This is an amazing getaway camping trip 1 hour and 20 minutes from San Francisco.
These kind of getaways shouldn't be planned many weeks before the trip. So we didn't booked a campground. And from this experience we learn that you don't have to reserve a campground. Just go there - don't panic when you see campground is full sign in the entrance. There are always available spots in there.
This is great getaway. Don't plan, just leave the city! The campground is not actually on the beach next to the ocean. But from entrance of the park, if you follow the road for 10 minutes from the campground (I totally recommend driving there), you are going to arrive the beautiful ocean. Restrooms are so clean. There is hot water and nice showers.
