The Okoboji Lakes region in Dickinson County in northwest Iowa encompasses a chain of natural glacial lakes known collectively as the Iowa Great Lakes, centered on West Okoboji Lake, East Okoboji Lake, and Spirit Lake. West Okoboji is the jewel of the chain — a spring-fed glacial lake with an unusually clear blue-green color and depths reaching 136 feet, making it one of only three blue-water glacial lakes in the world according to regional geologists. The lake and its surrounding resort communities of Okoboji, Arnolds Park, and Spirit Lake have served as Iowa's premier summer destination since the 1880s, when railroad excursion trains first brought Des Moines families to the lakefront. Arnolds Park Amusement Park, one of the oldest operating amusement parks in the United States, sits directly on the West Okoboji shoreline and features the wooden Legend roller coaster (built 1930) alongside modern rides, a midway, and lakefront concert venues. Public beaches at Emerson Bay, Triboji Beach, and Pillsbury Point State Park offer free swimming access to the lake. Pontoon boat, kayak, paddleboard, and personal watercraft rentals are available from multiple marinas along the West Okoboji shoreline throughout summer. The Iowa Great Lakes Maritime Museum in Arnolds Park documents the region's boating heritage. In winter, the lakes freeze solidly enough for ice fishing shanty communities, snowmobiling on the ice surface, and cross-country skiing on groomed park trails around the lake perimeter.
