Nice quiet spot without much traffic in the winter months. Has some small hills and valleys to give you a few short moments of climbing.

I camped at Big Rock Campground (just north of this) and there is a 1.3 mile trail that connects to this trail. Campground and trails were average. Siegler lake is a beautiful catch/release lake, saw many bass/panfish.. and a big ol' carp. The trail around it was labeled as 'gravel' - it's about 15% gravel, 60% dirt, and 25% grass. The offshoot trail up the hill is barley mowed overgrown atv tracks. Trail to the campground is basic crushed limestone. West Savanna Trail is a bit overgrown for a mowed path. 2 pieces of wood from the bundle of wood i bought were half burnt already, lol. As a whole it was an ok camping experience and ok trails. I'll upload a pic of the map they had at the campground.

Nice short trail for northern Illinois. Pleasant and a little wild. Walked it in spring and enjoyed tracking down the song of frogs.

Refreshing to find this little park amongst all the fields. Some limestone trails, but there are several stretches of mown grass for those that like a bit more variation in their run...not to mention softer foot falls. Looking forward to exploring more of the area soon.

Lots of coyote / dog droppings along the crushed limestone areas of the trail, near the parking lot. I would rate it higher if I hadn't hiked it when it was 93 F.
