Haʻena State Park
Road's end on the North Shore, and the payoff is Keʻe Beach.
The highway dead-ends at Keʻe Beach, restored taro terraces, and the start of the Napali cliffs. Non-residents need an entry or parking reservation and daily numbers are capped, so book BEFORE you drive out. Snorkel Keʻe on a calm day, then just sit and stare at that ridgeline.
