Louis M. Groen Nature Preserve
The Louis M. Groen Nature Preserve, an Otsego County Park in Johannesburg, contains two lakes, 20 miles of trail and a lot of history, including ties to McDonald’s Filet-O-Fish sandwich. The preserve is crisscrossed with trails, many of them old two-tracks that are marked with 86 numbered junctions. The trail system is shared by day hikers, mountain bikers and equestrians. In the winter it’s a destination for snowshoers and cross country skiers.
