San Mateo Campground sits 1.5 miles inland from the Pacific Coast Highway, offering 158 sites with electric and water hookups within San Onofre State Beach. Managed by California State Parks, the campground requires advance reservations and fills quickly, particularly during summer months when surfers claim many sites for multi-day stays.
The campground spreads across several loops with mature trees providing privacy between individual sites, though the central areas remain open. lordIrm notes it's "pretty chill" but warns "if you want complete peace and quiet, this isn't it" due to proximity to Camp Pendleton. Military training exercises create distant artillery sounds during daytime hours, and highway noise from I-5 carries through the night when large trucks pass.
A 1.5-mile hiking trail connects the campground to Trestles Beach, popular with surfers but requiring a moderate walk over rolling terrain. Your campsite fee includes day-use parking at San Clemente State Beach Campground and Bluffs Campground — San Onofre State Beach, allowing beach access without additional parking fees. E-bikes are common here for the beach commute.
Shower facilities require tokens purchased with cash—typically two tokens provide adequate hot water. Brad E. observed that "bathrooms and shower area is cleaned and sprayed out every morning." Cell service varies by carrier, with Verizon particularly weak, though some campers successfully use Starlink in the open central areas. Ants are prevalent throughout the grounds, requiring careful food storage.
The campground works well for RV campers seeking hookups near the coast and surf enthusiasts willing to hike for beach access, though those wanting immediate oceanfront camping should consider alternatives closer to the water.
