As the oldest park in the city parks system, Blanchette Park has also seen many changes through the years. It has always been a gathering place for the community, however. Today, residents head to Blanchette Park to swim in the aquatic facility, which is open between the end of May and the middle of August each summer. Children must be 12 to attend by themselves. Memorial Hall in the center of the park, is a facility that can be rented for everything from a pancake breakfast to a reception. Rooms can be rented individually. Rau Garden is another popular outdoor garden that can be rented for outdoor weddings. The park also has baseball diamonds, a football field, horseshoe courts and tennis courts. Bum's Hollow is a natural amphitheater that is used for concerts in the summer and for sledding in the winter. The City of St. Charles Parks and Recreation Department's Administrative Center is located within Blanchette Park. Visitors can reserve facilities in any of the city's parks by calling the administrative center at 636-949-3372.
