Formerly known as the Nautical Nature, Preston’s Pearl is the Park’s premiere attraction. This new enclosed pontoon boat increases the passenger capacity of the previous touring boat and has an upper deck for outdoor viewing. Cruises are offered on weekends from May through October, and passengers will learn about the area’s history and wildlife within Moraine State Park. Preston’s Pearl also offers environmental programs, brunch and dinner cruises, private charters for business meetings, seminars and parties. Tickets can be purchased through their website.
