Where is Kealakekua Bay located?

You’ll find Kealakekua Bay on the west coast of Big Island, just 19 kilometers south of Kailua-Kona. It’s easy to get to Kealakekua Bay from anywhere in Hawaii. You can visit on a guided tour or travel independently if you have a rental vehicle.

If you want to visit the Captain Cook Monument on foot, note that the obelisk lies in the Kealakekua Bay State Park. There is no road access to this side of the cove. Therefore, you’ll need to walk along the Monument Trail from Napoopoo Road.

Visits to Kealakekua Bay are usually enjoyed with a boat tour, so you can explore areas that are not always accessible by land. Here’s what you’ll get to do during your trip:

Snorkel over the reefs

Snorkeling is the most coveted of activities in Kealakekua Bay. This water here is so clear you can spot fish from the boat, but nothing beats swimming alongside the local marine inhabitants.

The reefs here are renowned for their diversity, and the colors are incredible to behold. Many boat operators have floatation devices so that even non-swimmers can enjoy the underwater show.

Wildlife spotting

Hawaii is famous for its wildlife, but nowhere is it as prevalent as here on the Kona coast. As you cruise along to Kealakekua Bay, keep your eyes peeled for dolphins and turtles who like to feed and play in the area.

During the winter months, humpback whales are regularly sighted. They’ve come all the way from Alaska to breed in warmer waters. If you’re lucky you might even see a calf.

See the Captain Cook Monument

On boat trips to Kealakekua Bay, you’ll cruise by the Captain Cook Monument, which is down on the shoreline. This is where the British explorer landed when he visited Hawaii in 1778. It’s also where he was killed later during his expedition during a skirmish with the locals.

Today the white obelisk serves as a memorial to the captain and is an integral part of any visit to Kealakekua Bay.
