Great day use area, too.
Point Mugu State Park ( Sycamore Cove has a great day use area on the beach across the street from Sycamore campground. Lots of tables or sand for blankets and umbrellas. About 20% of the tables are in the shade of trees. One cool benefit, the day use fee is daily or hourly $12/day or $3/ hour. We bought two hours, fixed a nice lunch, and took a walk on the beach. The beach drops off, gets deep quickly, not the safest waters but swimmable. There are lifeguards. Bathrooms are pit toilets.
Note: Both Sycamore campground and Thornhill Broome campground up the road are under “Point Mugu State Beach” when you want to make camping reservations.
