Okoboji Boat Works is home to "The Fish Shack" and "The Inconvenience Store". Formerly a marina of thriving boat sales since 1890, OBW now offers up many different rentals, a 24 hour gas dock, excursion boats, and more. I remember the days as a child of fishing for crappie and blue gill here and along the docks of Smith's Bay. Though the scenery has changed, the outstanding fishing has not.
Located at the Bedell Family YMCA in Spirit Lake.
The Climbing Tower offers 5 different "courses" offering different levels of difficulty, some easy enough for my 4 year old to enjoy and some are quite difficult. This offers kids a great activity to keep themselves entertained while having fun and staying active.
If you are looking for a place to catch a bunch of fish in a short period of time, the dock in Minnewashta right off of Sawmill Park in Arnolds Park is the place. Fish with a worm or throw a crank bait, you can't go wrong. This spot located in the center of the lakes area allows you to bring your children to play on the nice equipment, or have a family gathering at the recently remodeled shelter. These waters are well known for perch, bluegill, pike, crappie, walleye, yellows, and smallmouth and largemouth bass. With two different places to launch a boat, Minnewashta is a great place for some family fun.
