Castle Rock Park is the largest park in the growing Heights neighborhood, attracting people from all over Billings. This 25-acre park in the Billings Heights currently has large, open playing fields, tennis courts, a splash pad, and a pond, with much opportunity to expand. The Park was originally built in 1982, but was only partially finished. An updated master plan for Castle Rock Park will be like a road map for adding new amenities and features, as well as improving what’s already in the park. An updated master plan would better suit the needs of both today’s Heights neighborhood and the greater Billings community.
