Mile Square Regional Park explains Fountain Valley's open-space map
Mile Square Regional Park gives Fountain Valley a large county park with lakes, fields, golf, picnic areas, archery, and city recreation next door.
Mile Square Regional Park is a big reason Fountain Valley feels more open than a map of Orange County might suggest. The 607-acre park has two fishing lakes, picnic areas, shelters, ballfields, soccer fields, a nature area, and two regulation golf courses.
There is also a city layer beside the county park. A leased area along Brookhurst has Fountain Valley recreation facilities, including a community center and sports courts. The archery range adds another unusual piece, with public lanes, targets, shade, bow racks, fencing, and a safety berm.
Use the park as a shared city-and-county place. That means the right rule depends on what you are doing. Fishing, archery, golf, rentals, parking, and lake use may each have their own hours or fees, so check OC Parks before making plans.
It also anchors local directions. People may talk about the golf course, the lakes, the archery range, or the city recreation area and still mean the same broad park landscape.
