An excellent primitive campground site, Cabrillo Harbor has four designated campsites, but only sites 2 & 3 are reasonable. Site 1 is wedged in between a rock with no clear spot for a tent, and site 4 appears to be a giant boulder. The harbor offers decent protection from waves/wind, but strong currents out of the northwest will pose challenges to your anchoring system if travelling by boat. There is a lone, well-established chaparral bush in the center of the beach which offers a sturdy tie-down for kayaks or a stern anchor. We could not find a latrine onsite, but there are several boulders to hide behind when nature calls. Although fire restrictions were in place at the time of our visit, two fire pits with grates were on sites 2 & 3. There was no picnic bench or other facility there to use, so best to bring your own table or flat surface for meal preparation. The tides are drastic at Cabrillo, meaning that high tide will totally cover the sandy part of the beach and low tide will reveal about 35-40 feet of sandy beach about 10-15 feet beneath the elevation of the campsite. Most of the campsite area consists of rounded stones roughly the size of golf balls, and closer to the cliffs you will find matted grassy areas or relatively flat patches of dirt which are perfect for tent stakes. We encountered strong undertow currents in the afternoons at Cabrillo, but snorkeling opportunities exist particularly in the mornings near the rock outcroppings as the water is beautifully clear and turquoise. You can see clearly to the seabed at depths around 35 feet or so (you can actually view your anchor lifted come retrieval time). If you are looking for cell service, forget it. If you are looking for wildlife, particularly dolphin, sea lions, or flying fish, this is the place to spot it. We had zero problems with wildlife getting into our food or trash, but did see little pawprints on top of our secured food container one morning, so best to keep things secure at night. Overall, Cabrillo Harbor is a great location and a treasure for visitors willing to reach this place to experience the best of Southern California's natural environment.
