Day Trips from Kauai: Waimea Canyon, Haena and the Na Pali Coast, Wailua and Polihale

Before the sun clears the mountains, the first cars leave Lihue with coffee in the cupholders, heading for a canyon rim wrapped in mist or a north shore road lined with taro fields. Kauai is small enough that nearly every great outing is a round trip from wherever you sleep. These day trips cover the west side canyon country, the far north, the east coast river and the empty sands at the end of the road.

What are the best day trips from Kauai?

The best day trips from Kauai are the five outings that fan out from the island’s main highway, each one a full morning or a full day in a different landscape.

• Waimea Canyon and Kokee: the deep red gorge and the cool forest above it, for lookouts and short hikes.
• Haena and the Na Pali coast: the wettest, greenest end of the road, with the trailhead of a famous cliffside path.
• Wailua River and Wailua Falls: a gentle east side day of riverboats and a waterfall you can see from the roadside.
• Polihale: a remote, wide beach at the far western end, reached by a rough dirt road.
• Hanalei and Princeville: a bay town, an old pier and a wildlife refuge overlook on the north shore.

The best day trips from Kauai

Waimea Canyon and Kokee

From the south and east sides you drive west along the coast, then climb a winding road into the uplands. The ride takes a good while, so leave early, when the canyon is usually clearest and before clouds slide in. The gorge is about 10 miles long and 3,600 feet deep, and the walls shift color through the day.

Keep climbing to Kokee State Park and Kalalau Lookout, at 4,000 feet, which looks down into Kalalau Valley. The air is much cooler up here than on the coast, so bring a layer. Seven named trails start in the park, among them Pihea, Awaawapuhi and Nualolo Cliffs, and an hour or two on one of them turns a drive into a real outing.

Plan most of a day. Non-Hawaii residents pay $5 per person to enter Waimea Canyon State Park (children 3 and under are free) and $10 per vehicle to park. It suits families, photographers and anyone who wants a break from beach heat.

Haena State Park and the Na Pali coast

The drive north along the coast ends where the road meets the cliffs, past one-lane bridges and waterfalls that appear after rain. Allow a long stretch each way from Lihue, more from the south shore. This is the island’s wettest corner, so showers often cross the hills even on sunny days.

Haena State Park holds the trailhead of the 11-mile Kalalau Trail. A day visitor can walk the first stretch to Hanakapiai Valley, 2 miles in, and turn around. Going beyond that point takes a valid Napali Coast State Wilderness Park camping permit, released 90 days ahead.

Non-Hawaii residents must buy a Park Entry Reservation for $5 per person or a Parking Reservation for $10 per vehicle before arriving, available 30 days ahead. Book the date as soon as you know your plans, since spots go quickly. The park suits walkers in good shoes who like green, wet scenery.

Wailua River and Wailua Falls

This is the easiest outing, a short drive from Lihue up the east coast. Beside the Wailua River, the state park is where hours stretch long each day, and a boat tour goes to the Fern Grotto, a cave wrapped in ferns inside a tropical garden. The cruise carries a fee.

Wailua Falls is a short drive inland from Lihue, where a 200-foot sheer drop is visible from the overlook. Morning light tends to be best for photos, and the flow grows after rain. Neither stop needs more than a few hours, so pair them with lunch in Kapaa.

This day suits families with small children, older travelers and anyone who wants a slow day with little hiking. Wear shoes that can handle damp ground near the falls.

Polihale State Park

Polihale sits at the far end of the west side, past the last town. The last five miles are on an unimproved dirt road, and rain can flood it and make it impassable, so four-wheel drive is advised. Plan a long drive each way from Lihue, plus the slow road in.

What you get is a broad, nearly empty beach backed by dunes, with the Na Pali cliffs rising at one end. Sunset is the draw, though the park closes in the evening, so keep an eye on the clock. The surf here can be strong, so watch the conditions and do not assume the water is gentle.

It suits travelers with the right vehicle who want space and quiet. Camping is allowed at $30 per night per campsite for non-residents, for those who want to stay longer.

Hanalei and Princeville

Hanalei is a bay town on the north shore, an easy drive from Lihue on the main highway. The weathered pier, built in the 1880s for the rice trade and rebuilt in 1912, is now used for fishing and strolling. Black Pot Beach Park beside it is a favorite for watching surfers and paddlers.

The Hanalei River winds about 16 miles from Mount Waialeale to the bay and is an American Heritage River. Up the road in Princeville, the overlook for Hanalei National Wildlife Refuge, 917 acres of taro-patch valley, is open Tuesday through Saturday from 8:30 a.m. to 4:30 p.m. Birds feed in the wet fields below.

In winter, large swells reach the north shore, so check that day’s surf and currents plus any warnings that are posted before you get in the water, and swim only where a lifeguard is on duty. Plan half a day to a full one, and pair it with Haena for a long north shore day.

Day trips from Kauai compared

If you have one day, pick the canyon for views or the north shore for green coast. If the weather is gray, the east side is the easier call. Save Polihale for when you have the right vehicle and a dry spell.

Tour or on your own?

A tour makes sense for the long drives, for boat outings and for places where a guide adds something, such as the riverboat to the Fern Grotto. You hand over the driving and the timing, and you can look out the window.

A rental car suits the canyon, Hanalei and the east side, where you stop when you like and linger at lookouts. The bus is better for a short hop around Lihue than for a day in the uplands. Before booking any tour, ask whether park entry and reservations are included and what happens if a park is closed.

Good to know before you go

After Hurricane Lowell swept by just to the west of Kauai in September 2026 and left roads, trails and parks damaged, the Hawaii Division of State Parks keeps the current status of every park on its Important Park Notices page, and if a park is closed for the day you reserved, your reservation is refunded. The hurricane season runs from June 1 to November 30. Keep a respectful distance from monk seals and sea turtles on any beach stop, and carry a warm layer for the canyon rim.
