North Shore
The surf capital of the world — waves reach 15–30 feet at Pipeline and Sunset Beach November through February. April through September the swell drops and beginners can take lessons at Waimea Bay or in Haleiwa town. Best day structure: start in Haleiwa for breakfast (Waialua Bakery or Sunrise Shack), drive east along Kamehameha Hwy stopping at Laniakea turtles, Waimea Bay and Valley, Ehukai Pillbox if the group wants a hike, then Pipeline and Sunset Beach. Finish with Giovanni's shrimp truck (garlic butter; cash only). Go on a weekday — Saturday traffic through Haleiwa creates genuine 2-hour gridlock.
No booking for beach access. Surf lessons: Surf-N-Sea shop in Haleiwa or Hans Hedemann Surf School. Shrimp trucks and Matsumoto's Shave Ice prefer cash.
Nov–Feb: dangerous for non-surfers regardless of how benign it looks. Red flag = no water entry, ever.
