10 Must-Do Outdoor Activities in Kauai
Between the green rainforests, cascading waterfalls, and sun-soaked beaches, Kauai’s lush landscape is an outdoor enthusiast’s dream. Hawaii’s fourth-largest island is also its most tropical, with an abundance of natural wonders just waiting to be explored. If you're looking for a bit of outdoor adventure, you're guaranteed to find something that sparks your interest in Kauai.
Whale Watching Along the Napali Coast
Get up close and personal with some of Kauai's most majestic residents, the Hawaiian Humpback Whale! From December to April, tens of thousands of these larger-than-life creatures make their way down south from Alaska for the winter. A whale-watching boat tour will allow you to see these gentle giants splashing, playing, and even singing in their natural habitat. Don’t forget to bring your camera, as you might catch them in the middle of a backflip during your tour.
Sunbathe at Hanalei Bay
Snaking two-miles along the northern coast is Hanalei Bay, one of Kauai’s most picturesque beaches. Surrounded by mountainous peaks and swaying palm trees, Hanalei Bay is a prime destination for a relaxing day in the sun. Frolic in the shallow waters, snorkel with schools of tropical creatures, or simply spend the day working on your tan. There are also plenty of luxury resorts, gourmet restaurants, and beachside bars where you can unwind after a day in the sun.
Hike to the Summit of the Sleeping Giant
The Sleeping Giant is arguably one of the most iconic landmarks in all of Kauai. Although it’s officially called Nounou, most people refer to it as the Sleeping Giant, since the shape of the mountain resembles a man lying on his back. Depending on your hiking skill level, there are several different trails to choose from, most of them taking a leisurely 1-2 hours for a roundtrip. We recommend making the trek before sunrise when you’ll be treated to colorful, panoramic views over Kauai’s valleys and shores.
Explore Waterfalls by Helicopter
Kauai is dotted with dozens of breathtaking waterfalls. While some are easy to reach, others are tucked away along the sides of the valleys and canyons, making them more challenging to access. However, a helicopter tour will get you up close and personal with some of the island's most elusive waterfalls, including the jaw-dropping Manawaiopuna Falls in Hanapepe Valley. There’s nothing like having a birds-eye view over one of Mother Nature’s most fascinating natural wonders.
Waimea Canyon State Park, Kauai
Road Trip through Waimea Canyon
Affectionately known as the “Grand Canyon of the Pacific," the massive Waimea Canyon offers a stark contrast to Kauai’s tropical surroundings. The rusted red cliffs and jagged rock formations seem to stretch all the way to the horizon. As you drive through the canyon, you can stop at one of the many different lookout points for sweeping views over the 3,500-foot deep crevices. Puu Hinahina Lookout is the furthest stop but boasts some of the best views in all of Kauai.
Hike Koke’e State Park
Covering a sprawling 4,345 acres, the Koke’e State Park is one of Kauai’s most spectacular gems. It’s a hiker’s dream, with over 45 different hiking trails. Take the intermediate Canyon Trail that leads directly to the impressive 800-foot Waipo’o Falls. Or trek the Alaka’i Swamp Trail for bird-watching along the Kalalau Valley. More experienced hikers can also venture through the Awa‘awapuhi/Nu‘alolo Loop, a steep 10-mile hike with cliff-side valley and ocean views.
Visit the Spouting Horn
If you’re down on the southern coast of Kauai, make sure to stop by the Spouting Horn blowhole. The water from the neighboring Poipu surf channel flows through the underground lava tubes, and the pressure pushes the water from the ground creating the blowhole effect. This gush of water erupts in a loud roar and can reach as high as 50 feet in the air. Legend has it that a giant lizard got stuck in the lava tube after chasing a young boy. Many believe the sound of the eruption is the lizard's growl, while the burst of water from the blowhole is its breath.
Surf the Waves at Poipu Beach
The consistent, barreling waves at Poipu Beach are ideal for surfers of all skill levels. This superb beach has many spots for beginners, including the shallow Lemon Drops and Waiohai. If you’re looking for something a little more exhilarating, you can head west past Poipu Beach for larger waves. PKs, Centers, Heroins, and the infamous Acid Drop surf spots boast long rolling waves that even the most experienced of surfers will find challenging. At these places, try to come during high-tide when the water level is at its safest. Even if you’re not into surfing, you can still participate in a variety of other water sports at Poipu, including snorkeling, bodyboarding, and kitesurfing.
Swim in the Pools of Wailea Falls
Swimming in the sparkling pool of a waterfall is the ultimate bucket list item for any traveler in Kauai. Thankfully, you can live out this dream with a trip to spectacular Wailea Falls. As you make your way down a tree-lined beaten path, you’ll come across an open valley with the powerful, gushing waterfalls in the center. The two cascading streams of Wailea plunge almost 180-feet into a pool of turquoise water, inviting you to come for a swim. If you come early in the morning, you’ll get to see the sunlight hitting the mist from the falls, painting a rainbow in the sky.
Snorkel with Fish at Lawai Beach
The southern coast of Kauai is home to the beautiful Lawai Beach, one of the best destinations for snorkeling. As soon as you set foot in the water, you’ll be surrounded by an abundance of tropical fish and marine life. From friendly Parrot Fish and Snowflake Eels to the colorful Raccoon Rainbow Fish and Clown Fish, there’s an entire world of life to discover underwater. If you’re lucky, you might come across a few Green Turtles and the rare Hawaiian Monk Seal. If you plan on visiting Lawai Beach, make sure to come during low tide when the waters are the calmest.
