Lake Minnetonka's Big Island was once home to an amusement park that drew visitors from the area. The park featured various attractions, including a rollercoaster, an aquarium, and an old mill ride. These attractions were accessible by streetcar and steamboat, making it a convenient destination for those looking for entertainment.

The amusement park operated for a relatively short period, from 1906 to 1911, but the reason for its closure is not specified in available information, and further details can be found in the Star Tribune.
