In this rugged corner of Hawaii, waterfalls drop 4,000 feet from valleys older than memory

Sixteen miles you can’t drive to

No road reaches the Na Pali Coast. Not one.

This 6,175-acre wilderness park runs 16 miles along the northwest shore of Kauai, and the only way in is by foot, boat, or helicopter.

The name means “many cliffs” in Hawaiian, and those cliffs rise up to 4,000 feet straight from the Pacific. Deep valleys cut between them, and waterfalls drop from green ridgelines right into the ocean.

You get here on the coast’s terms, not yours, and that’s exactly what makes it worth the effort.

Polynesian farmers built stone terraces in these valleys

Millions of years of water carved the Na Pali Coast, cutting deep valleys into the northwest face of the island. Polynesian navigators settled here around 1200 AD and built whole communities along the valley floors.

They grew taro, a starchy root crop similar to the potato, on stone-walled terraces they carved into the land. You can still find the remains of those terraces in the Kalalau and Hanakoa valleys today.

The last native Hawaiians known to live along this coast left in the early 20th century.

The Kalalau Trail crosses five valleys in 11 miles

The Kalalau Trail is the only way to walk the Na Pali Coast.

It runs 11 miles from Ke’e Beach to Kalalau Beach, crossing five major valleys and gaining about 800 feet in elevation along the way.

Crews originally built the trail in the late 1800s, then rebuilt sections between 1935 and 1937. The path never levels out.

It climbs above sea cliffs, drops into valleys, narrows along steep ocean-side drop-offs, and sends you through stream crossings. This trail earns its “difficult” rating.

Half a mile in and the coastline opens up

If the full 11-mile trail sounds like too much, the first two miles to Hanakapiai Beach make a solid day hike. Within half a mile, the coastline spreads out in front of you.

The round trip takes about three to four hours, so you don’t need to start at dawn. One thing to know before you go: skip the swimming at Hanakapiai Beach.

Strong rip currents and rough surf make wading dangerous.

You also need a day-use entry and parking reservation at Haena State Park before you hit the trailhead.

A 300-foot waterfall waits two miles past the beach

From Hanakapiai Beach, a side trail heads two miles inland through rainforest and across several stream crossings to Hanakapiai Falls.

The visible drop runs about 300 feet into a pool at the base, and after the hike to get there, that pool is exactly where you want to end up for a swim.

The full round trip from the trailhead covers about eight miles, so plan on at least six hours. You earn every step, and the falls make good on the promise.

Five nights maximum and no drinking water anywhere

Going past Hanakapiai means you need a camping permit. Two designated camping areas sit along the trail: Hanakoa at mile six and Kalalau Beach at the end.

You can stay up to five nights total in the park, but you cannot camp two nights in a row at Hanakapiai or Hanakoa. The campsites have composting toilets and nothing else.

No tables, no drinking water.

Permits sell out months ahead of time, especially in summer, so book early through the Hawaii state parks system.

Honopu Beach was once a burial ground for chiefs

Kalalau Beach sits at the trail’s end, a stretch of white sand backed by fluted cliffs and fed by a small waterfall.

Just down the coast, Honopu Beach splits into two sections divided by a natural stone arch that towers over the sand.

Hawaiians once used Honopu as a burial ground for their chiefs, and visitors should treat the area with deep respect. No road reaches any of these beaches.

You get there by trail, boat, or helicopter. Further south, Milolii Beach opens to kayak camping during the summer months.

A waterfall pours right over the mouth of Pirates Cave

The Pacific has spent thousands of years carving sea caves and arches into the Na Pali cliffs.

Pirates Cave, also called Waiahuakua Cave, is one of the tallest and deepest, with a waterfall pouring over its entrance.

The Double Doors Cave ranks among the longest sea caves in the world, and the Honopu Sea Cave has pink and red coral growing along its dark lava walls.

Small boats and rafts can slip inside some of these caves when the ocean cooperates, but access depends entirely on conditions that day.

Artifacts sit six feet deep at this ancient fishing village

Nualolo Kai is an ancient Hawaiian fishing village tucked at the base of the cliffs, reachable only by a permitted boat.

Starting in 1958, the Bishop Museum dug into this site and pulled up fishhooks, coral files, and other artifacts buried as deep as six feet below the surface.

It remains one of the most studied archaeological sites in all of Hawaii. A large barrier reef protects the beach and creates some of the best snorkeling on Kauai.

Hawaiian monk seals rest on the shore here, and green sea turtles feed along the reef.

Humpback whales nurse their calves just offshore

Spinner dolphins travel alongside boats in large pods along the Na Pali Coast, and you can spot Hawaiian green sea turtles while snorkeling the reefs.

Endangered Hawaiian monk seals haul out on the remote beaches, especially at Nualolo Kai. From December through March, humpback whales move into these waters to breach and nurse their calves.

The reefs along the coast support hundreds of fish species, and about a third of them live only in Hawaiian waters. Bring a mask if you go by boat.

The 4,000-foot lookout fills with clouds by midday

Helicopter tours cover the cliffs, valleys, and waterfalls that you cannot reach any other way. But you don’t need a helicopter to see the coast from above.

The Kalalau Lookout in Kokee State Park sits at about 4,000 feet and gives you a drive-up view straight into the Kalalau Valley and out to the ocean.

About a mile further, the Puu O Kila overlook sits higher with an even wider view. Go in the morning before the clouds roll in.

Kokee State Park also has over 45 miles of trails, some leading to ridgetop views of the Na Pali valleys.

Book your permits 90 days out or you’ll miss the window

Every non-resident visitor needs a reservation to enter Haena State Park, which is the gateway to the Kalalau Trail.

Hawaii residents with a valid state ID can walk in for free on a first-come, first-served basis. Camping permits go live 90 days in advance through the Hawaii state parks system.

Boat companies that bring passengers to shore need their own permits, and from May 15 through Sept. 7, ocean access by boat or kayak to certain areas requires a valid camping permit.

Hit the trails at Na Pali Coast State Wilderness Park

You can reach the Na Pali Coast through Haena State Park on Kauai’s north shore, where the Kalalau Trail starts at Ke’e Beach.

Non-residents need reservations for park entry at $5 per person, plus $10 for parking.

The park opens daily at 7 a.m. Camping permits go live 90 days out through the state parks reservation system and cost $35 per person, per night. Hawaii residents with valid state ID enter free.

Book early, because permits and parking slots sell out fast.
