Wilderness Landscape & Natural Heritage
Cucamonga-Guasti Regional Park is a popular multi-use regional park located in Ontario, California, within San Bernardino County. Spanning approximately 150 acres, the park serves as a vital urban oasis providing a wide range of recreational opportunities including swimming pools, multi-use sports fields, picnic areas, playgrounds, and a lake for catch-and-release fishing. The park features two large reservoirs stocked with trout and catfish, making it a favored spot for anglers of all ages. Its geography consists mostly of flat terrain with landscaped areas suited for family gatherings and community events. Historically, the park is named after the Cucamonga Guasti district, linking it to the region's agricultural past and early vineyard cultivation. Outdoor enthusiasts appreciate the park's well-maintained facilities, including aquatic centers that host swim lessons and water aerobics, as well as multiple tennis courts, basketball courts, and baseball diamonds. While it is not known for wilderness or hiking trails, its setting provides important green space for residents in a heavily urbanized area. Visitor appeal includes its close proximity to major Southern California metropolitan centers, affordable admission to the pools, and accessible amenities that cater to families, sports teams, and casual day visitors. The park is managed by the San Bernardino County Parks Department and is especially busy during summer months and holiday weekends.
