The Buffalo Viewing Trail is a 3.6 loop hike, just outside of Elwood, Illinois.
The trail features chances to see bison, and scenic wild flowers. The Buffalo Viewing Trail is in Midewin National Tallgrass Prairie, and is open year-round. Dogs are allowed on this trail but must be kept on leash.
Old army bunkers are scattered along the trail. The trail winds through a prairie, so the grass is often mid-calf or knee height. Be weary of ticks - for both you, and your dog.
