🌊 On & in the water
Snorkeling
The signature Hawaii activity. Top spots: Hanauma Bay & Electric Beach (Oʻahu), Molokini & Honolua Bay (Maui), Poʻipū & Tunnels (Kauaʻi), Two Step & Kealakekua (Big Island).
Cost: free from shore; boat tours ~$130–180/person.
Scuba diving
Intro “discover” dives for first-timers; certified diving at Molokini, Kona, and Lānaʻi’s lava tubes.
Cost: ~$150–250 for a 2-tank trip.
Manta ray night snorkel
A Big Island bucket-lister off Kona: lights draw plankton, and giant mantas glide right past you. Magical and beginner-friendly.
Cost: ~$100–160/person.
Boat & sunset cruises
Nā Pali Coast tours (Kauaʻi), Molokini trips (Maui), sunset + dinner sails, whale-free summer wildlife cruises.
Cost: ~$100–300/person depending on length.
Surf & SUP lessons
Waikīkī’s gentle rollers are the world’s most famous learner waves. Stand-up paddle on calm bays everywhere.
Cost: ~$75–150 group lesson.
Just the beach
Sometimes the best plan is a calm cove, a book, and honu (sea turtles) cruising by. Summer = calmer north shores.
Cost: free (give wildlife big space — see rules).
Ocean safety is non-negotiable
Never turn your back on the waves, swim where lifeguards are, and check conditions daily. More on the Things to Know page.
