A small city park that is home to the Prospect Park Water Tower (commonly known as the Witch's Hat), which is located on one of the highest points in the city. The top of the tower has great views of Minneapolis and Saint Paul, but unfortunately it is only open on one day of the year, typically the Friday after Memorial Day from about 5PM-8PM. If you actually happen to be visiting the city on that day, don't pass the opportunity to climb up to the top of the tower.
