Historic bay, snorkeling & monuments.
Directions Maps, and Info
Overview
Kealakekua Bay is one of the most historically and culturally significant sites in Hawaii. This deep, sheltered bay was the landing site of Captain James Cook in 1779, marking the first extensive contact between Hawaiians and Western explorers. It was also where Cook met his fate, adding to the site’s complex history.
Beyond its historical importance, Kealakekua Bay is famous for crystal-clear waters, vibrant coral reefs, and incredible snorkeling. The bay is a Marine Life Conservation District, making it one of the best places on the Big Island to see tropical fish, dolphins, and even the occasional reef shark.

If you plan to kayak or snorkel near the Captain Cook Monument, you must either hike in, kayak with a permitted operator, or book a guided boat tour. Private kayaking is only allowed with a permit, and land access to the monument requires a strenuous 3.8-mile round-trip hike.

What to Bring
Snorkel gear – The reef is teeming with marine life, but no rentals are available on-site.
Reef-safe sunscreen – Help protect the delicate coral ecosystem.
Plenty of water – The area gets hot, and if you’re hiking, there are no facilities along the trail.
Hiking shoes – If you plan to trek to the Captain Cook Monument, wear sturdy shoes for the rough trail.
Dry bag – Essential for keeping valuables safe if kayaking or boating.
What to Expect
World-Class Snorkeling
The waters near the Captain Cook Monument are some of the clearest in Hawaii, with an abundance of tropical fish and coral. Due to its protected status, marine life thrives here, making it one of the top snorkeling spots on the island.
Dolphin Sightings
Kealakekua Bay is home to Hawaiian spinner dolphins, which sometimes rest in the bay during the day. While they are beautiful to watch, swimming with them is discouraged to avoid disturbing their natural behavior.
Captain Cook Monument
A towering white obelisk marks the site where Captain James Cook was killed in 1779. The area is only accessible by boat, kayak, or a steep hike, making it one of the more remote and serene historical landmarks in Hawaii.
Challenging Hike
The Ka‘awaloa Trail leads to the Captain Cook Monument but is not for the faint of heart. The 1.9-mile hike down is manageable, but the return trip is strenuous with little shade. Bring extra water and be prepared for a tough ascent.
Tips & Info
Book a guided tour for easy access
If you don’t want to hike or get a kayak permit, booking a snorkeling or boat tour is the best way to experience the bay.
Arrive early to avoid crowds
Mornings offer the best conditions for snorkeling and kayaking, and parking is limited.
Respect the marine life
Do not touch the coral or attempt to swim with dolphins. Keep a safe distance to preserve the ecosystem.
Bring more water than you think you’ll need
The hike is exposed to full sun, and dehydration is a real concern.
Check permit rules before kayaking
Independent kayak access is restricted and requires a DLNR permit. Guided kayak tours are available if you don’t have one.

Kealakekua Bay State Historical Park offers an incredible mix of history, culture, and world-class snorkeling. Whether you visit for the stunning marine life, the challenging hike to the Captain Cook Monument, or to take in the rich Hawaiian history, this bay is a must-see destination on the Big Island.
