Quiet Campground. Beach Camping (if you reserve). Serene Central Coast. Surfing.
Take the 101 North out of LA and follow it till it meets back up with the 1 just south of Lompoc where you make a left turn onto Jalama Rd. If you forgot supplies, continue to Lompoc where you can buy whatever you need.
Follow the winding road all the way to the beach, where your only option is the campground. The Jalama Beach Store is known for its burger, so stop in during dining hours for a bite.
Head to sbparks.org to make reservations.
