27 Best Sights in Kauai, Hawaii

This 2-mile crescent beach cradles a wide bay in a setting that is quintessential Hawaii: the sea is on one side, and behind you are the mountains, often ribboned with waterfalls and changing color in the shifting light. In winter, Hanalei Bay boasts some of the biggest onshore surf breaks in the state, attracting world-class surfers, and the beach is plenty wide enough for sunbathing and strolling. In summer, the bay is transformed—calm waters lap the beach, sailboats moor in the bay, and outrigger-canoe paddlers ply the sea. Pack the cooler, haul out the beach umbrellas, and don't forget the beach toys because Hanalei Bay is worth scheduling for an entire day, maybe two. Several county beach parks—some with pavilions, and all with ample facilities—can be found along the bay: Black Pot (east bay, between the pier and the river mouth, named for the large cookpot used for traditional communal gatherings here), Hanalei Pavilion (west of Black Pot), and Waioli (west of Hanalei Pavilion, with three parking lots accessed off Weke Road). Amenities: lifeguards; parking (no fee); showers; toilets. Best for: sunset; surfing; swimming; walking.

This 2-mile stretch of coast, with its sand dunes, limestone hills, sinkholes, and the Makauwahi Cave, is unlike any other on Kauai. Remains of a large ancient settlement, evidence of great battles, and the discovery of a now-underwater petroglyph field indicate that Hawaiians lived in this area as early as AD 700. Mahaulepu's coastline is unprotected and rocky, which makes venturing into the ocean hazardous. There are three beach areas with bits of sandy-bottom swimming; however, the best way to experience Mahaulepu is simply to roam, on foot or horseback along the sand or trails. Pack water and sun protection. Access to this beach is via private property. Before driving or hiking here, check current gate hours and conditions as the unpaved road can be closed due to weather, grading, or movie filming. Access is during daylight hours only, so be sure to depart before sunset or risk getting locked in for the night. Amenities: parking (no fee). Best for: solitude; sunrise; walking.

At the most popular beach on the South Shore, the snorkeling and swimming are good during calm seas; when the surf's up, the bodyboarding and surfing are good, too. Frequent sunshine, grassy lawns, play equipment, and easy access add to the appeal, especially with families. The endangered Hawaiian monk seal often makes an appearance, and if you stop by just after sunset, you're likely to witness record numbers of protected green sea turtles coming ashore to sleep. (Please stay at least 10 feet away and do not photograph with flash.) Take a walk west on a path fronting numerous resorts. Note that at the time of writing, this beach is one of a few on Kauai that may institute a parking fee for nonresidents. Amenities: food and drink; lifeguards; parking (no fee); showers; toilets. Best for: snorkeling; sunbathing; swimming.

Two restored camp houses, dating from the days when sugar was the main agricultural crop on the Islands, have been converted into a museum, visitor center, snack bar, and gift shop. About 3,100 acres of McBryde sugar land have become Hawaii's largest coffee plantation, with its 4 million trees producing more than half of the state's beans. You can walk among the trees; view old grinders and roasters; watch a video to learn how coffee is grown, harvested, and processed; sample various estate roasts; and check out the gift store.

The center offers free self-guided tours through a small coffee grove (about 20 minutes); a personalized one-hour "Coffee on the Brain" tour for $25; and a "seed-to-cup" farm tour in an open-air truck for $45. From Kalaheo, take Route 50 in the direction of Waimea Canyon (west) and veer left onto Route 540. It's 2½ miles from the Route 50 turnoff.

A beacon for sea traffic since it was dedicated in 1913, this National Historic Landmark has the world's largest clamshell lens in a lighthouse and stands within a wildlife refuge where thousands of seabirds soar on the trade winds and nest on the steep ocean cliffs. It's well worth the site's modest entry fee to see nene geese (the state bird, a threatened species), white- and red-tailed tropic birds, and more (identifiable by educational signboards), as well as native plants, dolphins, humpback whales (in season), the huge winter surf, and gorgeous North Shore views. The gift shop has a great selection of books about the island's natural history and an array of unique merchandise, with all proceeds benefiting education and preservation efforts. Advance reservations are required via  recreation.gov.

Narrow Limahuli Valley, with its fluted mountain peaks and ancient stone taro terraces, creates an unparalleled setting for this botanical garden and nature preserve, one of the most gorgeous spots on Kauai and the crown jewel of the National Tropical Botanical Garden. Dedicated to protecting native plants and unusual varieties of taro, it represents the principles of conservation and stewardship held by its founder, Juliet Rice Wichman. Limahuli's primordial beauty and strong mana (spiritual power) eclipse the extensive botanical collection. Call ahead to check if guided tours are being offered, or tour on your own. A reservation is required to park here, though North Shore Shuttle riders are exempt. Check out the quality gift shop and revolutionary compost toilet, and be prepared to walk a somewhat steep hillside.

Tucked away in Lawai Valley, this collection of gardens includes lands and a cottage once used by Hawaii's Queen Emma (1836–85) for a summer retreat. Trams depart frequently to transport people from the visitor center to the gardens. The rambling 252-acre McBryde Garden has exhibits and easy trails to help visitors learn about biodiversity and plants collected throughout the tropics, including a Canoe Garden that features plants introduced to Hawaii by early Polynesian voyagers.  The biodiversity path in McBryde is accessible for people with mobility issues. The 100-acre Allerton Garden, which can be visited only on a guided tour, artfully displays statues and water features originally developed as part of a private estate. A famous scene in Jurassic Park was filmed here.

Reservations and closed-toe shoes are required for all tours. The visitor center has a high-quality gift shop and grab-and-go refreshments. Besides propagating rare and endangered plants from Hawaii and elsewhere, NTBG functions as a scientific research and education center. The organization also operates gardens in Limahuli, on Kauai's North Shore; in Hana, on Maui's East Shore; and in Florida.

When conditions are right, a natural blowhole in the rocky shoreline behaves like Old Faithful, shooting salt water high into the air and making a hollow echoing sound. It's most dramatic during big summer swells, which jam large quantities of water through the ancient lava tube with great force. Most sidewalk vendors hawk inexpensive souvenirs, but a few carry locally set South Sea pearls or rare Niihau-shell creations, with prices ranging from affordable to several thousand dollars. Look for green sea turtles bobbing in the adjacent cove.

Kauai has plenty of noteworthy waterfalls, but this one is especially gorgeous, easy to find, and easy to photograph from the road. You may recognize the impressive cascade from the opening sequences of the Fantasy Island television series. To reach it, drive north from Lihue following Maalo Road in Hanamaulu, then travel uphill for 3 miles.  Do not hike down to the base of the falls to access the water.

A great family park, Anini features one of the longest and widest fringing reefs in all Hawaii, creating a shallow lagoon that is good for snorkeling and kids splashing about, even though there are no lifeguards. It is safe except for when strong currents are created by the surf raging outside the reef. A rip current exists between the two reefs where the boats enter and exit the beach ramp, so avoid swimming there. The entire reef follows the shoreline for some 2 miles and extends 1,600 feet offshore at its widest point. There's a narrow ribbon of sandy beach with lots of grass and shade, as well as a county campground at the western end and a small boat ramp. Amenities: parking (no fee); showers; toilets. Best for: sunrise; swimming; walking.

There aren't many safe swimming beaches on Kauai's East Side; however, this one ranks highly with parents because there's typically a narrow lagoon-like area between the beach and the reef that is perfect for small children. In winter, watch for east and northeast swells that would make this not such a safe option. There are no beach facilities or lifeguards, so watch your babies. A shower spigot along the roadside provides cold water to rinse off the salt. Amenities: parking (no fee); showers. Best for: sunrise; swimming.

Built in 1892, the historic Hanalei Pier can be seen from miles across the bay and is a great spot for photos or taking a leisurely stroll; it attracts a gathering every sunset. The pier came to fame when it was featured in the award-winning 1957 movie South Pacific. Fishers fish here, and picnickers picnic. The pier was refurbished after flooding in 2018.

This narrow, pedestrian-only bridge may not be the biggest adventure on Kauai, but it's enough to make your heart hop. What is interesting is that it's not just for show: it actually provides the only access to taro fields across the Hanapepe River. Considered a historic suspension bridge even though it was rebuilt in 1996 after the early-1900s original was destroyed—like so much of the island—by Hurricane Iniki, the bridge was also repaired following flood damage in 2019. If you're in the neighborhood, it's worth a stroll.

Rice grew in the taro fields of Hanalei Valley for almost 80 years—beginning in the 1880s and ending in the early 1960s—and today this history is embodied in the Haraguchi family, whose ancestors threshed, hulled, polished, separated, graded, and bagged rice in their 3,500-square-foot rice mill. It was demolished once by fire and twice by hurricanes, and damaged by flooding in 2018 and 2021. Rebuilt to the standards of the National Register of Historic Places, the mill—with neighboring taro fields—is typically open for tours on a limited schedule mainly due to endangered-bird nesting areas. At the time of writing, tours were not available, but check the website or Instagram (@HanaleiTaro) for updates. The family still farms taro on the onetime rice paddies and also operates the Hanalei Taro & Juice Co. kiosk in Hanalei Town; see  hanaleitaro.com. All proceeds from the historic rice mill go to nonprofit education programs.

Five minutes south of the airport in Lihue, you'll find this wide beach and sandy-bottom bay fronting Marriott's Kauai Beach Club. It's almost always safe from rip currents and undertows because it's around the back side of a peninsula, in its own cove. Tons of activities take place here, including all the usual water sports—beginning and intermediate surfing, bodyboarding, bodysurfing, and swimming. In addition, two outrigger canoe clubs paddle in the bay, and the Nawiliwili Yacht Club's boats sail around the harbor. Kalapaki is the only place on Kauai where double-hulled canoes are available for rent (at Kauai Beach Boys, which fronts the beach next to Duke's Kauai restaurant). Visitors can also rent snorkel gear, surfboards, bodyboards, and kayaks from Kauai Beach Boys, as well as sign up for surf lessons and sunset boat tours. A volleyball court on the beach is often used by a loosely organized group of local players; visitors are always welcome. Avoid the stream on the south side of the beach; it often has high bacteria counts. Duke's Kauai is one of only a couple of restaurants on the island actually on a beach. The restaurant's lower level is casual—even welcoming beach attire and sandy feet—making it perfect for lunch or an afternoon cocktail. Amenities: food and drink; lifeguards; parking (limited, no fee); showers; toilets; water sports. Best for: surfing; swimming; walking.

This estate—once a much larger plantation and now a farm and visitor attraction—dates back to 1850, shortly after the Great Mahele, the division of land by the Hawaiian people. Plantation manager Albert Spencer Wilcox developed it as a working cattle ranch, and it was also a sugar plantation. His nephew, Gaylord Parke Wilcox, took over in 1936, building Kauai's first mansion. Today the 16,000-square-foot Tudor-style home houses specialty shops, art galleries, the Koloa Rum Company, Luau Kalamaku, and Gaylord's, a pretty restaurant with courtyard seating. Nearly half the original furnishings remain, and the gardens and orchards were replanted according to the original plans. You can tour the grounds for free or take a 40-minute train ride, which includes a chance to feed farm animals while learning the agricultural story of Kauai and viewing a working farm. A more expensive train tour includes lunch and fruit-picking in the orchard.

A great place to start your visit in Kokee State Park, the museum has friendly staff who are knowledgeable about trail conditions and weather, as well as informative displays and a good selection of books about the area's unique native flora and fauna and social history. You may find that special memento or gift you've been looking for. Note that there's generally no cell phone service in the park.

This 4,345-acre wilderness park reaches 4,000 feet above sea level, an elevation that affords you breathtaking views and a cooler, wetter climate that's in marked contrast to the beach. You can gain a deeper appreciation of the island's rugged terrain and dramatic beauty from this vantage point. Large tracts of native ohia and koa forest cover much of the land, along with many varieties of both native and introduced plants. Hikers can follow a 45-mile network of trails through diverse landscapes that feel wonderfully remote—until the tour helicopters pass overhead. The small nonprofit museum provides park information, and the lodge offers hearty lunches. Note that there's generally no cell phone service in the park.

Translated as "Torchlight of the God Lono," Kukuiolono has serene Japanese gardens, a display of significant Hawaiian stones, a meditation pavilion, and spectacular panoramic views of the south and west shorelines. This quiet hilltop park is one of Kauai's most scenic areas and is ideal for a picnic or easy hike through an ironwood grove. The nine-hole golf course has the island's least expensive fees, and there's a new minigolf activity. If the café is open, it's a good spot for lunch with a view. Nongolfers can explore walking paths with interpretive signage; just stay alert.

This is a great beach to sit and people-watch as diving and fishing boats, kayakers, and canoe paddlers head out to sea. Shore and throw-net fishermen frequent this harbor as well. It's not a particularly large harbor, so it retains a quaint sense of charm, unlike Nawiliwili Harbor or Port Allen. The lawn is a good picnic and ball-tossing spot, and the bay is a nice protected area for limited swimming, but with all the boat traffic kicking up sand and clouding the water, it's not good for snorkeling. Outside the breakwater, there is a decent surf spot. Amenities: parking (no fee); showers; toilets. Best for: picnics; sunset; swimming.

Hawaii is the only state in the country where Theobroma cacao grows—the tree whose seeds become chocolate—and the Lydgates are on a mission to grow enough cacao on their multigenerational family farm that one day they will produce an identifiable Kauai homegrown chocolate. For now, you can tour this 46-acre farm (in addition to cacao, they grow vanilla, timber trees, bamboo, and many tropical fruits) and learn how chocolate is made, "from branch to bar," as they put it. The three-hour tour includes, of course, plenty of chocolate tastings. Reservations are required for the morning tour, which runs weekdays at 9 am.

This is by far the best family beach park on Kauai: the waters off the beach are protected by a hand-built breakwater, creating two boulder-enclosed saltwater ponds for safe swimming and snorkeling most of the year. Heavy rains upriver do occasionally deposit driftwood and clog the ponds, and strong trade winds can cause waves to wash over. The smaller of the two ponds is perfect for keiki. Behind the beach is Kamalani Playground; children of all ages—that includes you—enjoy the swings, lava-tube slides, tree house, and open field. Picnic tables abound in the park, and pavilions for day use and overnight camping are available by permit. The Kamalani Kai Bridge is a second playground, south of the original. (The two are united by the Ke Ala Hele Makalae bike and pedestrian coastal path.) This park system is perennially popular; the quietest times to visit are early mornings and weekdays. Amenities: lifeguards; pavilions; camping; parking (no fee); showers; toilets. Best for: partiers; sunrise; swimming; walking.

The mighty Wailua River produces many dramatic waterfalls, and Opaekaa (pronounced "oh-pie-kah-ah") is one of the best, plunging hundreds of feet to the pool below. It can be easily viewed from a scenic overlook with ample parking. Opaekaa means "rolling shrimp," which refers to the tasty native crustaceans that were once so abundant they could be seen tumbling in the falls. Do not attempt to hike down to the pool. Just before reaching the parking area for the waterfall, turn left into a scenic pullout for great views of the Wailua River and its march through the valley to the sea.

A great family spot, Salt Pond Beach Park features a naturally made, shallow swimming pond behind a curling finger of rock where keiki (children) splash and snorkel. This pool is generally safe except during a large south summer swell. The center and western edge of the beach are popular with bodyboarders and bodysurfers. The beach is also an easy spot to see stilts, tattlers, shearwaters, and other seabirds, as well as an occasional resting monk seal. Pavilions with picnic tables offer shade, and there's a campground that tends to attract a rowdy bunch at the eastern end. On a cultural note, the mudflat behind the beach is the last spot in Hawaii where salt is harvested in the dry heat of summer, using pans passed down within families. The park is popular with locals, and it can get crowded on weekends and holidays. Amenities: lifeguard; parking (no fee); showers; toilets. Best for: sunset; swimming; walking.

Nestled next to Wailua Marina along the mighty Wailua River, this 30-acre botanical and cultural garden offers a glimpse of distinctive foliage, including 20 types of fruit trees, a bamboo rain forest, and tropical lagoons. Enjoy a stroll along a mile of pathways. It's a popular spot for wedding receptions and other large events, and its luau is one of the island's oldest and best.

The first hotel built in Poipu in 1962 overlooked this beach, adjacent to Poipu Beach Park. Actually, there's little to distinguish where this one ends and the other begins, other than a crescent reef at the eastern end of Waiohai Beach. That crescent, however, is important. It creates a small protected bay—good for snorkeling and beginning surfers. However, when a summer swell kicks up, the near-shore conditions become dangerous; offshore, there's a splendid surf break for experienced surfers. The beach itself is narrow and, like its neighbor, gets very crowded in summer. Amenities: parking (no fee). Best for: snorkeling; sunset; surfing; swimming.

Cultural information and local exhibits about sugar, weaving, shells, and poi-making highlight this small museum-style resource center in Waimea Town. Shop counters offer Island-made items, Niihau-shell jewelry, photographs of Kauai, children's books, and snacks. Lei-making and music sessions happen regularly on the patio, and you can get a map for a walking tour.
