Na Pali Coast and the Kalalau Trail

The Na Pali valleys are not empty wilderness in the way they can look from a tour boat. Native Hawaiians lived in these hanging valleys for centuries, terracing the slopes to grow kalo, or taro, in irrigated loi, and fishing the waters below. Kalalau, Nualolo, and Miloli'i valleys held settled communities connected by trail and canoe, and stone wall terraces, house platforms, and heiau remain in the valleys today as evidence of that life.

The name Na Pali means the cliffs. Families farmed and fished here into the late nineteenth and early twentieth centuries, and Kalalau in particular was worked for its taro long after most other valleys had emptied. The archaeological sites in these valleys are protected and sacred to Native Hawaiians, and hikers are asked to leave stone structures, terraces, and any cultural features exactly as they find them.

The modern Kalalau Trail largely follows older Hawaiian routes between the valleys. It was improved in the late nineteenth and early twentieth centuries, and the coast has drawn a long line of hikers, wanderers, and those seeking solitude ever since, which is part of why the permit and reservation systems exist today.

Kauai is the oldest of the main Hawaiian islands, roughly five million years old, and Na Pali shows what time does to a volcano. The island was built by lava from a shield volcano, and once the eruptions stopped, water went to work. Kauai's interior, around Mount Waialeale, is among the wettest places on earth, and all that rain pours off the high ground toward the sea.

The sharp vertical flutes that make the cliffs so distinctive are the work of countless small streams cutting parallel grooves down the soft volcanic rock, while the ocean undercuts the base and whole sections collapse into the sea. The result is a coastline of knife-edge ridges, amphitheater valleys, sea caves, and arches that no road could ever cross, which is exactly why none does.

The most-walked stretch is the two miles to Hanakapiai Beach. The first mile climbs to a viewpoint where the coast reveals itself, then descends toward the stream and beach. In summer Hanakapiai has a sandy beach, but in winter the sand strips away to boulders, and in every season the water here is deadly. A hand-painted sign near the beach tallies the many people lost to the surf and rip currents, and the warning is not decorative.

From the beach, a rough two-mile side trail climbs inland to Hanakapiai Falls, a tall ribbon of water dropping into a pool in a green box canyon. The round trip to the falls turns the day into a serious eight-mile outing over slick, rooted ground with multiple stream crossings, and the streams can rise fast and dangerously after rain upslope even when it is dry at the coast.

The waters off Na Pali are alive. Spinner dolphins travel the coast in pods and are known for leaping and spinning clear of the water, and Hawaiian green sea turtles, the honu, feed and surface along the shore. In winter, roughly December through April, humpback whales fill the channel, having traveled thousands of miles from Alaska to breed and calve in Hawaiian waters, and their spouts and breaches are often visible from the trail.

Overhead, white tropicbirds with long streaming tail feathers ride the updrafts against the cliffs, and seabirds nest in the folds of the rock. The endangered Hawaiian monk seal, one of the rarest seals on earth, sometimes hauls out to rest on the beaches, and when one does it is roped off and must be left completely undisturbed.

Summer, roughly May through September, brings calmer north-shore seas, more settled weather, and the return of sand to Hanakapiai. It is the more forgiving time to hike, though the trail can still be muddy and the sun strong.

Winter, roughly October through April, is the north shore's wet and high-surf season. Big swells pound the coast, streams run high, and the trail can be slick and dangerous, but it is also whale season and the waterfalls run their fullest. In any season, weather here can turn quickly, and a dry morning can become a downpour by afternoon.

The Napali Coast, on the northwest shore of Kauai, Hawaii, is one of the most spectacular and dramatic coastlines in the world, a wild expanse of towering green cliffs, hidden valleys, waterfalls, and sea, and the Kalalau Trail is the famous, challenging hiking trail that traverses part of it. The soaring, fluted cliffs of the Napali Coast, rising thousands of feet from the sea and inaccessible by road, are breathtaking, and the strenuous Kalalau Trail winds along the coast, offering unforgettable views for those prepared for its rigors. The coast can also be seen by boat or air. Its stunning, wild beauty makes it a bucket-list destination. A breathtaking and wild coastline, it awes visitors. With its cliffs and trail, the Napali Coast offers a spectacular destination in Hawaii.

The Kalalau Trail is extremely challenging and can be dangerous, with narrow, steep, muddy, and eroded sections along high cliffs with serious drop-offs, stream crossings prone to sudden and deadly flash floods, and remote terrain where injuries and deaths have occurred, so it is only for experienced, fit, and well-prepared hikers, requires permits for its longer sections, and demands great caution, proper gear, water, and attention to weather. Even the first stretch to a beach is strenuous and requires care. Never crossing flooded streams and turning back in bad conditions are vital. Only well-prepared hikers with permits should attempt it, with great caution, on the Kalalau Trail in Hawaii.

You can experience the Napali Coast in several ways: by hiking the challenging Kalalau Trail for those prepared for its rigors and holding required permits, by boat tour along the coast to see the cliffs and sea caves from the water, or by helicopter or air tour for aerial views of the dramatic landscape, since much of the coast is inaccessible by road. Boat and air tours offer stunning views without the trail's dangers, and are popular with many visitors. Choosing the way that fits your ability and preparation lets you enjoy the Napali Coast in Hawaii.

The drier summer months generally bring calmer seas and more settled conditions, making them the best time for boat tours and the safest window for the trail, while winter brings large swells, heavy rain, rougher seas, and greater flash-flood danger, so the calmer season is preferable, especially for the water and trail. Because conditions, permits, and access vary, checking current requirements and weather before you go is essential. For the calmest conditions, aim for the summer months, and always check current conditions and permits, at the Napali Coast in Hawaii.

The Napali Coast and the Kalalau Trail are on the northwest shore of Kauai, Hawaii, with the trail beginning at Kee Beach at the end of the north-shore road, within reach of the Haena caves, the Limahuli Garden and Preserve, and the Hanalei Valley, while boat tours often depart from the west or south. That makes the Napali Coast a spectacular centerpiece to combine with Kee Beach and the other attractions of the Kauai north shore on a visit to Hawaii.
