We started at the Visitor Center, (very close to Interstate 80); headed west till we came to the feeder basin and headed north for 4 miles, turned around (due to poor conditions) and went back to the feeder basin to continue west for another 4 miles, then headed back to the visitor center. Total round trip around 27 miles.
We are not from the area and were looking to break up a long car drive, this seemed like the perfect location. I must say the scenery is beautiful, we saw many wild animals, biked thru a patch of grasshoppers (hundreds of them), saw beautiful herons, a long nosed fish and a flock of wild turkeys - stunning!
But as for the path, well I could not tell any paved stretches. Most was light soft gravel or overgrown tire tracks, but the worst part was how overgrown the side brush was, covering 1/2 to 3/4 of the path, especially in the northern section. I was hit by so many branches (we were there in late August, it didn't look like any mowing or trimming had been done all summer). Between that and having to watch for obstructions in the path, it was not very enjoyable. To me the path was very "bumpy" and trying even a pace of 10 - 12 miles an hour was tough.
If you're out for a leisurely stroll, this may be a good path, but the section we rode needs maintenance. And it was very disappointing when we arrived at the Visitor Center on a Monday afternoon, for it to be all closed up, no maps, no bathrooms. The one bathroom we stopped at on the northern section was a mess.
This path has potential, it's a shame it seemed to me no one maintains it.

I rode the entire length ( except for The Stone bridge Trail Portion at the end). I agree with other riders that the asphalt is bumpy and repairs are needed in some sections. However, the trail is flat, tree covered and pretty much an easy ride. The trail head in Capron ( at least I think that’s Capron) has parking, facilities, and a picnic table which was nice. I would recommend everyone to ride this trailleast once

09/01/2021 - Excellent trail. Beautiful September day for a ride. This is a well maintained trail perfect for road or mountain bikes. Rode from Sycamore trail head to the St. Charles ( LeRoy Oakes Forest Preserve) head and back. I can highly recommend to any biker looking for a great ride. And a special thanks to the gentleman who joined me spontaneously for part of the way. Good conversation always makes the miles go fast.

This path is well maintained and it is mostly shaded making it easier for sunny days.

Just hit the trail today from Tutty's Crossing in Freeport all the way to Wisconsin state line (35 miles round trip). It's been 3 years this month since my last ride there. It's in great shape and the weather was perfect. Great scenery for small towns and farmland. Plenty of food, drink and shopping in Freeport. (Definitely check out Union Dairy at Douglas and Adams!)

5 star trail for any serious biker.

Hi everyone-- did the trail July 31, 2021 on a Diamondback Insight Hybrid, 75 degrees and partly cloudy day.

The trail is...not bad. I wanted to give it 3 1/2 stars, so will round up here. I crossed the state --largely using I&M Canal + Hennepin along the way-- starting at Co. road 1200 E (NW of Wyanet) going all the way to Colona, near the Quad Cities. Generally, the further west you go the better in terms of trail surface. Where I started on the eastern portion it was like riding on 'crushed peat' -- grassy and narrow. The asphalt-ish surface starts around I-80 and goes northwesterly from there. There are a few spots that are 'large' gravel but I wouldn't get too worried about that.

I wish the Hennepin was more marked (mile markers, etc) like the I&M Canal. Not much you can do about the lack of services, so bring plenty of water, snacks and a fully-charged cell phone. Princeton and Geneseo are great bookend towns, so to speak, although Princeton is a bit north of the trail. Very peaceful ride, although a little monotonous after a while. The feeder basin area (where the Rock Falls spur branches off) is pleasant.

A hybrid or mountain bike is 'probably' the best way to go here...especially on a dry surface...which I had, thankfully.

Dreaming a bit here...but I think a fully-paved trail between the Quad Cities to the Indiana border, largely using the Hennpin, I&M Canal and Old Plank Road Trails would be amazing and a financial boon to towns along the way. But the cost of constructing such a thing.............

This is a lovely trail! Fairly level with a few inclines along the wAy, this trail is well maintained and it’s such an enjoyable ride. A new fire house in Lily Lake has a bike pump and a water filling station. A large picnic table is available for a nice stop. Restaurants are available along the trail but you have to cross Rt 64. The Dean Street parking lot is nice and has restrooms. My friend and I love the Fox River Trail, but we’ve just made this trail a new addition to our favorite list.

After riding Joliet to Morris the week before I was anxious to do the section from Morris to Marseilles with the expectation to go to LaSalle. This was a mistake.

The trail coming out of Gebhard State Park is okay for a few miles, then it deteriorates quickly. Long sections are single track with grass and weeds tall enough to catch you mid-shin. Once you get to Seneca the trail turns into a farmer's access/driveway, with large sharp gravel on hard dirt, so easy for punctures and rough to ride on. This carries on for a good mile or so, then turns into mostly grass until you reach Milton Rd. From there the trail dog-legs across the [dry] canal and is even worse. The only parts that are good are where the rail lines cross the trail. Here they have completely redone the grading and the crossing, but only for a few yards on either side. It's easier to just ride the street (Broadway) on the south side of the path. If it were allowed it'd be much better suited as an ATV trail.

Continuing west into Marseilles doesn't improve. Looking at the trail going west of Main street doesn't look any better. From that point I abandoned my ride and took country roads with additional miles all the way back to Morris just to avoid the harshness of the trail.

Two weeks ago rode the section from Hollywood Rd (Joliet) to Morris. Overall not bad, but there are a few sections where narrow tire bikes might have some issues. The bridge over the river in Channahon was out, so you have to cut through Channahon State Park and cross using the road at Bridge St.

The next issue is on the west side of Morris where the trail (both sides of the canal) are supposed to cross Nettle Creek. On the south trail the bridge is out, and trail is closed. The north trail is basically non-existent and also no bridge. You have to backtrack a few blocks towards town then ride north to Jefferson St. From there go west as it changes to Fremont St. Turn left at Ottawa Street to head south and enter Gebhard Woods State Park. As the parking area starts there are stairs to the right. You can climb these to catch the trail heading west, or continue through the parking lot past the latrines to where the path goes up an incline to also catch the trail.

Overall it wasn't too bad. Some areas the path really thinned out, almost to a single-file path.

Something I noticed. There are almost no places along the trail to refill water. There are fountains at Channahon State Park and Gebhard Woods State Park, but both were out of order and covered.
