What places will I visit on a Big Island boat tour?

Kona coast

The beautiful Kona coast stretches around much of the western side of Hawaii. It’s one of the best places for Big Island boat tours thanks to its dramatic scenery and dreamy beaches.

The waters here are calm and clear, which is perfect for snorkeling tours and glass-bottom boat excursions. This is a haven for sea turtles and dolphins so keep a look out during your trip.

Highlights along this part of the Hawaiian coast are Kealakekua Bay and Captain Cook’s Monument.

Captain Cook’s Monument

Kealakekua Bay is where Captain James Cook first came ashore in 1778. The British explorer was the first westerner to set foot on the island and establish contact with the residents of Hawaii. Things didn’t go quite to plan, and he was killed in a skirmish just a year later, here in Kealakekua Bay.

There’s a white obelisk overlooking the bay that stands as a memorial to Captain Cook’s endeavors. It’s located down by the water, so you’ll see it from the deck of your boat as you sail along the shore.

Kealakekua Bay

This sweeping bay on the west coast is one of the most iconic destinations on the entire island. It lies about 20 kilometers south of Kailua Village and is a designated Marine Life Conservation District.

The snorkeling here is sublime, with schools of tropical fish darting about the vivid coral reefs.

A lot of sailing tours on the Big Island feature Kealakekua Bay on their itinerary, thanks to the calm waters and impossibly blue sea. This is where you’ll get your money shot when it comes to vacation photos!

How long do Big Island cruises last?

The duration of boat excursions on the Big Island varies depending on what activities you’re doing along the way.

Snorkeling tours are usually between 3 and 4.5 hours long, giving you enough time to swim and enjoy lunch on board. Shorter 1-hour reef viewing excursions can be enjoyed on the glass-bottom boat.

Dinner cruises are 3 hours long, while sunset sailing trips last 1.5 hours with drinks on board before returning to shore. Whale watching cruises are 2.5 hours, which is plenty of time to see the humpbacks in action.

The private tours are usually half a day, with fishing charters lasting up to 6 hours.

Where do I get the boat?

Most Big Island boat trips set off from either Kailua Kona Pier or Keauhou Bay Pier, over on the west coast. Both are easily reached via the coastal road. Alternatively, you can book a taxi from your hotel.

The sunset sailing tours depart from the Waikoloa Beach Resort in Anaehoomalu Bay up in the northwest of the island. To get here, just take Highway 19 from Kona.

Whale watching cruises set off from Honokohau Harbor, just south of Kona airport. You can reach the marina via Highway 19.

Parking is available at all the locations if you’ve come by car.

When is the best time for a boat trip on the Big Island?

The ocean is at its calmest in spring and summer, so this is the ultimate time for boat cruises on the Big Island. For the warmer weather, visit between March and September – this is the dry season which is perfect for boating.

There are both morning and afternoon tours on offer, so just take your pick of the time slots. For something extra special, head out in the evening on a dinner cruise or a sunset sailing trip.
