Cardiff State Beach is located just west of Coast Highway and has a small sized, paid parking lot. Street parking nearby on Coast Highway is free. There are bathrooms, showers and an outdoor hand washing station, and one lifeguard tower that is often staffed. The San Elijo Lagoon enters the beach at the north end, and rip currents sometimes occur when the tide is changing from high to low. This spot is very popular for beginning and experienced surfers. Crowds can be heavy, especially during the summer months, but limited parking does limit crowds most of the year. Dogs are allowed on leash.
