This place is a hot spot and tough to book so make sure you do it far in advance. The area sits up on the Carlsbad cliffs, and there are stairs that run down to the beach about every 1/4 mile or so, some aren’t open though due to damage. Best sites sit on the cliff side where you can over look the ocean, otherwise you’ll be hearing the cars off the road, but any spot is nice as long as you plan on spending your days on the sand.
The spots are separated by large bushes (mostly) but still can get pretty hot in the day so be sure to bring shade. Some spots now have hook ups, and they vary in depth from large enough for a motor home to small enough for a tent.
Where you drive in is the middle, there are washers and dryers there, a store (open in the spring and summer), and rentals for bikes and surf boards. The bathrooms along the campground have showers so be sure to bring cash for tokens.
Other important notes: beach shore can be very rocky in spring time due to tidal patterns, there’s a dump station for RV’s, campsites generally just have fire rings and picnic benches, squirrels can be a bit of a pain, and the ONLY real issue I can find, there is a theft time to time so keep your stuff hidden or locked up. They’ll go for your cooler, generators, and anything they see.
