Dolphins

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. Spinner dolphins, sea turtles, eagle rays, and dense schools of fish are regularly seen in the warm outflow channel. The visibility is good and the marine life density is higher than almost anywhere else on Oahu. The entry is over rocks and there are no lifeguards so this is best for experienced swimmer families. When conditions are calm, the snorkeling is genuinely world-class and free.

A stunning crescent-shaped beach on Lanai south shore that is widely considered one of the best beaches in Hawaii. The marine preserve protects the excellent reef and snorkeling is outstanding with spinner dolphins frequently visiting the bay. Tide pools on the left side of the beach are full of sea life that fascinates kids for hours. The beach has lifeguards, restrooms, and shaded picnic areas. In winter, humpback whales are visible from shore. Getting to Lanai requires a ferry from Maui or a flight, which adds to the adventure.

The site of Maui last volcanic eruption (around 1790) with a dramatic landscape of black lava flows meeting the ocean. The Hoapili Trail crosses the lava field along the coast with views of tide pools, ancient Hawaiian petroglyphs, and distant Molokini crater. Dolphins are frequently spotted in the bay. The terrain is rough and exposed so good shoes and sun protection are essential. Walking on the a-a lava fields is a unique experience that helps kids understand volcanic geology in a tangible way.

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. Several operators also stop at snorkeling reefs where sea turtles are almost guaranteed. The leeward coast is drier and calmer than other parts of Oahu making for comfortable boat conditions. Seeing dolphins leap and spin in the wild is one of those magical moments that stays with kids forever. Choose operators who follow responsible wildlife viewing guidelines.

A boat tour along the most dramatic coastline in Hawaii with 4000-foot sea cliffs, cascading waterfalls, sea caves, and hidden valleys.

Spinner dolphins and sea turtles are frequently spotted. Kids are awestruck by the sheer scale of the cliffs and waterfalls. Choose a catamaran for a smoother ride.
