Casa Grande Ruins National Monument is open every day of the year, except Thanksgiving, Christmas, and Independence Day, when the monument will be closed. The park has a gate that will open at 9 am daily. During our busy season of October 1 through April 30, the monument will close at 5 pm. During the summer season of May 1 through September 30, we will close at 4 pm. The gate closes 15 minutes prior to closing, with access for exiting the park still available on the outgoing side. All visitors will leave the park, including parking lots, picnic area, visitor center, and historic area, at closing.
