All grass. Best for walkers not bikes.
It is July 2026, and the 294 closure on the trail is not open to use. Please update in the review section.
Although the meticulously maintained 8-foot wide asphalt trail is short, one must cross W Forest Home Avenue twice. The traffic was fast and constant. I was lucky enough to attract a courteous driver who stopped for me, so I could make it across safely. Not a good trail for the young ones. The rating of the trail would have been 5 stars, but the traffic crossings brought it down a notch.
This 8 foot-wide asphalt trail was beautiful when I first rode it several years ago. The 3 sections of trail are connected by roads. One must cross 2 busy roads to get to the middle section from the southern section and there is no signage to guide you. The southern section is also poorly maintained; the grass is not mowed on either side of the trail and the tree branches and bushes overhead make the 8 foot wide trail seem smaller. I still bike this trail quite often, because it is a safer and a more scenic route to travel from my house to downtown.
This 8 foot-wide asphalt trail meanders through urban neighborhoods. Although the trail is broken up in a few sections by roads, there is plenty of unique artwork to see. My favorite ride in the city!
We rode the trail northbound from Palmer Park. One caution I'd offer is it can be confusing because the signage reflects the Ice Age Trail more than the Spring Brook Trail. Possibly because this area seems to be convergent with several trails, including the Peace trail heading south (another very nice ride). Back to the northbound ride; once you go under highway 14, you'll find the trail splits, showing the Ice Age Trail turning left/westbound, and another trail (unmarked) heading due north. We decided to investigate the unmarked trail and found it very pleasant. The trail ended at East Rotamer Road, a short distance east of the left trailhead had we taken the other option by highway 14. We decided to ride E. Rotamer Rd. Westbound a short distance to the other trailhead and take it back to Palmer Park. Travel on Rotamer road was very easy. Designated bike lanes and light traffic helped considerably. In the end, the loop was a wonderful, enjoyable ride. As an aside, taking the trail south from Palmer Park, in the area of the Rotary Botanical Garden, you'll find the Peace Trail. One final note: there are several trail options in area; you might consider keeping your trail app active. My wife and I will definitely be returning.
8/2/26 drove over an hour to experience, well lets say "much ado about very little" While from the trail preview it appeared interesting, this is one trail we'll not be returning to. Sorry Beloit, we bailed and went to Janesville's Ice Age Trail.
I have been riding this trail for three years now. (2024 - 2026) No more. The gravel has, in many places, turned dusty, deep and slippery. You might enjoy the gravel on a gravel bike. I ride a skinny tire road bike. OK for the first two years. Not OK this year.
This well maintained asphalt trail is a nice extension of the New Berlin Trail.
At the midway point, one must exit the trail and ride down to 116th Street, then ride back up to the trail on the other side. What would it take to extend this trail further east?
Rode the Blackwell Forest Preserve section on July 25, 2026. Despite hot temperatures, the shaded stretches kept us cool. The condition of the crushed limestone surface was smooth but dusty. The only glitch was that several times we rode around a bend only to be run off the trail by groups riding two or three abreast. First time that’s happened In 2000 miles of biking. Wouldn’t keep us from going again…outstanding trail.
Bike type: Hybrid (Specialized Sirus 2019)
Conditions: mid-70's, light breeze, dry
Segment biked: Just south of Algonquin to Barnard Mill Rd (north of McHenry) = 40 miles
I started my ride around 9:30am on a July Friday. I had biked a few miles of the trail just north of downtown Algonquin before, the rest was new to me. Perfect conditions motivated me in every way. Perfect temps, full sun, and breeze kept me going for my longest ride since 1997.
The entire path that I rode was asphalt. There are a couple of deviations through downtown areas when you're on sidewalks or streets. But everything was paved. Riding from town to town has always been a favorite, but the Prairie trail gie you even more than that. North of Crystal Lake you'll find miles on end of straight path and very little to see except nature. There's also Sterne's Woods, which really threw me for a loop. Can't say I've ever seen signs that tell bikers to dismount. Then you find out why. There are several hills back here to test your fortitude. At least three hills look to be close to a 45-degree angles. If you're riding these as I did, be careful and make sure you're only tempting them in optimal conditions (dry, no wind). Just coasting pushed me close to 40mph. These hills are as tough as they come to climb in Illinois. Algonquin, Crystal Lake and McHenry all offer pitstops if you need one. I saw two other parking lots away from the towns with benches and bathrooms. I had read from other reviewers that the path north of Barnard Mill Rd was gravel and dicey, so I didn't tempt that. My hybrid tires can hold their own, but it only takes one sharp piece of gravel to strand you far from your starting point. All in all, this path is a 10 out of 10 in my opinion. It's extremely well kept up, very diverse, ridable for any type of bike, with amenities and beauty along the way.
