The Best Things to Do in Kauai
The Garden Isle's Best Adventures
Kauai is the oldest of the main Hawaiian islands, and time has carved it into something the younger islands can't match. Much of the coastline and interior is inaccessible by road. The roughly 16-mile Na Pali Coast drops 4,000-foot fluted cliffs straight into the Pacific. Waimea Canyon cuts deep into the west side of the island. Mt. Waialeale averages 450 inches of rain per year, feeding waterfalls that pour down every ridge. This is Hawaii at its most raw.
The roughly 552-square-mile island stays quieter than Oahu or Maui by design. No building stands taller than a coconut palm. Most tours launch from three hubs: Poipu on the sunny south shore, Port Allen harbor on the west side (Na Pali boat tours), and Wailua on the east (river kayaking, waterfall hikes). Helicopter tours typically depart from Lihue airport. Book Na Pali boat tours and helicopter flights at least 2-3 weeks ahead during busy holiday and summer travel windows because operators run smaller boats and fewer aircraft than the bigger islands.
Below you'll find our tested picks across every category, from Na Pali catamaran cruises and Wailua River kayak trips to mountain tubing through old sugar plantation irrigation tunnels. Check live operator rates before booking, especially during holiday and summer travel windows.
We've been coming to Kauai since our early Hawaiʻi trips, and the Garden Isle rewards slowing down more than any other island. Out of everything here, these are the days we'd tell a friend not to miss — the coast, the canyon, the rivers, and the one cultural night everyone should do.

Bucket list
1 Cruise the Nā Pali Coast
Kauai's signature coastline — miles of fluted emerald cliffs dropping straight into the sea, with no road and no way in except by boat, kayak, or air. A catamaran or raft tour along it is the single most-Kauai thing you can do. Summer is calmest for the north-shore departures.
-
Big views
2 Take in Waimea Canyon
Nicknamed the “Grand Canyon of the Pacific,” and the name undersells the color — red, ochre, and green folding away for some fourteen miles. The lookouts right off the highway do most of the work; go in the morning before the clouds settle into the canyon.
-
Splurge
3 See it by helicopter
More of Kauai is roadless than not — the Nā Pali cliffs, the Waimea gorges, the streaming walls of Mount Waiʻaleʻale — and a helicopter is the only way to see most of it. It's the splurge people come home talking about.
-
Beach day
4 Settle in at Hanalei Bay
A two-mile crescent of sand on the north shore, backed by green mountains streaked with waterfalls. Calm and swimmable in summer, big and surf-y in winter. The old pier at the east end is the postcard everyone takes.
-
For hikers
5 Hike toward Kalalau
The Kalalau Trail along the Nā Pali Coast is one of the great hikes on earth. Even the first two miles to Hanakāpīʻai Beach are a workout with a payoff; the full 11 miles into Kalalau Valley is a serious, permitted backcountry trek. Check trail status and conditions before you go.
-
Roadside stop
6 Pull over for Wailua Falls
A double waterfall you can see from a roadside pullout a few minutes off the highway near Līhuʻe — the easiest big-payoff stop on the island. The viewpoint is the safe way to see it; the unofficial trail down is steep and slick.
-
First-timers
7 Have a beach day at Poʻipū
Kauai's sunny south-shore beach — golden sand, easy swimming, a protected keiki pool, and Hawaiian monk seals that haul out to nap on the sand. Give the seals a wide berth; it's the law and the right thing.
-
Snorkelers
8 Snorkel the north-shore reefs
The reefs at Tunnels and Keʻe are some of the best snorkeling on Kauai in calm summer water — and genuinely dangerous when the winter surf is up. Go in the morning, check conditions, and never turn your back on the ocean here.
-
Evening out
9 Spend a night at a luau
If you do one cultural evening on Kauai, make it a luau — the imu-roasted food, the hula, and the story of the islands in one sitting. Book ahead; the good ones fill up in peak season.
-
Quick stop
10 Watch the Spouting Horn
On the south shore near Poʻipū, surf forces up through a lava tube and blasts a geyser of seawater into the air, with a moan the old stories tie to a trapped moʻo. A quick, free stop with a real wow.
-
Active
11 Kayak the Wailua River
The Wailua is one of the only navigable rivers in Hawaiʻi, winding past sacred sites to the trailhead for Uluwehi (Secret) Falls. A guided paddle-and-hike is a half-day done right — and the river's heiau make it worth going with someone who'll tell the history.
-
By boat
12 Drift up to Fern Grotto
A fern-draped lava grotto up the Wailua River, reachable only by boat. It's touristy and it's also genuinely lovely — a short riverboat ride with music and a green amphitheater of ferns at the end.
-
Wildlife
13 Visit Kīlauea Lighthouse
The 1913 lighthouse on Kauai's northern tip sits on a cliff that doubles as a national wildlife refuge — nēnē, red-footed boobies, frigatebirds, and often spinner dolphins or whales offshore. Bring binoculars and a little patience.
Hidden Gems & Local Favorites on Kauaʻi
The 13 above are the names everyone arrives knowing. These are the stops that reward the travelers who keep driving to the end of the road — the west-end beach with no lifeguard, the art town that only wakes up on Fridays, the coast that still has no resorts on it. Most are simple to fold into a day plan, and all of them are why people come back.
Polihale State Park
Drive past Kekaha until the highway runs out and a few miles of cane road take over, and you reach the westernmost beach on Kauaʻi — one of the longest unbroken stretches of sand in the state, backed by dunes and capped at its north end by the start of the Nā Pali cliffs. The sunsets out here are the whole point. The shore break is heavy and there are no lifeguards, so this is a beach for walking and watching, not swimming, and the access road wants a high-clearance vehicle.
Hanapepe & Friday Art Night
The west-side town that bills itself as “Kauaʻi’s biggest little town” spends six days a week quiet and then lights up on Friday evenings, when the galleries stay open, food trucks pull in, and music spills onto the street. The old plantation storefronts and the swinging footbridge over the river make it worth a slow walk any day of the week.
Old Kōloa Town
Hawaiʻi’s first commercially successful sugar plantation took root here in 1835, and the old town that grew up around it is now a string of monkeypod-shaded storefronts turned into shops and small eateries. It’s the natural pause on the way down to Poʻipū — a little history, a little shade, and shave ice within easy reach.
Sleeping Giant (Nounou) Trail
From the highway near Wailua, the east-side ridge really does look like a giant lying on his back. The trail up his flank is a moderate climb that most reasonably-fit travelers can manage, and the payoff is a wide view back over the coast and into Kauaʻi’s green interior. A good half-day hike that doesn’t require driving to the far side of the island.
Kauaʻi Bike Path (Ke Ala Hele Makalae)
A paved, mostly flat coastal path runs along the east shore through Kapaʻa, with the ocean on one side nearly the whole way. Rent a cruiser in town and you’ve got an easy, kid-friendly morning with beach access, coffee stops, and — in winter — a decent chance of spotting whales from the path itself.
Queen’s Bath
A tide pool carved into the lava bench below Princeville, reached by a short, muddy scramble down to the shore. In flat summer surf it can be a calm soak with the ocean crashing just past the rim. In winter it is genuinely deadly — people have been swept off these rocks and drowned. Check the surf report, never go when the north swell is up, and if the waves are reaching the ledge, turn around.
Māhāʻulepū & the Makawehi Cliffs
Just east of the Poʻipū resorts, the pavement ends and the coast turns wild — one of the last stretches of south-shore shoreline with nothing built on it. A heritage trail runs along the fossilized sand-dune cliffs at Makawehi past sea caves, blowholes, and a sinkhole full of ancient pollen. Windy, undeveloped, and completely different from the manicured beaches a mile back.

Our Top Kauai Activities
Kauai Activities & Adventures
Kauai packs more scenic density per square mile than any island in the chain. The payoff: world-class adventures that feel half a world away from the resort pool. Here are the experiences worth building your trip around.
Na Pali Coast Boat Tours
Roughly 16 miles of fluted emerald cliffs, sea caves, and hanging valleys lie beyond the road network. The coast can be seen by boat or helicopter, while the Kalalau Trail provides the demanding overland route. Most visitors choose the boat. Catamaran cruises from Port Allen run 4-5 hours and typically include snorkeling at Nu'alolo Kai (conditions permitting), lunch, and drinks. Zodiac raft tours are faster, wetter, and get closer to the cliff face and sea caves. Morning departures usually have calmer seas. The Na Pali Coast is accessible by boat roughly May through September on the north/west side; winter swells shut down most operations from October through April, when sunset cruises along the south shore become the alternative.
Combine a morning boat tour with a sunset cocktail cruise on a different day for two completely different perspectives of the same coastline. Browse all Na Pali boat tours →
Helicopter Tours
Kauai is the one island where a helicopter tour isn't a luxury splurge but a near-necessity. Much of the island is inaccessible by road, and the interior is a maze of razor-thin ridges, 3,000-foot waterfalls, and cloud-wrapped valleys that you will never see from the ground. Standard flights run 50-65 minutes from Lihue airport, with pricing varying by operator, aircraft, seating, and doors-off options. Doors-off flights usually cost more but deliver better photos. The route typically covers Waimea Canyon, the Na Pali Coast, Mt. Waialeale's crater wall (where waterfalls pour from every crevice after rain), and Manawaiopuna Falls, the waterfall from Jurassic Park.
Morning flights tend to have clearer skies. Book 2-3 weeks ahead during busier travel windows. Weight policies are strict and vary by operator, aircraft, and party size, and cancellations due to weather are common in winter. Compare Kauai helicopter tours →
Beyond helicopters, Kauai also has small-plane flightseeing, tandem skydiving over the North Shore, and other air experiences. See all Kauai air adventures →
Hiking & Trails
Kauai has 17 major trail systems across terrain that ranges from coastal cliff walks to bog-swamp ridgelines at 4,000 feet. The Kalalau Trail is the headliner: 11 miles one-way along the Na Pali Coast to Kalalau Beach, one of Hawaii's most remote stretches of sand. The first 2 miles to Hanakapi'ai Beach are doable as a day hike; the full trail requires a camping permit and real backcountry fitness. Hāʻena State Park entry, shuttle, and parking reservations are handled through gohaena.com; non-resident fees vary by entry, parking, and shuttle selection.
For something less committing, the Sleeping Giant (Nounou Mountain) trail climbs 1,000 feet in 2 miles to panoramic east-side views. The Awa'awapuhi Trail in Koke'e descends 1,600 feet to a jaw-dropping Na Pali lookout. And the Pihea Trail connects to the Alaka'i Swamp Trail, a boardwalk through one of the highest-elevation bogs on Earth. See all Kauai hiking trails →
Waimea Canyon & Koke'e
It's nicknamed the "Grand Canyon of the Pacific," and from the main lookout at 3,400 feet you'll understand why. Waimea Canyon is layered in reds and greens that shift with the light. Non-residents pay separate entry and parking fees for Waimea Canyon State Park. The same receipt covers Koke'e State Park further up the road, where trails branch into rainforest, the Kalalau Lookout stares down 4,000 feet to the Na Pali Coast, and the small Koke'e Museum offers free maps of the trail network.
Drive up early. Clouds typically roll in by mid-morning and obscure the canyon views by afternoon. The road from Waimea town climbs 3,500 feet in 15 miles with plenty of pulloffs. Pack a layer; temperatures at the top run 10-15 degrees cooler than the coast.
Kayaking & Wailua River
The Wailua River is the only navigable river in Hawaii, and paddling it to Uluwehi Falls (Secret Falls) is one of Kauai's signature half-day adventures. Guided kayak tours take about 5 hours round-trip and include the 2-mile paddle upstream plus a 1-mile jungle hike to a waterfall pool. The paddle is easy enough for beginners and many families, but check the live operator age rules before promising it to a child. Self-guided rentals are available if you want to go at your own pace.
Na Pali Coast sea kayaking is a different beast entirely: a 17-mile open-ocean paddle past sea caves and waterfalls, available only in summer (May-September) when north shore swells die down. It's a full-day expedition with operator-specific pricing and real paddling-fitness requirements. Browse Kauai kayaking tours →
Snorkeling
Poipu Beach is the easiest entry point: a protected crescent on the sunny south shore where green sea turtles and Hawaiian monk seals are regular visitors. Anini Beach on the north shore has a 2-mile reef that keeps the water calm and shallow, ideal for families. Tunnels Beach (Makua) offers more advanced reef snorkeling with bigger fish and occasional reef sharks, but check swell reports first because winter waves shut it down.
Boat snorkel tours reach reefs and coastline you can't access from shore, including spots along the Na Pali Coast in summer. Most south-shore catamaran tours include gear, lunch, and 2-3 snorkel stops. Check live operator pricing because south-shore and Na Pali trips can differ sharply. Compare Kauai snorkeling tours →
Whale Watching
North Pacific humpback whales migrate to Hawaiian waters every winter, and Kauai's smaller tour boats often get closer encounters than the larger vessels on Maui. Season generally runs November through April, peaking January through March when humpback activity is typically strongest in Hawaiian waters. Tours depart from Port Allen and Poipu and usually run 2-3 hours. Many operators guarantee a sighting or offer a free rebooking.
You can also spot whales from shore at Poipu Beach and the Kilauea Lighthouse overlook on the north shore. Binoculars help. Browse whale watching tours →
Luaus
Kauai's luaus tend to feel more intimate than the 500-seat productions on Maui or Oahu. Adult ticket prices vary by seating tier, drink package, and venue. Most include a full Hawaiian buffet (kalua pig, poi, poke, haupia), live music, hula, and a fire-knife finale. The south shore and east side host most venues, with sunset ocean views at the premium spots.
Book at least a week ahead, especially for Friday and Saturday shows in peak season. Some venues offer premium seating with better sightlines or upgraded bar access. Compare Kauai luaus →
Surfing & Stand-Up Paddleboarding
Poipu Beach and Hanalei Bay are Kauai's two main learn-to-surf zones. Poipu Surf School and nearby operators run paid lessons on the south shore's gentle, consistent breaks; check current lesson length, group size, and total price before booking. Hanalei Bay on the north shore has a wider range of waves, from beginner-friendly inside breaks to the more powerful reef breaks at the pier that intermediate surfers enjoy in summer.
Stand-up paddleboarding works best on the Wailua River (flat water, no waves to fight) or inside the reef at Anini Beach. Rental rates vary by board type, shop, and rental length in Poipu and Kapa'a. Winter north shore surf gets serious (15-25 foot faces), strictly for experts who know the reefs.
Mountain Tubing
This is a Kauai-only experience. You float through hand-dug irrigation tunnels built for the old Lihue Sugar Plantation system circa 1870. The tunnels are dark enough that you wear a headlamp, the water is mountain-fed and cool, and the open ditch sections run through rainforest with mountain views. The tour takes 3 hours total, and guests must be at least 5 years old, 43 inches tall, and 300 pounds or less. Only one operator runs this route, so confirm the live rate and book early in your trip in case weather or availability forces a reschedule. Book mountain tubing →
Zipline & ATV Adventures
Kauai's zipline courses string across valleys and former plantation land, with lines reaching 1/2 mile long and heights over 200 feet. Multi-line courses typically take 3-4 hours. ATV tours cover backcountry terrain on the south and west sides of the island, including valleys used as filming locations for Jurassic Park, Raiders of the Lost Ark, and South Pacific. Check live pricing before booking because vehicle type, route length, and passenger rules vary by operator. Weight and age minimums vary by operator.
Both activities run rain or shine. Kauai gets wet, and honestly, the mud makes it more fun. Wear clothes you don't mind getting dirty.
Horseback Riding
Kauai's horseback rides split cleanly by activity style. South shore riders usually look toward Koloa and Maha'ulepu for ocean-view ranch scenery, while Princeville works better for riding lessons than long trail tours. Age limits, weight limits, and ride style vary enough that this is worth checking before you promise the activity to a child or first-time rider. Compare Kauai horseback riding options →
Garden Tours
Kauai's "Garden Isle" nickname comes from real credentials. Limahuli Garden & Preserve on the north shore sits in a valley backed by 2,000-foot cliffs and preserves native Hawaiian plants and ancient taro terraces. Non-resident self-guided access is a paid timed-entry visit, while guided tours are a higher-tier option with limited weekly availability. The National Tropical Botanical Garden (Allerton & McBryde) near Poipu features the famous Moreton Bay fig trees from Jurassic Park. Current NTBG guided garden options vary by route and should be checked before booking. Na 'Aina Kai on the north shore combines botanical gardens with bronze sculpture and a hedge maze.
Garden tours are the best rainy-day backup plan on Kauai. Everything looks better wet. Browse garden tours →
Coffee Farm Tours
The largest coffee farm in the United States is on Kauai, not the Big Island. Kauai Coffee Company in Kalaheo covers 3,100 acres with roughly 4 million trees, offers free tastings, and has a self-guided walking route for visitors. Guided walking and open-air-truck farm tours build on top of that, with current schedules and prices handled by the farm. On the North Shore, Moloa'a Bay Coffee runs a 4,000-tree family operation that hosts visitors by appointment.
Pair the coffee morning with the NTBG garden tours next door and Poipu beaches in the afternoon. Visit Kauai coffee country →
Golf Courses
Kauai golf splits by region. East-side visitors get the best value at Wailua Municipal, Poipu guests have the simplest access to Poipu Bay, North Shore visitors look toward Princeville Makai, and Lihue-area stays pair naturally with Hokuala. Choose by where you are staying before chasing a famous course name across the island. Compare Kauai golf courses →
Sunset & Dinner Cruises
Kauai's west-facing coastline delivers some of the best sunsets in Hawaii. Sunset catamaran cruises from Port Allen and Poipu usually run 2-3 hours, with inclusions such as dinner, open bar, or live music varying by vessel. The south shore runs year-round; Na Pali sunset sails operate in summer only (May-September) and are worth the premium for the golden-hour light on those cliffs.
Smaller sailboats offer a quieter, more romantic alternative to the larger catamarans. Browse sunset cruises →

Frequently Asked Questions
What are the best things to do on Kauaʻi?
The top things to do on Kauaʻi include a Nā Pali Coast boat tour or helicopter flight, hiking Waimea Canyon, snorkeling at Poʻipū Beach, kayaking the Wailua River to Secret Falls, visiting Wailua Falls, and exploring Hanalei Bay on the North Shore.
How many days do you need on Kauaʻi?
Most visitors need 5 to 7 days to experience Kauaʻi without rushing. You can see the highlights in 3 to 4 days, but a full week lets you hike deeper into Kōkeʻe State Park, explore multiple beaches, and take both a helicopter tour and a Nā Pali boat trip. See our itineraries for day-by-day plans.
Is Kauaʻi better than Maui?
Kauaʻi is better for nature lovers, hikers, and travelers seeking a quieter, less developed island. Maui has more resort infrastructure, restaurants, and nightlife. Kauaʻi has more dramatic scenery — the Nā Pali Coast and Waimea Canyon are unlike anything on Maui. Not sure? Try our Which Island quiz.
What should you not miss on Kauaʻi?
Do not miss the Nā Pali Coast (by boat, helicopter, or trail), Waimea Canyon, Poʻipū Beach, a helicopter tour of the island interior, and Hanalei Bay. Wailua Falls and the Kalalau Lookout are also essential stops.
Is Kauaʻi good for families?
Kauaʻi is excellent for families. Poʻipū Beach has calm, lifeguard-protected water and monk seal sightings. The Wailua River kayak trip is kid-friendly, Waimea Canyon has accessible lookouts, and the overall pace of the island is relaxed and manageable with children.
