This trail is the beat I’ve ridden on. I’m new to biking but this trail, so far, is my favorite. Paved the entire way or off roading choice if you’d like as well. I like to mix it up a bit.

We rode this trail in early Nov 2020, and liked it so much we returned two weeks later for another run. This is one of the most interesting of the suburban trails we have ridden, with a number of bridge crossings of the creek. The trail winds through various Forest Preserve forests and meadows on its north end, before veering due south at Glenwood for a long straight stretch, then wanders through several pleasant neighborhood-adjacent parks before ending at Sauk Lake.

Well worth adding the very peaceful and scenic Black Trail loop around Sauk Lake, just be prepared for that one steep hill at the back, lol! An added benefit is that Thorn Creek Trail is amazingly smooth, with very few of those root-bump cracks that you always seem to feel so much more on the return trip.

Ignore the nonsense in the "Parking and Trail Access" section about the northern trailhead being at "Wapum" (Actually Wampum) Lake Woods. There's no trailhead there, they need to change that. Park at Lansing Woods on 186th just east of Torrence.

I am thrilled to share that the worst part of this trail mentioned in several reviews here has been freshly repaved as of November 2020 (from Route 30 all the way north to Colfax Street). Previously, this section was marred by huge cracks that ran across the full width of the trail every 20 yards or so. These cracks were between 1 and 2 inches wide – enough for foliage to blossom within – and were absolutely jarring to hit on a road bike. Now, this section is buttery smooth and an absolute pleasure to ride on.

This now places the worst section of this trail in Hammond north of Interstate 80/94. With the exception of the new pedestrian flyovers that cross Columbia and Calumet Avenues, the rest of Hammond's share is quite rough. Still, I enjoy completing the entirety of the trail from Downtown Hammond to Crown Point and back. When I start off in Hammond, I typically park in the visitor's lot of the Hammond Police Department off Douglas St. for some extra peace of mind with respect to my vehicle being left unattended for hours (downtown Hammond doesn't have the rosiest of reputations).

I parked just north of Golf at 294 right over the train tracks. Took the trail north and I loved it. The tracks do separate the trail and I’m surprised it’s not connected. The people who make and maintain these trails are national heroes. The dirt road north is perfect for mountain bikes. I rode about 7 miles to highway 68 I think it is. Awesome.

Agree with all the posters below: this is a great trail and another example of what gems these FPD trails are! So close to urban, highway, and residential, yet a secluded ride in the woods.

If riding south and west, park at the Red trailhead at Lansing Woods, just east of Torrance on 183rd Street. Late season and winter, mind the wind direction before choosing which way to ride this trail, as much of it runs due south.

11.8 miles to the end of the red trail, then you can tack on 4 miles on the black loop. 11.0 miles to the east end of the Old Plank Road trail.

This well maintained trail connects the Rock Run Greenway Trail to the I & M Canal Trail. The trail passes through a quiet suburban area on the north and through a more wooded and somewhat industrial area on the south.

Particularly to the north the wide trail accommodates side by side riding easily.

Overall a nice addition to the two above mentioned trails albeit too many busy streets to cross for 5 stars.

Best work out I had in a long time, I have been going for a moth + I love the u hills and the terrain is perfect.

This is a great trail for kids. My son and I went rollerblading. The trail is flat, so no big hills to manage. We had an awesome time!

We rode this trail today and loved the beautiful fall colors! We started at Danada off of Naperville Rd....loved the scenery, trail width and Herrick Lake! We then connected to Blackwell Forest Preserve via Butterfield for a longer ride (turning in just past Winfield Rd) Blackwell was beautiful, too! We found Two Brothers in Warrenville for lunch but used the GPS to find that and jump back on trail. 20 mile round trip...a great day!!!
