Tunnel Hill to Main Brothers Campground

Highlight • Structure

Karnak is not the end of trail but it is the last point on the trail to camp. The Main Brothers camp ground is pretty simple but it is the only campground at the south end of the trail. The campground is clean and in the main campground there are spots for tents.

Tunnel Hill State Trail

Highlight • Trail

The Tunnel Hill State Trail in Southern Illinois winds it's way through the Shawnee National Forest and down into the the Ohio River Valley. A well maintained crushed limestone surface can be hiked or ridden on bike. If bicycling the trail can be ridden on any style bike. the highlight of the trail is the 350 foot long tunnel at Tunnel Hill. bring a flash light or bike light as the tunnel is dark. This trail is worthy of a trip as it combines great cycling with beautiful scenery. I encourage all to check it out.
