Welcome aboard the streetcar steamboat Minnehaha. Today Minnehaha sails from Excelsior and Wayzata, MN every weekend from late May through early October, providing a glimpse of Lake Minnetonka's storied past. We welcome an average of 10,000 passengers each year but it wasn't always this way.. for more than 50 years she lay on the bottom of the lake, this lake. Come experience the take of "the little steamboat that could."
