The marine life here is abundant because the area is well protected.

A challenging but rewarding 3.5-mile round trip hike down (and back up) a steep trail to the Captain Cook Monument at the edge of Kealakekua Bay. The payoff is some of the best shore-access snorkeling in Hawaii in a marine sanctuary with spinner dolphins, tropical fish, and pristine coral. The hike down through dry scrubland drops about 1400 feet. The climb back up in the heat is the hard part so bring extra water. For families with fit older kids who can handle the physical demands, the snorkeling at the bottom is genuinely world-class.

A unique snorkeling spot where warm water discharged from a nearby power plant attracts an incredible diversity of marine life.

The best viewing is usually in the afternoon.

Boat tours along the leeward coast offer some of the best wild dolphin and sea turtle encounters in Hawaii. Spinner dolphins frequently swim alongside and under the boats in pods of dozens.

Snorkel with giant manta rays at night in one of the most unforgettable wildlife encounters in Hawaii. Operators set up surfboards with lights that attract plankton, which in turn attract manta rays with wingspans up to 12 feet that glide inches below you as they feed.

It sounds scary but the rays have no teeth or stingers and the experience is peaceful and awe-inspiring. This is a bucket-list Hawaii activity.

The whole visit takes 15 to 20 minutes and pairs well with a stop at nearby Allerton Garden.

Natural lava rock tide pools on the coast below the Makapu u Lighthouse Trail that fill with ocean water and create natural swimming holes. The pools range from shallow wading depth to deeper plunge pools. Kids love exploring the marine life in the shallows and swimming in the protected pools.

Sea turtles are regular visitors. The sand is golden and the setting is drop-dead gorgeous.
