Combine sightseeing with relaxation on a boat tour in Kauai. One of the world’s most idyllic destinations, Hawaii’s second-largest island is brimming with diverse natural beauty.

Waterfalls tumble into craters and over sea cliffs. Rugged mountains blanketed in rainforests dominate the island, but arid canyons surprise visitors just a few kilometers away.

Here's all you need to know about boat tours, one of the most invigorating outdoor activities in Kauai.

Snorkeling boat tours

Take in the best of Kaua’s coast from above and below the waves. Booking a snorkeling boat tour is a worry-free way to see Kauai’s rugged shoreline and underwater inhabitants.

Most snorkeling tours focus on the Na Pali coast. The 11-kilometer stretch of shore is rich with history and natural beauty. Although uninhabited now, the Na Pali area’s human history spans centuries, and guides will tell you about the mysterious populations of the past.

The ridges and spires of the sea cliffs reach over 1,000 meters above the waves and are dotted with natural arches and sea caves. Pass by Horn Blowhole to see the spume shoot into the air when waves hit it just right.

Strap on the provided snorkeling gear and dive into clear seas for glimpses of the diverse coral reef ecosystem. See fish and rays, coral gardens and maybe a dolphin.

All of your needs are considered on longer snorkeling boat tours that serve meals and drinks. Some even provide reef-safe sunscreen.

Sunset cruises

Romantic sunset cruises combine sublime scenery and a delectable meal as you and your mate watch the sun slip into the Pacific. Cruise along the Na Pali coast with a drink in your hand for an evening of a lifetime.

Scuba diving trips

If you’re a certified diver, don’t worry about bringing gear on your Hawaiian vacation. You won’t miss out on prime dive spots on a strip that not only lends you diving equipment but also delivers you to some of the best scuba diving in Hawaii.

Wailea river boat trips

Hop on a river boat and motor up the Wailea, the only navigable river in Hawaii. Whether you have a few hours or a full day, you can take advantage of this unique boating experience.

Cruise up the Waimea, the only navigable river in Hawaii. Float under a tropical canopy, alongside waterfalls and end at Fern Grotto, a natural amphitheater perfect for a luau.

Whale watching cruises

In the winter months, Hawaii’s warm waters draw humpback whales to give birth along the islands’ coasts.

With the help of an expert guide, a whale watching tour will lead you to carefully-chosen sites where you’ll have the best chances of seeing pilot whales, rough-toothed dolphins and more.

What can be seen on a boat tour in Kauai?

Na Pali coast

One of the most photographed places in Kauai, the Na Pali coast is replete with stunning images. Cliffs, waterfalls and rock formations will have you reaching for your camera. The 25-kilometer area runs along the northwestern coast of Kauai.

“Pali” means “high cliffs” in Hawaiian, and some tower up to 1,200 meters. The famed “Queen’s Bath” is found within these ridges as well as the Spouting Horn blowhole and countless caves and arches.

Waimea River State Park

You might not think to take a boat tour inland, but a trip on the Waimea River will not disappoint. Make your way to Waimea River State Park as you pass by Olokele Falls, sugar cane fields and sprawling plantations.

The highlight of a Waimea River tour is a stop at Fern Grotto, a place of otherworldly allure. Lava rock walls hung with ferns curve around a basin filled with lush vegetation. The grotto’s walls make a perfect backdrop for luaus that are often held here.

Wildlife

Whales, dolphins, rays and more are waiting for you to discover. Boat trips in Kauai take you over coral reefs that are home to many species of fish and other reef-dwellers.

Keep your eyes peeled for monk seals, manta rays and Hawaiian green sea turtles. Don’t forget to look up. Frigate birds, shearwaters, tropic birds and more find shelter around Kilauea Point.
