Moonstone Beach is one of the few genuinely beginner-friendly surf spots in Humboldt County, with a wide flat beach and sandy bottom producing mellow waves. Despite the name — moonstones and agates are found on the beach itself, not in the surf zone. A local surf camp operates here, making it one of the few places in far NorCal where newcomers can safely learn. Even here, cold water requires a thick wetsuit, and shark awareness is essential in the Red Triangle.
