Our family had a great time camping at site number 23 in San Mateo campground. Electrical and water hook ups, a great view, and a lot of space to enjoy this one of a kind Campground. Your camp ground receipt permits you to drive down to San Clemente State Beach and park feet from the water with no extra charge. Great mountain biking Just off the main road. Having an E bike allows you to zip back-and-forth to the world famous Trestles Surfing beach, or you can park on the main street and walk in about a quarter mile to this beautiful beach. This camping area is a couple of miles across from the Marine base, and when we arrived there was some live artillery training during the daytime. At first we thought there were thunderstorms in the area🤓
