Hiking and Boating At Contra Loma Regional Park 

Contra Loma consists of an expansive 780 acres and an 802 acre reservoir for year round hiking, biking, picnicking, and boating.   Hiking trails throughout Contra Loma are all well-marked for novice and more experienced hikers. It is always recommended that you wear comfortable walking shoes and bring water with you, but trails vary from simple, paved paths to more robust and advanced trails off the beaten path.   From Contra Loma, there are trails that can connect the more adventurous hikers to Black Diamond Mines Regional Preserve

The reservoir contains a variety of fish for local fisherman.  Catfish, black and striped bass, bluegill, trout, and red-eared sunfish are in the reservoir throughout the year. However, a Daily Fishing Access Permit is also required and available for purchase at the park entry kiosk.  For boaters, visitors may launch boats up to 17 feet into the reservoir. Only boats with electric motors are permitted. Windsurfing and kayaking are also permitted activities in the reservoir.  

Swim in the Lagoon

Another unique aspect of Contra Loma Regional Park is the swimming lagoon.  The reservoir is actually considered a backup water source for emergencies, so activities are restricted to ones that do not permit physical contact with the water. For swimming, a visit to the lagoon is what should be on your daily agenda.   The swim lagoon is a get-away without having to leave the comfort of Antioch.

Arrival at the lagoon will welcome you to a sandy beach, restrooms, a concession stand as well as a green lawn for soaking in the sun and picnic tables for lunch and dinner.  The lagoon has multiple lifeguards on duty all day and offers free life-jackets for all swimmers who are not confident swimmers. Swimming is limited to hours where there are lifeguards on duty and is not open throughout the year like the rest of the park. 

Schedule A Visit

Contra Loma Regional Park District, located in Antioch, CA is open seven days a week.  Make sure you check the website to confirm hours of operation. However, a general rule of thumb is that the park’s hours are similar to the hours the sun is in the sky.  Summer months have the park open as early as 6am for people who like to catch the early fish in the reservoir or run the trails in the brisk morning air. Closing time is as late as 8pm in the summer and as early as 6pm in the winter months.  Contra Loma is an accessible park – with parking, paved trails, and even a wheelchair lift the swimming lagoon.
