Things to Do in Kauai: the Na Pali Coast, Waimea Canyon, and Hanalei Bay

Kauai is the oldest and greenest of the main Hawaiian islands, a place where erosion has had the most time to work and the scenery shows it. The headliners are the fluted cliffs of the Na Pali Coast on the northwest, which no road reaches, and Waimea Canyon on the west, a mile after mile gorge that Mark Twain is said to have called the Grand Canyon of the Pacific. Add the beaches and taro fields of Hanalei on the north shore and the sunny coves of Poipu on the south. Plan around long drives, the weather, and reservations for the busiest parks.

Best fit

Travelers who want dramatic, green scenery over nightlife: sea cliffs and a deep canyon, waterfalls and taro valleys, and calm and wild beaches, all on an island that stays rural and rainy enough to earn the Garden Isle name.

Start here

See the Na Pali Coast by boat or helicopter, drive up Waimea Canyon to the lookouts, and split beach time between Hanalei on the north shore and Poipu on the south.

Do not assume

No road circles the island, so drives are long, the north shore is much wetter, and Haena State Park at the start of the Kalalau Trail requires advance reservations to enter and park.

Decision system

The planning sequence

Use the sequence below to decide how this should shape the trip.

SightWhat anchors itPlanning note

Na Pali CoastRoughly seventeen miles of fluted cliffs with no through roadSee it by catamaran or raft tour from the west or, in summer, from Hanalei, by helicopter, or on foot along the Kalalau Trail.

Waimea Canyon and KokeeA gorge up to about 3,000 feet deep, the Grand Canyon of the PacificDrive Waimea Canyon Drive to the main lookout and on to Kokee State Park and the Kalalau Lookout over the Na Pali cliffs.

Hanalei Bay and the north shoreA crescent bay, a historic pier, and taro fields under green peaksThe classic north shore base; beautiful and wet, with the best swimming in summer and big surf in winter.

Wailua River and waterfallsThe state's navigable river, with the Fern Grotto and roadside fallsReach the Fern Grotto by boat, and pull off for Opaekaa Falls and the twin drop of Wailua Falls nearby.

Poipu and the south shoreSunny beaches, the Spouting Horn blowhole, and frequent monk sealsThe reliably dry, family friendly side; Poipu Beach Park is a top swim spot and Old Koloa Town sits just inland.

Haena State Park and Kee BeachThe northwest road end, trailhead for the Kalalau TrailEntry and parking require advance reservations, or take the shuttle; the first two miles of the trail reach Hanakapiai Beach.

1Day one: See the Na Pali Coast, either on a morning catamaran or raft tour along the cliffs or on a helicopter flight over the whole island interior.

2Day two: Drive up Waimea Canyon Drive to the Waimea Canyon Lookout, continue to Kokee State Park, and finish at the Kalalau Lookout when it is clear.

3Day three: Explore the north shore around Hanalei Bay, its pier and taro fields, and reserve ahead to reach Haena State Park and Kee Beach.

4Day four: Take the south shore at Poipu, swimming at Poipu Beach Park, watching the Spouting Horn, and browsing Old Koloa Town inland.

5Any day: Chase the Wailua River waterfalls, riding a boat to the Fern Grotto and pulling off for Opaekaa Falls and Wailua Falls.

Why the island shapes the trip

An old island carved by water

Kauai rewards a little geography. As the oldest main island it has been eroding the longest, which is why the interior is a maze of gorges and waterfalls and the coast rises in the sheer green pleats of the Na Pali cliffs. Those cliffs are the reason no road circles the island: the belt highway runs out at Haena in the north and at Polihale in the west, and the wilderness between is reached only by boat, air, or the Kalalau Trail. Rain feeds all that green, heaviest on the north shore, so the weather and the long drives shape almost every day here.

See the Na Pali Coast by boat or air

The Na Pali Coast is the reason many people come to Kauai, a wall of fluted green cliffs on the northwest that no road can reach. The three ways to see it each have a season and a mood. Boat tours, on catamarans or faster rafts, run mostly from the west side at Port Allen year round and from Hanalei in the calmer summer, often with snorkeling and sea caves. Helicopter flights add the island's waterfall-laced interior in one loop. The third way is on foot, hiking in along the Kalalau Trail from the north shore, described below.

Drive Waimea Canyon and Kokee State Park

On the dry west side, Waimea Canyon cuts about ten miles long and up to three thousand feet deep, its walls banded red, orange, and green, and it earns the nickname Grand Canyon of the Pacific. Waimea Canyon Drive climbs past a string of lookouts, the main Waimea Canyon Lookout being the easiest big view. Keep going and the road enters Kokee State Park and ends at the Kalalau Lookout, which peers down the Na Pali cliffs to the sea when the clouds lift. Go in the morning for the clearest air, bring a layer for the elevation, and fuel up before you climb.

Settle into Hanalei and the north shore

The north shore around Hanalei is the lush, postcard Kauai, a wide crescent bay backed by green ridges and laced with waterfalls after rain. Hanalei town keeps its old plantation feel, the historic pier draws swimmers and anglers, and taro fields fill the river valley just inland. Summer brings the calmest water and best swimming; winter sends big surf that suits watching more than wading. This side is also the wettest part of the island, so expect passing showers, pack for them, and treat a rainbow over the bay as the standard rather than the exception.

Reserve Haena State Park and hike the Kalalau Trail

At the very end of the north shore road, Haena State Park holds Kee Beach and the trailhead for the famous Kalalau Trail into the Na Pali wilderness. To protect the area, the park now requires advance reservations for entry and parking, or you can ride the north shore shuttle instead, so book well ahead in peak season. Most visitors hike only the first two miles to Hanakapiai Beach, a steep, muddy, and rewarding stretch; going beyond to the falls or deeper into Kalalau demands more time, fitness, and permits. Never cross the Hanakapiai stream in high water.

Take the south shore at Poipu and the Wailua falls

For reliable sun, aim south to Poipu, the driest and most swimmable coast on the island. Poipu Beach Park is a family favorite, Hawaiian monk seals sometimes haul out on the sand, and the nearby Spouting Horn blowhole shoots seawater through a lava tube. Old Koloa Town sits just inland with shops and history. On the east side, the Wailua River is the state's only navigable river, with boat trips to the Fern Grotto and easy roadside stops at Opaekaa Falls and the twin cascade of Wailua Falls. Together they make an easy day when the north shore is socked in.

Planning traps

Mistakes to avoid

These are the small decisions that quietly derail an otherwise good plan.

1. Trying to drive around the island

No road circles Kauai, since the Na Pali cliffs block the northwest, so plans that assume a loop fall apart. The highway dead ends at Haena in the north and Polihale in the west, and getting between the north and south shores means backtracking, so cluster each day by region.

2. Ignoring Haena reservations

Haena State Park, home to Kee Beach and the Kalalau trailhead, caps visitors and requires advance reservations for entry and parking, which sell out in peak season. Book ahead or plan to take the shuttle, or you may be turned away at the gate.

3. Underestimating the north shore rain

The north shore is one of the wettest places around, and a downpour can wash out beach plans in an hour. Keep the sunny south shore and Waimea Canyon as flexible backups, and do not judge Kauai by a single gray morning in Hanalei.

4. Taking the ocean lightly

Kauai's surf and currents turn dangerous fast, especially on unguarded north shore beaches in winter and at stream crossings on the Kalalau Trail. Swim where lifeguards are posted, heed the warning signs, and never cross the Hanakapiai stream when it is running high.

FAQ

Common planning questions

What is Kauai known for?

Kauai, the Garden Isle, is known for the fluted sea cliffs of the Na Pali Coast, the deep gorge of Waimea Canyon, the beaches and taro fields around Hanalei Bay, the sunny south shore at Poipu, and the waterfalls of the Wailua River, all wrapped in the lush green of the oldest main Hawaiian island.

How many days do you need in Kauai?

Four to five days let you see the Na Pali Coast by boat or air, drive Waimea Canyon, and enjoy both the north shore at Hanalei and the south shore at Poipu without rushing. A week gives room for the Kalalau Trail, more beaches, and weather days, which Kauai's rain makes wise.

Do you need reservations for Haena State Park?

Yes. Haena State Park, which holds Kee Beach and the Kalalau trailhead, requires advance reservations for entry and parking to limit crowds, and slots sell out in busy months. You can reserve online ahead of time or use the north shore shuttle, but you cannot count on driving up and getting in.

When is the best time to visit Kauai?

Kauai is a year round destination, but summer brings the calmest north shore water and the best Na Pali boat access, while winter delivers big surf and more rain up north. Spring and fall are quieter and often drier, and the south shore at Poipu stays sunny and swimmable most of the year.

How do you get around Kauai?

Fly into Lihue Airport on the east side, then rent a car, since no road circles the island and sights are spread from Haena in the north to Waimea and Polihale in the west. Buses and shuttles exist but are limited, so a car is the practical way to reach the canyon, the trailheads, and the beaches.
