Flat, minimal hills, and winds throughout the city! Very pretty through wooded areas. Offers a great escape for bikers! Well-maintained. Plenty of room to pass others and even ride alongside friends.

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.

Trail was in great condition with packed fine rock. Thought maybe all the rain in spring of 2019 would cause washouts, but surface is in great condition.
Trail south of Vienna is flat and little traveled, I just met one couple in 12 miles. Need insect repellent south of Vienna as the area is swampy.
Trail north of Vienna is uphill all the way to the tunnel, then downhill to the north. There is a little store open at New Burnside just south of the tunnel.

Took the family of five (3 kids ages 6-12) and had a great experience! We took lots of photos along the way, even stopped for ice cream in Sandburn crossing.

My husband and I just stayed at South Marcum campgrounds. We rode the bike trails there, at North and South Sandusky and also Wayne Fitzgerald State Park. We enjoyed it very much and will camp again just to bike there. Most of the trail is paved. We saw deer and baby fawns, turkeys, and even a groundhog.

My husband and I started at the Tunnel Hill Trailhead and rode south 25 miles to the Wetland Center and then back. It was a beautiful ride. We were impressed how well it was maintained. A fallen tree that we had to climb over on the way out was already cut and pulled off the trail on our way back.

At least one snake, five deer, several hawks and what I thought was a very challenging ride since I rarely do 46 miles. The washboard effect could be noticed from Karnak to the wetland center head to the center.

My sons and I still loved the challenge.

I rode from Vienna up past the tunnel on a crisp spring day in April on my hybrid bike and loved every inch. Make no mistake, the gentle uphill grade to the tunnel may seem Slight but it took its toll on me. GREAT ride

I have only ridden from Vienna to Tunnel Hill and back but I did drive down to the Wetlands Nature Center at the southern end as well as go to Karnak and check it out. Even had lunch at "Our Place Deli". I wish I would have given myself more time and got to actually Bike the whole thing but I will be back for sure to enjoy the whole experience. It is easy to see why people love and care for this trail the way they do. I will give myself at least 3 days on the trail to fully enjoy it next time, especially the southern end. It is a shame there isn't any campgrounds listed close by on the northern half.
