Another somewhat-hidden gem of a nature preserve in the area, Berkeley Prairie Forest Preserve features some of the nicest prairie grasslands in the neighborhood (rivaling Prairie Wolf). This is a great spot for bird watching and finding local beneficial insects. There's a slightly-raised grass path that goes around the prairie, which is usually in pretty good shape as long as you wait a few hours after a rainfall. The path cuts through some oak forest and parallels some wetland along the north branch of the Chicago River. It can be a little tricky getting to the trail. There's a fairly-obvious entrance on Ridge Road, but there's only enough room there for one vehicle. I'm not entirely sure if you're even allowed to park there, as it seems like it is the vehicle entrance for park maintenance (I've never stopped to read the signage there). There's actually a "commando" entrance to the north just past Ryders Ln. on the non-contiguous bit of Berkeley Rd. - you'll see a dirt pull off and a small unofficial path that leads to the Berkeley Prairie trail. The street is narrow here, so this pull off is about the only place you can safely park - there's probably enough room for three cars. If these spots are taken, but you really want to walk the trails, there's plenty of parking at Olson Park further north on Ridge that is about an 8 ~ 10 minute walk away. read more
