It is a mesmerizing marine sanctuary and historical site renowned for its crystal-clear waters, vibrant coral reefs, and diverse marine life. A tall white obelisk commemorates the spot where Captain Cook met his bloody end.
The bay offers some of the best snorkelling for families, as well as kayaking, hiking, and boat trips. It is surrounded by striking landscapes and steep cliffs.
Kealakekua Bay captivates visitors with its natural beauty and cultural significance, making it a ‘must-visit’ destination for those seeking a blend of Hawaiian history and stunning scenery.
Best Time To Visit Kealakekua Bay
You should aim to visit Kealakekua Bay in the morning when the water is calm, and the air is cooler.
The morning hours are also when you’re most likely to see pods of spinner dolphins (naiʻa) after their evening hunt and before they rest during the day. Dolphins usually sleep during daylight hours. You must not disturb them during their resting period, typically between 10:00 AM and 2:00 PM.
If you’re planning on snorkelling, marine life is most active in the morning, so those early hours are the best time to spot tropical fish, green sea turtles, and rays!
How To Access Snorkeling At Kealakekua Bay
Kealakekua Bay is situated near Kona on the west coast of Hawaii’s Big Island. While driving directly to the best snorkelling spot is impossible, you can reach it by boat, kayak or on foot. Where you need to go will depend on how you access the Bay.
By Boat: The Pickup point will be confirmed when you book. Boats typically leave from Kailua-Kona or Kahaluu-Keauhou to the north of Kealakekua Bay.
By Kayak: Most kayaks launch from Manini Beach to the south of Kealakekua Bay. Follow Nāpō’opo’o Road (Highway 160) south of the small town of Captain Cook or north of Keokea. Continue until you reach Nāpō’opo’o Beach Park.
By Foot: The trailhead for hiking is just 150m from Highway 11 on Nāpō’opo’o Road, north of Captain Cook town. There is no designated parking, so please park responsibly, as it is a residential area. We managed to park just off the road, adjacent to the trailhead, but you may struggle to find a space if the trail is busy.
Whichever way you choose to access the bay, make sure you take a snorkel and mask!

Kayaking in Hawaii is a great option if you would like to have the freedom to explore the bay under your own power. You’ll find kayak rentals near Manini Beach on Kealakekua Bay from Ehu and Kai.
We recommend taking a guided kayak tour to get the most out of your experience. Your guide will be an expert in the area’s history and will take you to the best locations to spot marine life, including turtles and dolphins.

3 | Kealakekua Bay Hike
The trek, also known as the Captain Cook Monument Trail, is not too arduous, but be aware you may be exposed to full sun. It took us less than an hour each way, stopping fairly frequently to rehydrate, especially on the way back up. As you approach the cliffs, you’ll have stunning panoramic views of the Pacific Ocean and the bay below.
The trail continues toward the iconic Captain Cook Monument, situated on a rocky outcrop, before opening up to the crystal clear waters of Kealakekua Bay.
While rewarding, the trail is moderately challenging, with steep sections and uneven terrain. Wear sturdy footwear, bring plenty of water, and wear protection. We advise setting out early and returning before midday.
Snorkeling At Captain Cook Monument
Kealakekua Bay is one of the best snorkelling destinations in Hawaii. Its calm, warm, crystal-clear sea is home to colourful fish and beautiful corals. We saw several large turtles effortlessly gliding through the water and often had shoals of fish glittering like confetti swimming around us.
The bay is suitable for novice snorkellers, although we always recommend that you be a good swimmer. Never snorkel alone, and if you are in any doubt about your ability, wear a buoyancy aid; these have the added advantage of being highly visible and are a great way to spot your kids!
The sea is relatively shallow, close to the shore, but gets deep quickly as you move further out. The deeper water offers the best chance to see spinner dolphins, although you will see less coral.
Kealakekua is also home to some unique marine life found nowhere else in Hawaii. Snorkelers often spot the exotically named lizardfish, butterflyfish, and angelfish. Our favourite spot was a giant Crown of Thorns starfish, which looked as scary as it sounds!
History Of Captain Cook Monument
The Captain Cook Monument was erected in 1874 in memory of the British Explorer Captain James Cook. The white obelisk stands near the spot where he was killed in 1779 after a dispute with the indigenous Hawaiians turned violent.
The monument serves as a poignant reminder that despite its natural wonder, the bay was once the site of a bloody battle that shaped the histories of Hawaii and Europe.
Is It Worth Snorkeling At Captain Cook Monument?
This has to be a categoric yes! Not only is snorkelling at the Captain Cook Monument worth it, but it is also amongst the best snorkelling in Hawaii. We advise arriving early in the morning when the water is calm and before tour groups arrive.
We started our hike mid-morning, in full sun and heat. While the Bay was not too crowded, there were quite a few tour boats.
Snorkeling Big Island Hawaii
While Kealakekua is undeniably special, there are several other amazing snorkelling areas and unique beaches on Hawaii’s Big Island if you have time to explore.
Honaunau Bay (aka “Two Step Beach”)
Two Step Beach at Homaunau Bay is part of the Pu’uhonua o Honaunau National Historical Park and is a great spot for beginner snorkelers.
A natural lava-rock step (hence the name) leads straight into the ocean, giving easy access to a thriving coral garden where you’ll find many colourful fish. You may also spot turtles in the clear, calm water near shore.
It does get busy here, and we strongly advise taking care walking on the lava as it is sharp.
Kahalu’u Beach Park
This protected cove provides calm and shallow waters and is ideal for practising your snorkelling skills.
You can expect to encounter colourful coral formations, plenty of fish, and perhaps, the occasional sea turtle! This Beach Park is occasionally closed to allow rest time for coral regeneration.
Manta Ray Night Snorkel
If you’ve ever wanted to see one of the most elegant creatures in the ocean, Manta Ray night dives and snorkel experiences may be for you. After dark, you get into the ocean with bright lights attached to a float that attracts plankton. Manta rays, in turn, are attracted to feed on the plankton.
There is a viewing platform outside the Outrigger Resort in Kona, where night snorkelling occurs.
