We rode this trail on a sunny morning in late June, one of 8 trails we rode that day. Unless you are also trying to ride 150 trails in one year, I don't recommend this trail. Go to the nearby Limerick Community Park and enjoy that trail instead.

Great trail

Great trail until you get close to tinicum. Trail completely closed. Had to go down and up steep embankment to get onto road. It reopens after 100 yards or so. We went up pa side from Stockton and returned on Nj side to avoid it on return. Nj side much wider.

My daughter took me for a bike ride and dinner for my birthday. I had no idea where we were going but it ended up being the Jack Markell Trail and I was blown away that I didn't know anything about this wonderful experience before this. It is amazing. So beautifully built and maintained. It went under and around areas I would never have biked thru. My partner and I are avid bird watcher/photographers and I can't wait for him to get his bike fixed so that we can take a leisurely meander thru with our cameras to see all the varieties of birds. The trail even goes thru the Peterson nature center!! Easy biking or walking. Also saw scooters and skateboards. Highly recommend!!

I really enjoy this trail. The terrain is great for all levels and abilities as the trail is cinder for the most part which is easy on the joints, and the majority of it is relatively flat. If you do the outer most loop there will be two somewhat steep uphills and downhills but if you have concerns just take your time and they will not pose not an issue. The outer most loop comes to almost a 10k (6.2 miles) if you go from end to end. There are several bridges along the way where you can create different loops. Most of the path is well shaded which is fantastic on a hot, sunny day. Today we started at the "Runner's House" and went to Fish Hatchery Road, where we then did a loop around the fish hatchery. We then headed back on the opposite side of the river and looped back at the bridge with the parking lot near the opposite entrance. This gave us about 5.28 miles total.

I enjoy cycling this trail as it is relatively flat and short. I can usually complete the trail in less than an hour. However, parking is not good at all. There is only one place to park on the trail and does not have many access points. I parked a few times at Linvilla but riding down to the trailhead on Knowlton Rd is tight. Cars whip around the corner and there isn't a lot of space on the side of the road to ride.

The good thing about this trail is that it's not crowded. But there's a reason it's not crowded: It just isn't anything that special about it. It's very short, and even in that short stretch, you've got to cross 2 roads with cars coming pretty fast. The unpaved stretch is a nice jaunt through the woods, but just 1 mile, and then you have to turn around. The paved part is about 2 miles, but not very scenic.

Great trail, though its also a very popular jogging trail so you’ll have to be careful. Definitely bring mountain biking tires if you can. The trail is mostly dirt but there are several long patches of loose rock that could prove hazardous to slick tires.

Great ride as long as you know the beginning and end points. I’m from Wilmington and had a bit of trouble figuring out where the trail ended at Battery Park! At the beginning the signs are not the easiest to find! However, the trail itself is in great condition and the scenery is very nice. I’ve run into several animals including deer 3x now. Great for nature lovers.
