Had a nice time yesterday (9/28/20) on the stretch from Morris west toward Seneca. Note however that the part just west of downtown Morris that goes over Nettle Creek is closed in both directions; you can't proceed west if you start in downtown Morris and need to detour on city streets for awhile.

If you're starting from Morris and want to go west, a better bet is to park at Gebhard State Woods (but note that you cannot head east from there, just west).

In our pandemic times, I stay off the overused trails in & close to Chicago.
Because of limited access points, this trail fits the bill as sparsely used.
Closer to Rockdale, the trail is a bit overgrown, and there are a few spots with loose gravel. I wanted to ride to Gebhard Woods, but did not find the trail. (People in Morris want you to see their downtown.) But that was fine - I did ride around Morris before I returned to Rockdale. This was the flattest ride I have ever done!

Overall, this was a great trip. It's a towpath so as you expect, almost no change in elevation. Most of the trail is hardpacked gravel, with some pavement. I wouldn't recommend any portion of the trail after much rain, the trail would be too muddy (particularly between Utica and Ottawa). We were really impressed with the staff who seemed to be keeping the trail working. On Utica to LaSalle, there was a downed limb blocking the trail, but it was gone by the time we returned an hour later. Everywhere else, the trail was mostly free of litter except in some of the towns.

The western third from LaSalle to Ottawa is very scenic, with a few of canal, river, caves, flora, fauna, and sandstone cliffs. Someone created a small bridge at the washout between Utica and Ottawa. The middle third from Ottawa to Morris is not as nice, although the stops in Marseilles, Seneca, and Morris are nice. The trail in Seneca stops right next to a well kept Casey's with a clean bathroom, friendly staff, cold gatorade, and a free air compressor. Most of this segment the canal is gone and the trail is down to a small single file track, but still heavily wooded at least. Morris itself is really scenic, but you have to detour around another washed out bridge, I think the route was Ottawa to Fremont/Jefferson to Nettle. Morris to Channahon was our favorite segment, particularly around McKinley Woods and Channahon State Park. The woods and river views were beautiful and the canal waterway was in the best shape here. The section from I-55 to Rockdale was again not-so-nice, reasonably well wooded, but few amenities and not the greatest scenery.

There are few places to stop close to the trail east of Morris. Near Channahon State Park where the trail crosses US Route 6, there's a subway and gas station nearby.

The part through the downtown of Lemont is very nice but going west is in bad shape and east bound is gravel, not well maintained. In parts, if you had an accident they might find you for a few days. Short trail in both directions - goes no where. Skip this trail and ride the Cenntenial Trail on the other side of the river. It is a 5 star trail - Lemont is a 1 star

If you are in the Chicago area, and you love biking then this must be in your explore list. Breathtaking Scenic Route!!

We rode the Channahon to Morris section after the storms in early August. There were a couple of trees down but overall the path was clear and very scenic. Lots of birds, lots of shade and mostly flat. It is mostly limestone and can be slippery at times for touring bikes. There is a toilet at Channahon, it is a latrine (no flush toilet) and no place to wash your hands. We had planned to stop in Morris but didn't see the connection to the next part.

Contrast that to the Ottawa towards LaSalle portion that a few days later had major trees down every 1/2 mile or so, some of them really big and hard to get over or under. Surely this is temporary but may be an issue for a few weeks to come as there were a lot. We decided to ride on the street on the way back to Ottawa (we only went 6 miles because of a branch that lodged between my brake and wheel and flipped me off my bike) once we got to Buffalo Rock State Park. What little we saw of the trail wasn't as scenic as the Channahon to Morris section

I'm pretty new to the area and haven't read all the other reviews here, but have enjoyed riding portions of this trail and will finish the whole thing soon. If you ride at night it gets dark because most of it is unlit wooded areas and there are few street lights. Only complaint is that as of Summer 2020, there are quite a lot of tree roots buckling the asphalt and even broken through in some spots. I have a road bike and any cycling enthusiasts know how harsh it can be to hit those anywhere above 15 mph without big tires or a suspension. There are also some bridges with uneven planking that will make you feel like you're dual-wielding two machine guns as you cross. A great trail overall but road bikes are in for a mild thrashing.

There is limited parking at the south end of the trail, as they have torn out the park to build condos. There is more parking, with a porta potty, a little ways north on IL Rt 25. Otherwise, the trail is superb in the south section. I have ridden every section south of Algonquin, and except for small portions where the pavement needs some work, and the bothersome on-road sections, this is a wonderful trail to ride.

The route is very scenic but the quality of the trail isn’t great. At the start in Aurora, there are too many street crossings. That goes away in about 2-3 miles but the asphalt hasn’t been kept maintained so lots of cracks. Recommend for hybrid not great for serious road biking.
