    I've been to this park personally and can attest to its beauty. Located along the Illinois River, Matthiessen State Park offers leisurely hiking trails, water views, and forests to explore. Make sure to stop by the canyons, and bring water shoes because you might find yourself wandering through some puddles.

    The 5-mile trail includes lightly wooded sites and wetlands to explore, while the hills (or kames) in this area were formed by glaciers long ago. This is an easy hike for a less athletically inclined person (like me), but it still manages to be fun all around.

The main 9.5-mile loop, complete with steep inclines that ensure a good workout, shows off incredible limestone terrain. Hike, bike, and explore the trails, but be careful venturing off the main path because it can be hard to rejoin the loop.
