Founded in 1960, the Three Sons has been a staple of Milford, IA retail. From Herman and Emil Richter, owners, was born the University of Okoboji, a ficticious university that calls the entire Iowa Great Lakes the campus of the U of O. Part of the experience of shopping the three sons, if walking the old battered floors, and taking a trip upstairs for half price, plus a buck. Brands you would expect in Milford Iowa are abundant, such as Patagonia, Oakley, Under Armour, Tommy Bahama, and more. There are currently 2 other stores; one at the amusement park, and another near the Regal Beagle called the bridge store. No self-respecting visitor to Okoboji leaves without visiting one of their stores.

Mother Nature's is an American Restaurant Style bar/restaurant/lounge. Mother Nature's has been a local Estherville bar and grill since 1978. Stop in for the best burgers and steaks in town!

Spirit Lake Spillway

Looking for some entertainment with the kids on a nice summer weekend, come check out the Spillway. The Spillway connects Big Spirit Lake to East Lake Okoboji allowing overflow water to move from Big Spirit Lake to the chain of lakes. This helps keep water levels under control on Big Spirit.

Depending on the time of year you visit, you may see hundreds, if not thousands of fish, mostly carp swimming upstream, it’s a neat site to see.

While you are here, you can launch your boat for a day on the lake, or you can visit Orleans Beach next door. Or you can grab lunch at the Spillway Drive In.
