I really want to give this 5 stars because it is a gem of trail for the community and surrounding area. We had a camper van so parked off of 10/39 and S. 250 W just outside of North Judson. Trail was paved, but there were some dips to be mindful of in one section closer to North Judson (mentioned by someone else) otherwise it was well maintained. Heard lots of different species of wildlife and enjoyed our ride. Would we make this trail a destination? No. Would we change our route 20-30 minutes to be able to ride this again? Yes.

Rode the OPRT for the second time yesterday (4/25), covering 31 miles from Western to Cedar and back.

Most importantly, it's a great ride through the far south suburbs - easy to access at several points and with Frankfort more or less midway-ish if you want a break to eat or drink. Also, the trail is almost completely straight and flat, not counting a few moderate climbs for overpasses and some stretches of *very* gradual incline or decline. A few areas with root-bumps in the trail, I've seen better and worse in this regard.

This may be unique to our chosen days of riding, but we have found the OPRT to be a very windy trail. There is a fair amount of tree and brush cover, but also large open areas (including one area where you traverse a large pond on a narrow causeway). Our first ride was last November, this time mid-spring. So, granted, spring and fall can be turbulent weather seasons. But both times the trail was so windy, we decided it would be a great place to return on one of those 90-degree summer days! Your mileage may vary on this issue.

Also, strangely, we encountered FOUR motor vehicles on the trail yesterday - three cars and one trail bike. All were east of Frankfort, and the three cars were near Western where we parked. One parked, one idling, and one moving - ahead & away from us. Haven't seen anything like this on other trails, other than an occasional vehicle doing trail maintenance; this was not that. The trail is clearly posted, no motor vehicles, so these folks were just flouting the rules. Again, don't know if this is common on OPRT but we didn't see it the first time. At one point we were BETWEEN the parked and idling cars, which felt a little hinky. But no issues, we weren't accosted, etc. Just a few individuals using a resource for its other-than-intended purpose.

Good workout due to the many hills, maybe not for beginners but not too advanced either. A lot of people walking but fairly wide trail. I went counterclockwise from the Lemont parking lot so it’s more downhill at the beginning and more uphill towards the end.

I rode the north end of this trail three years ago. It was very enjoyable and I would give that ride 5 stars. Ever since, I've looked forward to riding the south section.

I made the trip on Easter Sunday. I started at the trailhead at the NE corner of Midewin off Hoff Road. From there, I rode south, a 25 mile out-and-back to Custer Park. Pros: beautiful weather, interesting little towns, wide open vistas, light traffic, friendly folks, Kankakee River bridge. Con: the trail remembers everything that traversed it when it was wet and soft. There were petrified bike tire ruts, snowmobile/washboard tracks, deer hoofprints, bootprints, etc. In addition, as others as mentioned, there are a few soft spots, but worst of all, a verrry rocky section along Midewin. The ride was a boneshaker and I spent way too much time looking at the trail instead of the scenery. The south section could be a 5-star section, too, but based on the rough surface, I give it 3 stars.

Will County FPD says they're making improvements: https://www.reconnectwithnature.org/News-Events/News/Limestone-Screening-Work-Begins-on-Two-Mile-Sectio . Hopefully future riders have smoother experiences!

wonderful trip across America

This was an excellent choice for the first longer ride of the year. I did an out and back from the south end. The trail was not crowded, but there were enough people passing by to feel comfortable. The trail is in good condition as evidenced by the significant number of road bikers zipping along. The only sketchy location was at the curve just southeast of the Lemont Road crossing. The trail there was muddy and people were riding on Canal Bank Road, but beware of the big pothole going westbound. It was semi-hidden in a shadow and hitting it would be bad. The ride was serene, with an interesting mix of open water and industrial views. I took the hike up Centennial Hill and agree it's worth the time.

Prairie Duneland was the first rail trail we rode, so for us it's a sentimental favorite. It's also close to home, so we ride it often.

As others have noted, most of the trail is well shaded and screened by trees, making it a cooler ride on hot days. The tree screening also helps make windy days more manageable.

But, with trees come roots, which often are the source of bumps and cracks on paved trails. Other than a short stretch near the Cleveland Avenue trailhead in Hobart, this trail mostly has escaped that problem. (Technically, that stretch is actually on the Oak Savannah trail, see below.)

Another good thing about Prairie Duneland is that it connects to several other trails. Just west of 149, the Iron Horse Heritage Trail branches off to the north - at about 2 miles it's a relatively short but nice trail.

Prairie Duneland also connects seamlessly at its west end to the Oak Savannah trail - in fact, if you start in Chesterton and head west, the last mile and a half or so before Cleveland Ave is actually the Oak Savannah. If you're so inclined (and willing to put up with a stretch of some twists and turns with non-existent signage through downtown Hobart), you can ride the entire Oak Savannah, link to the Erie Lackawanna Trail in Griffith, and end up in Crown Point.

These trails are all almost entirely flat and well paved. The one warning is that a rail crossing at roughly mid-point on Oak Savannah can sometimes be blocked by stopped trains.

I agree with the reviews of the trail south of Lake Cook Rd. It’s ok for a few miles south but there’s a notable difference of trail conditions from the trail north. Two different counties and budgets to maintain them, I assume. Traveled this trail multiple times this past COVID season. It’s my first year biking in 40 yrs and wow, what a great trail.

Runs along the river. The park is nice but the trail seems a little dirty with trash around the sides. There are multiple benches along the trail for resting. Not a bad trail, but not a very pretty trail either. So if you’re looking for some sight-seeing as you run then this may not be the ideal spot to run.
