Contra Loma Regional Park & Swim Lagoon

Contra Loma's 780 acres include an 80-acre reservoir for year-round fishing and a lifeguarded swim lagoon for summertime swimming. Enjoy these attractions along with year-round hiking, biking, and nature study at this Contra Costa County oasis. The lake's swim lagoon has a sandy beach with restrooms and a concession stand. Shady picnic areas on a green lawn are accessible to the disabled. Alcohol is not permitted anywhere in the park. Swimming is permitted in the lagoon only, in the summer when lifeguards are on duty. There is a beach access fee. The reservoir contains catfish, black and striped bass, bluegill, trout, and red-eared sunfish for fishing. A Daily Fishing Access Permit is required and can be purchased at the park entry kiosk.
