The He-Leo Two Rivers Preserve adjoins a previously owned property called the He-Leo Preserve. The entrance is adjacent to the Rockvale Township Building on Illinois Route 2 south of Byron. Since these properties are on the Rock River and the Leaf River (hence the name, Two Rivers), it offers amenities for boating traffic anda there is a kayak launch, floating boat docks and boat slips. This 48 acre preserve has a picnic shelter, portable toilets, hiking trails, restored oak savannas and wetland areas. It is a haven for a wide variety of birds and other wetland wildlife species.
