Dog friendly, a definite plus. For those interested in group sports or working out, there are lots of options. Signs could be a little more detailed and visible as it is a little difficult to find the routes you're looking for on the first visit. Well manicured and not too infested with bugs flying around.
