San Onofre (Old Man's) is one of the most famous longboarding waves in the world — a mellow cobblestone point break that rolls 200-400 yards offshore, perfect for learning and cruising. The vibe is inclusive and family-friendly: geezers rule, grommets learn. The decommissioned nuclear plant next door (shut down since 2013) adds a surreal backdrop, though spent fuel is still stored on-site.
