There is ample parking at Zuma Beach in the county managed parking lot.
While other beaches mostly have day rates (Winter $3.00 to $8.00; Summer $3.00 to $10.00) on Zuma there are now meters which charge by the 10 minute increment, up to a max charge for 90 minutes. The prices are on quarter per ten minutes or $0.25/10m.
Fees are used to fund the beach cleaning and facilities such as restrooms.
NO overnight parking is permitted at Zuma Beach or any of the other LA county beaches, with the exception of RVs on Dockweiller who have bought overnight tickets. Note that the Dockweiller 62nd Ave lot is closed until August 2020 but the Imperial Hwy lot is still open.
