San Onofre State Beach – San Mateo Campground, California (Guide + Reviews)
Overview
San Mateo Campground sits inland from San Onofre State Beach, surrounded by coastal sage and oak groves just east of the Pacific. It’s the quieter, more sheltered sibling to the oceanfront Bluffs Campground — offering larger sites, hookups, and a short hike or bike ride to legendary Trestles Beach. With warm weather, open skies, and a convenient location near San Clemente, it’s one of Southern California’s most dependable beach-adjacent camping options.
What Campers Are Saying
Overall vibe: “Relaxed and clean.” Campers appreciate the larger sites, reliable facilities, and easy trail access to the coast. It’s not right on the sand, but it’s peaceful, well-maintained, and great for families or groups heading to the beach during the day.

- Full amenities: showers, flush toilets, and hookups.
