What should I wear on a Na Pali Coast tour?

Wear your swimsuit or beachwear under your clothes; you’ll be in the water for about an hour at the snorkel stop. Bring sandals or shoes you’re comfortable walking in at the harbor, even if you plan to go barefoot on the boat, because Kikiaola Small Boat Harbor has uneven surfaces near the dock. Leave jewelry, watches, and anything you can’t afford to lose or get wet back at your hotel, since spray comes aboard regularly.
