We were camping at South Marcum so that is where I started. The concrete path was in great shape, just like riding on a sidewalk. A short distance of hard packed gravel was a little rough, but easy to ride. I had to quit at the visitor center because of the rain, but I will definitely be back to finish the trail.

Rode from Harrisburg to Karnak and back today. Great trail. A little wash out about 10 miles north of large tunnel. Not much on trail. Bathrooms at Harrisburg locked. Saw very few riders. A few walkers. One guy on an electric bike with a rifle.
Excellent trail going with a large section that goes through the Shawnee National Forest. The trail is very well maintained and in excellent condition for the entire length except for 1.6 miles that is under repair. The previous reviewer stating the need for a full suspension mountain bike are completely inaccurate. I have done it on 32c tires many times and while this particular section is indeed under repair one you can always dismount and walk this short section and enjoy the scenery. The rest if the trail is in great condition with evenly spaced rest areas, pit toilets, water, trash cans, and ample parking. This area of Illinois is beautiful with many excellent campgrounds and sights seeing
It is a tale of two trails, one Southwest of the tunnel, the other, if it can be called a trail, Northeast of the tunnel. In late September my brother and I road both. Our first day we rode from Karnak to the tunnel, and back again, around 43 miles. That part of the trail is reasonably maintained, with trussell bridges and lush cover from thick forests. It was a long ride, but the hills rarely exceeded a 5% grade. So we expected the trail from the tunnel to Harrisburg to be the same.... It is not. Expect loose crushed stone in many places that 36c tiers will sink into, and 1/4 inch gravel in others to repair the surface, as well as washed out dips on the sides of the trail. Expect to fall approx. 25 feet into snake infested water if you should go off the side when you have to make a quick direction adjustment. (I assume snakes are in the water since we road past a few snakes on the trail, one a cottonmouth that showed us its dental work.) If you plan to ride the Northeastern section from the tunnel to Harrisburg you will need a mountain bike with full suspension. A gravel bike or a hybrid is not enough.
We rode today from Stonefort to tunnel hill and it has some washed out spots and is rough in spots
We started in the back of the South Marcum Campground, followed the path and rode out 11.5 miles around Dam to other side of lake. We saw 24 deer and other wildlife, had the trail all to ourselves, 23 miles round trip.
Tunnel hill south was a wonderful trip! The tunnel was beautiful, take a flashlight. The next day we wanted to ride north, MISTAKE about 2 miles you will see a sign trail damage, what an understatement. We rode another 1.5 miles and hit a spot you had to walk your bike through, we bike for fun and this was not fun so we turned around. 600 mile road trip to ride this trail.
Stayed at Gun Creek Campground. Easily hopped on bike trail at golf course water tower. Trail was fully paved, rode through beautiful wooded sections.
What a great trail. My wife and I have of list of trails and this is one that should be on yours. We rode out of Karnak , we got in night before and stayed at Brothers Main campground. Grate place and right across from trail head. Site had water and power. We were concerned about trail being crushed stone and we had a lot of rain night before. We did 45 miles and only ran into three ruts from run off rain. Had a great time and will do again, we will try and catch the fall colors next time. Thanks state of Illinois for an awesome ride
I biked this trail Saturday from Vienna to Stonefort. Beautiful trail. I wish Illinois would invest in more trails.
