If you need to check in during this time, make prior arrangements.
Whale-watching season runs from winter until early spring. However, this season is also the most crowded, and the campground is highly likely to be at full capacity, so if you want a quieter experience, consider the autumn shoulder season. While San Clemente State Beach is a year-round destination, summers are the best time to visit when temperatures are hot and days are long, and there are plenty of lifeguards on duty. If you can’t secure a campsite at San Clemente State Beach, you may have better luck at San Onofre State Beach just a few minutes' drive down the coast.The maximum permitted length for motorhomes and trailers at the RV campground is 30 feet.Each of the two group campsites can accommodate up to 50 campers.Campgrounds tend to fill up fast, particularly on weekends and during the summer, so it's wise to book as early as possible.Campsites can be reserved up to six months in advance on the California State Parks website or over the phone.
