History Meets Marine Beauty at Kealakekua Bay
Kealakekua Bay on the Big Island of Hawaiʻi is where history and nature collide. It’s not only the site where British explorer Captain James Cook met his end, but it’s also considered one of Hawaiʻi’s best snorkeling locations, known for crystal-clear waters, vibrant coral reefs, and marine life like dolphins, manta rays and tropical fish.
Whether you’re a history buff or an ocean lover, snorkeling at Kealakekua Bay is an experience you won’t forget.
The Historical Significance: The Death of Captain Cook
Captain James Cook, the British explorer credited with being the first Westerner to chart the Hawaiian Islands, first spotted Oʻahu and Kauaʻi on January 18, 1778. Two days later, he anchored his ship in Waimea Bay off Kauaʻi.
Nearly a year later, on January 17, 1779, Cook arrived at Kealakekua Bay on the Big Island during the Hawaiian Makahiki Festival, a celebration honoring the fertility god Lono. Because of the festival’s religious significance and Cook’s coincidental timing, the Hawaiians initially welcomed him as a god and held a large feast in his honor.
However, when Cook returned unexpectedly a week later after a storm-damaged ship forced him back, the mood shifted. The Hawaiians had realized he was not a deity, and tensions escalated. On February 14, 1779, during a skirmish near Kaʻawaloa Village, Captain Cook and four of his men were killed.
Today, a 27-foot white obelisk — the Captain Cook Monument — stands at the site of his death, erected in 1874 by the British government.
