This was my first ride on the C & O in years. I've stayed away due to rough gravel, pot holes, and rocks that even my hybrid couldn't overcome. But recently I heard that there had been resurfacing at Shepherdstown. What a world of difference! Crushed limestone that is compacted into a very level trail. We rode north from Dargan Bend to a couple miles past Shepherdstown. Dargan Bend was the closest parking lot we could find across from Harper's Ferry. Being there in late fall, the trees were bare but the river views were great. The trail north of Shepherdstown is gravel with rocks protruding here and there, making for a rough ride. We only traveled until hitting 10 miles from our start before turning back. Our timing couldn't have been worse as there was some kind of a foot race going on, but since we traveled 100 miles to get here we rode anyway. (I checked the NPS.gov website before going but saw no mention of the race, so not sure how one finds out about events on the towpath.) Overall, though, it was a great 20 mile ride.

The trail is really smooth and well-maintained. The bathrooms and water stops are in great shape. It’s a great place for an out and back on the bicycle or a pleasant walk for any segment.

Ride side-by-side the whole way. Good hard surface for mountain bikes, just a very few soft sandy spots along fields. Pretty flat (a degree or two) except for a few road crossings.

Can start downtown Shippensburg, or we usually start a mile East at the Shippensburg Township Park to avoid walker congestion. Wide path with no power lines, can ride side-by-side the whole way. Very scenic on the bike, when there are banks on the side they can be typically seen over if on a bike. Quite a bit of tree tunneling to pedal through. There is also quite a bit of unprotected trail, so would not recommend riding on hot summer day with sun directly overhead. Especially true past Newville.

Have done this trail a dozen times over 5 years, it is consistently good with light traffic once you get away from the University. Good old/Amish/Mennonite farm scenery with animals, there is a one mile section with views of the mountain range 10 miles away. Stunning. This is one of the prettier trails we've done in the last 10 year.

Facilities along way. A great old ice cream shop with a non-working soda fountain in Newville. Be sure to go inside, though they also have picnic tables outside.

Recommend early spring through late fall, avoid hot summer when the corn is tallest and the sun directly overhead. Benches and sufficient picnic tables along the way, though nearly all are in direct sun in summer.

I'd say this is mostly a way to conveniently get around town. Say if you're a Rockville resident and worker, it's probably pretty good for commuting. The scenery isn't that great, and it's quite loud for a lot of it. However, it's fine for getting exercise around the area.

On 10/22/20 my friend and I rode the above stretch. It was absolutely beautiful! We were cautious due to the mornings heavy fog and all the damp leaves on the ground. Made the paths edges somewhat difficult to see. The trail was extremely smooth until you get to the Brunswick Waste Treatment Plant, where you share the dusty and bumpy road with big trucks coming and going from the plant. Pot holes were terrible there. But once back on the trail, it was a smooth sail. I believe it was around a 28-mile ride for us.

Very scenic route, paved bike path. We went on a Sunday after 2pm and it wasn’t crazy packed. It is true that there are a bunch of hills so be prepared for a workout. Definitely worth a try.

We did about twelve miles of the western part. Really pretty. We will be back!

This is a well maintained trail, with smooth asphalt throughout. Good for late fall and winter months with great sun exposure. It lacks sufficient signage. The most confusing segment is crossing George Avenue going east to west. There is no directional signage indicating where to cross Georgia Avenue at Emory Lane. Once on the west side of GA Ave, nothing distinguishing the GA Ave trail from the ICC trail.

Did the entire length of the Carl Henn Millennium Trail, starting at Grandin Ave going clockwise. Quite a few stops/intersections in the section near MD 355 but became fewer. Trail is for the most part wide and smooth and well marked with signs and arrows as well as with mile markers on the pavement. Some sections also have a center dividing line, others do not. The section on East Gude Drive is through an industrial area, and is narrower and the least pleasant with heavy traffic, but seemed relatively safe. Portions of the trail appear to be paved over sidewalks that are right next to vehicle traffic, with no buffer or green space in between whatsoever. Few drinking fountain or restroom facilities. However, overall it exceeded what I was expecting for an urban trail, and was a relatively pleasant, safe ride and good workout.
