I have more, I wasn't going to post them, but my husband twisted my arm. There are so few sites we can fit into now in the California State Parks and Beaches as well as national parks that I hesitate to let the cat out of the bag.
This is one of our favorite places, Seacliff State Beach. We love the view and the beach access. It's also very close to Monterey. We're in site 5, but the site numbers don't really matter because all the sites are the same, except for the accessible site, which is completely paved.
If you're lucky you can see pods of dolphins swimming along the shore.
This is our other favorite place, Yosemite National Park. We're in a double site which requires there be at least 7 people in your group, but no more than 12.
