Things to Do in Kauai: The Ultimate North Shore Activity Guide

Kauai is the smallest of the four main Hawaiian islands, but it packs more adventure per square mile than anywhere else in the Pacific. The Garden Isle is 90% inaccessible by road, which means the best experiences require boats, helicopters, kayaks, hiking boots, or simply the willingness to follow a trail and see where it leads.

After 50 years of living here, I still discover something new every month. Here is everything worth doing on Kauai, organized from the most iconic experiences to the hidden gems most visitors miss.

Must-Do Experiences (The Kauai Bucket List)

See the Na Pali Coast

The Na Pali Coast is Kauai’s crown jewel: 17 miles of 4,000-foot sea cliffs, hanging valleys, waterfalls, and ocean caves accessible only by sea, air, or the Kalalau Trail. There is nothing like it in the world.

You have three options:

• Boat tour: Catamaran or raft tours run along the coast (May-September when oceans are calm). You will see dolphins, sea turtles, and possibly whales in winter. Raft tours get closer to the caves.
• Helicopter tour: The only way to see the interior valleys and Mount Waialeale’s crater. Doors-off tours give better photos. Year-round availability.
• Hike the Kalalau Trail: The 22-mile round trip trail is one of the most famous hikes in the world. Requires permits and overnight camping. The first 2 miles to Hanakapi’ai Beach make for a challenging but rewarding day hike.

Explore Waimea Canyon

Called the “Grand Canyon of the Pacific” by Mark Twain, Waimea Canyon is 14 miles long, 1 mile wide, and 3,600 feet deep. The colors, layered red and green walls against blue sky, are extraordinary. Multiple lookout points and hiking trails let you experience it from rim and canyon floor.

Pro tip: Go early morning for the best light and clearest views. Clouds often move in by afternoon.

Snorkel at Tunnels Beach

Tunnels Beach has one of the best reef systems in Hawaii. In summer, the water is crystal clear, sea turtles cruise past you, and the underwater lava tube formations that give the beach its name create an underwater maze to explore. Bring your own gear and go early for the calmest conditions.

Beach and Water Activities

Surf or Watch Surfing at Hanalei Bay

Hanalei Bay is a surf spot for every level. In summer, gentle waves make it ideal for learning. In winter, massive swells draw expert surfers from around the world. Even if you do not surf, watching the winter waves from the pier is mesmerizing.

Kayak the Wailua River to Secret Falls

The Wailua River is the only navigable river in Hawaii. Paddle upstream through lush jungle, then hike 30 minutes to Uluwehi Falls (Secret Falls), a 100-foot waterfall with a swimming pool at its base. Guided and self-guided kayak rentals available from the river mouth.

Stand-Up Paddleboard on Hanalei Bay or the Hanalei River

SUP is one of the best ways to experience Kauai’s waters. In summer, the calm surface of Hanalei Bay is like glass. From River Estate, you can paddle from the property down the Hanalei River directly to the bay.

Discover Hidden Beaches

Kauai’s secret beaches are the ones that do not appear on tourist maps. They require short hikes, local knowledge, and a willingness to explore. The reward is having a stunning beach to yourself. Our existing guide covers 7 hidden beaches on the North Shore that only locals know about.

Snorkel Year-Round at Anini Beach

When other North Shore beaches are too rough, Anini Beach stays calm behind its protective reef. It is the best spot for families and beginners who want to see tropical fish and sea turtles without battling waves.

Land Adventures

Hike the Kalalau Trail

The best hikes on Kauai include everything from easy botanical garden walks to the legendary 22-mile Kalalau Trail. Even if you are not a serious hiker, the 2-mile hike to Hanakapi’ai Beach is achievable and spectacular. The 4-mile extension to Hanakapi’ai Falls (300 feet tall) is worth every step.

Zip-Line Through the Mountains

Several zip-line operations on Kauai offer courses through valleys and over streams. The longest lines soar over the interior mountains with views that rival the helicopter tours. Most courses accommodate ages 7+ and no experience is needed.

Tube Through Sugar Plantation Tunnels

One of the most unique activities in all of Hawaii: float through old irrigation tunnels built for the sugar plantations over a century ago. In an inner tube, in the dark (headlamp provided), through tunnels carved into the mountainside. It is equal parts relaxing and adventurous. Kids love it.

Visit Limahuli Garden

Limahuli Garden and Preserve is a National Tropical Botanical Garden set in a dramatic valley on the North Shore. The self-guided walk takes you through ancient taro terraces, native plant collections, and one of the most beautiful landscapes on Kauai. Allow 1-2 hours.

ATV Tour in Kipu Ranch

Kipu Ranch is a working cattle ranch on the South Shore that has been used as a filming location for Jurassic Park, Raiders of the Lost Ark, and dozens of other movies. ATV tours take you through the ranch to waterfalls, valleys, and overlooks used in the films.

Cultural Experiences

Attend a Luau

A traditional luau is a must-do on Kauai. The best ones include hula dancing, live Hawaiian music, and a feast with kalua pork cooked in an underground imu. Smith’s Garden Luau on the Wailua River is one of the most authentic on the island.

Visit the Taro Fields of Hanalei

The Hanalei Valley taro fields are one of the most photographed landscapes on Kauai. Taro (kalo) is sacred in Hawaiian culture, and the Hanalei Valley produces most of the poi consumed in Hawaii. Stop at the Hanalei Valley Lookout for the classic view, then sample taro at farm-to-table restaurants in town.

Learn About Hawaiian History

The Kauai Museum in Lihue, Waioli Huiia Church in Hanalei, and the ancient heiau (temples) scattered around the island connect you to the deep history of the Hawaiian people. Cultural experiences on Kauai range from lei-making classes to guided hikes to sacred sites.

Food and Drink

Eat at a Food Truck

Kauai’s food truck scene is the real deal. From the best restaurants in Kauai guide: taro burgers at Hanalei Taro & Juice Co., fresh poke at Kilauea Fish Market, and shave ice that will ruin every snow cone you eat for the rest of your life.

Visit a Farmers Market

The farmers’ markets on Kauai are not tourist attractions; they are where the island feeds itself. Tropical fruits you cannot find on the mainland, just-picked greens, local honey, and fresh-baked bread. Kapaa Sunshine Market (Wednesday) and Hanalei (Saturday) are the best.

Tour a Coffee Farm

Kauai grows some of the best coffee in Hawaii. Several farms on the South and East sides offer tours and tastings. The coffee grown on the Hanalei side has a unique flavor profile from the volcanic soil and mountain rainfall.

Planning Your Kauai Activities

Check the best time to visit Kauai to match your activities to the right season.

Base Your Adventures at River Estate

River Estate sits in the heart of Hanalei, the North Shore’s hub. Most of the activities on this list are within 30 minutes. After a day of hiking, snorkeling, or exploring, you return to a private 2-acre estate with a pool, hot tub, and the sound of the Hanalei River.

Our guests consistently say that the property itself was one of the highlights of their trip, equal parts home base and destination.

The Guest House is ideal for couples. The main River House accommodates families and groups. Both give you the best of where to stay on Kauai.

Getting Around Kauai

Kauai has no public transit system worth relying on, so you will need a rental car. The island is small enough to drive around in about two hours without stops, but the road ends on the North Shore at Ke’e Beach and on the West Side past Polihale. That means no circling the island. Plan your days by region rather than trying to crisscross from coast to coast.

Most visitors fly into Lihue Airport (LIH) on the east side. From there, the North Shore is about 45 minutes north, and Poipu on the South Shore is about 30 minutes south. Booking a rental car well in advance is essential, especially during peak season (December through March and June through August).

Best Free Things to Do in Kauai

Kauai is one of the few Hawaiian islands where the best experiences cost nothing. The beaches are all public. Trailheads are free. Watching the sunset from Hanalei Pier, exploring tide pools at Anini Beach, hiking to waterfalls on the Kalalau Trail’s first two miles, and swimming in the Wailua River are all free. Even the Kilauea Lighthouse lookout is just a few dollars per person.

Farmers markets are another free-to-browse highlight. The Hanalei Saturday market, Kapaa Wednesday market, and Kilauea Thursday market all offer fresh tropical fruit, local honey, and artisan crafts. Budget one hour minimum per visit because the conversations with local vendors are half the experience.

Kauai Rainy Day Activities

Rain on Kauai is normal and usually brief, but some days warrant indoor alternatives. The Kauai Museum in Lihue covers the island’s volcanic and cultural history. Koloa Rum Company and Kauai Beer Company both offer tastings. The Kilauea Fish Market, Postcards Cafe, and Bar Acuda in Hanalei are worth visiting for a long, leisurely meal. And for families, the Kauai Community Players occasionally runs theater productions worth catching.
