This is a great trail that offers plenty of options for all level of cyclists. The trail is well maintained but there are short sections where gravel was put down versus crushed limestone and could be a challenge for those riding a bicycle with skinny tires. Water was available on the trail but all the air pumps at the trailheads were unusable due to issues with the pump heads but the restrooms were open. There is tree canopy along 95% of the trail which made all the difference on an unseasonably warm day for May. There was plenty of wildlife to be experienced especially as we launched back to our car at sunrise which included deer, box turtles, chipmunks, lizards and of course snakes which included some of the poisonous variety. We spent the night in Harrisburg and enjoyed a superb gastro experience at Morello's with an extensive menu and excellent wait staff. In my opinion, I would avoid the section of the trail from Harrisburg to El Dorado as it is poorly maintained, exposed to the sun and eventually turns into a road. Enjoy the Tunnel Hill Trail experience!

My husband and I rode from New Burnside to 4 miles past Tunnel Hill—about 22 miles. The tunnel was cool, literally. Ride is Almost entirely wooded—saw a snake, possum, turtle, otter (I think) butterflies and birds. A great day!

We rode from Vienna to Tunnel Hill & back. A beautiful, scenic, peaceful ride. 20 miles round trip. Don’t miss this ride!!!!

Just started walking this at lunch and it great. Flat mostly shady, clean and all concrete

We went riding on a beautiful day! We began on the end near river, and it was clean, sunny, and had some beautiful views. My 3 boys really enjoyed the ramps in the skateboarding park in Nobel Park. Afterwards the trail became wooded with crushed rock and was so peaceful and scenic. We passed by the disc golf course and the trail ended with an optional loop that I was told just became an extension about a year ago! It had hills and some bumps for fun. There is even a mountain bike practice area along this loop! I hope it generates more use once people find out about it.

Stayed at the Main Brothers camp ground in Karnak, IL which is about 2 miles from the official trail head. The primitive camp sites at main brothers were right next to the road. Full trail is 110 miles plus the two I road to the trail head. Trail is more rough than people say. Choose the right bike. Trail north of Harrisburg is single track so 15 miles round trip was slow going and full sun. Bring water but know there are a lot of water stops. Get food in Harrisburg if you ride that far. There is only one true tunnel so know that and expect to enjoy a lot of nature.

Wooded, shady, well maintained densely packed fine gravel. Only noted one place for snacks, so bring sufficient water & snacks. Clean rest stops along the way.

95 degrees on the way to the trail, 75 degrees on the trail. Shaded 95%. Beautiful scenery Nice path Very low grade Plenty of deer If you stop the mosquitoes will carry you away so use your Skin So Soft from Avon Works great Smell great

My wife and I took the trail from Vienna IL. to Harrisburg IL. for our 29th anniversary, Uh lala how romantic (he says with a wink). 34 miles one way. We packed overnight cloths and stayed in an Airbnb, "The Apartment at 217" in Harrisburg. Loved the apartment and our hosts. Stopped in Stonefort on the way up and ate lunch at "Bucketheads", a must stop. Nice staff and good Cajun food. We've ridden from Karnack to Vienna before so we have completed the whole trail. The ride from Vienna to Tunnel hill is the prettiest part. 9.3 miles from Vienna to the Tunnel. When you get to the tunnel you can feel the cool air and it feels great on a hot day.
