Time Out says
Small, beautiful and dominated by rocky outcrops, El Matador looks not unlike a European beach. Six miles north of Malibu and 25 miles from Santa Monica, it's past just past Leo Carrillo Beach, accessible via a steep gravelly path. Wear shoes and don't bring too much gear. There are no lifeguards or other facilities, so you should be able to find some privacy on the beach; spread your towel in the cupped hands of the rocks—watch out for high tide. Arriving early or staying late should reward you with a memorable dawn of sunset. El Matador and nearby El Pescador and La Piedra beaches collectively form the Rober H Meyer Memorial Beaches. All three are worth a visit. Pony up $8 in the self-pay parking lot or snag a spot on PCH.
