From ultimate local through hiking to an easy century ride on the bike, the following 4 longer Southern Illinois trails should cater to any outdoor needs that you desire.

Longer Southern Illinois Trails


Trail 049

I’ve included Trail 049 in the longer Southern Illinois trails list because it is part of a loop system that I do each year for fitness. This trail loop will allow you to hike 10+ miles. You start at East Trigg Trailhead and head for Millstone Lake on River to River, then you’ll take Trail 049 and head into Jackson Falls. You’ll eventually loop back to the River to River Trail near the Tin Whistle and then make your way back to East Trigg Trailhead.

There are a lot of great sights along this trail. There are plenty of bluffs, scenic creeks and rolling hills. It is advisable that you pack adequate drinking water, snacks and wear proper attire and footwear for a rugged hike. Expect to cross multiple creeks, some of which may be fairly high pending the amount of rain the area has had. Mosquitoes, ticks, poison ivy and venomous snakes might be present in the area. Stay on the trail and respect private property.

This trail is suitable for hiking, overnight backpacking, horseback riding and quite popular for trail running. This trail has been featured multiple times as a part of the No Sleep Adventure Race that has occurred annually in the Shawnee National Forest. Some areas have been damaged quite severely by jeeps and ATV traffic. You may need to get slightly off trail to avoid hiking/riding in these particular areas. The damage is especially severe in between East Trigg and the Tin Whistle which is a tunnel that goes under the Railroad Tracks.

Tunnel Hill State Trail

Another of the better longer southern Illinois trails is Tunnel Hill State Trail. This trail is often used by cyclists and runners. The trail was previous a rail-road line and has since been converted into what is known as a rail-to-trail. The trail has a low elevation grade for the most part but does include some minor hills. The trail is wide enough for cyclist/runners on both sides and is mainly made up of crushed limestone with some areas having gravel or concrete. This is an out-and-back trail consisting of about 45-50 miles in total length starting at Harrisburg, Illinois and ending at Karnak, Illinois. The Tunnel Hill State Trail headquarters is located at the Vienna City Park. This trail is managed by the Illinois Department of Natural Resources.

This trail offers cyclists and runners many great sights. There are areas with bluffs and portions of the Shawnee National Forest along the trail. The River to River Trail crosses Tunnel Hill State Trail. There is an actual tunnel (located at Tunnel Hill, Illinois) that you can ride through and several trestles that you ride across along the trail. Just past the tunnel heading towards Vienna, the Sandburn Junction, a historical building offers bike rentals, snacks and has a nursery attached to it. Tunnel Hill State Trail is very safe for the most part. However, riders and runners should watch for other cyclists and trail users to avoid collision. There are dangerous bluffs present. Venomous snakes, poison ivy and ticks have been seen in the area. Please always stay on the trail and respect private property.

Tunnel Hill State Trail is suitable for cycling with mountain bikes or bikes with tires suitable for loose gravel and limestone. Road bikes can be used but the surface may be challenging for these bikes. The trail is also suitable for runners, hikers and pet walkers. All children should be supervised by responsible adults as there are dangerous areas present. Tunnel Hill State Trail is a day-use only trail meaning that you may not use it at night. There is camping availability at Main Brothers Campground in Karnak. Equestrians and motorized vehicles are prohibited from being on the trail. Horse riders may cross the trail where the River to River Trail crosses in-between Vienna and Tunnel Hill. Please yield for horses if they are crossing to ensure safety for you and the rider.

Longer Southern Illinois Trails


Heron Pond to Wildcat Bluff

Heron Pond to Wildcat Bluff is a great addition to the longer southern Illinois trails list because of its unique and diverse environment for the area. Heron Pond and Wildcat Bluff are a part of the Cache River State Natural Area which is made up of swamp and marsh environments that while look to have come from somewhere in Louisiana, were actually natural conditions covering much of the region many years ago before previous European settlement destroyed most of the environment. This 10-15 mile out-and-back hike offers foot travelers the experience to see an ever changing diverse natural environment each step of the way. The hike can start at Heron Pond or Wildcat Bluff; both areas have adequate parking available.

As stated, this is a lot to see along this trail. If starting at Heron Pond, expect to see swamp environments at the start, leading to a huge champion Oak tree. Then you’ll enter a native hardwood forested environment seeing signs of previous settlement. As you enter what is known as Little Black Slough, there are swamps and bluffs sharing the area with a diverse set of plants, flora and wildlife enjoying the natural area. Imagine an ocean of swamp in front of your eyes. Little Boss Island is host to a small cabin that once house 8 people and now serves as a wildlife shelter for different types of critters. Once you get into Wildcat Bluff, you’ll be in awe to all the awesome bluffage around you and even get to experience a great overlook of the countryside. Dangerous areas and hazards exist along this trail including cliffs/bluffs, venomous snakes, poison ivy, ticks and other biting insects and creek crossings. During flood and heavy rain conditions, crossing the creeks will likely be impossible. Please respect private property and stay on the trail.

This trail is suitable for hiking or trail running only. This is a day-use only area with no camping available along the trail. Most of the trail is wide and easy to follow. As long as you stay on the trail, you shouldn’t get lost. You will cross two active railroad crossings and two creeks. Bicycle racks are provided at Heron Pond. Maps and brochures are also available at Heron Pond. Heron Pond has two vault-styled restrooms available for trail users. There is no running water (besides creeks if not dry) along the trail. Responsible adults should watch children at all times if using this trail. Because of the swampy conditions present, snakes (including venomous snakes) will be presented here more so than other trails and often visible to trail users. If you encounter a snake, give it room and do not handle it to avoid an unwanted interaction. Hunting is allowed in this area during legal hunting seasons. This trail is for hiking only – bicycles, equestrians and motorized vehicles are not allowed on this trail.
