Get away from grim winter weather at the Nicholas Conservatory & Gardens, a compact tropical wonderland. The conservatory features numerous tropical plants, a small pond system stocked with koi, orchids, and a balcony overlook. In nice weather, take a walk along the riverside trail that passes the conservatory along the Rock River.
