Located at the mouth of the historic Fox River in downtown Oshkosh, where the water opens up to the breathtaking views of Lake Winnebago, the Leach Amphitheater is a spectacular venue for community festivals, live concerts of all types, company outings, and large-scale sporting or fund-raising events. A romantic gazebo overlooking the lake is a stunning setting for weddings, anniversary parties, or other more intimate gatherings.
