15 Best Sights in The South Shore, Kauai

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.

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.

Koloa’s first sugar plantation opened in 1835, ushering in an era of sugar production throughout the Islands, with more than 100 plantations established by 1885. Many of the workers came from the Philippines, Japan, China, Korea, and Portugal, creating Hawaii’s multiethnic mélange. Today, many of Koloa’s historic buildings, beneath the shade of stately old monkeypod trees, have been converted into fun shops, galleries, and places to eat. Even the newer developments mimic quaint plantation-camp architecture. You’ll just want to stroll and take it all in. Indulge in a sweet treat like a shave ice, freshly roasted gourmet nuts, or a healthy smoothie after a food-truck lunch taken to nearby Knudsen Park. Be sure to approach Old Koloa Town via the Tree Tunnel, a romantic canopy of eucalyptus trees planted more than a century ago along a stretch of Maluhia Road.

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.

Don't pack the beach umbrella, mats, and cooler for this one—just your snorkel gear, when the seas are calm. This beach—named after neighboring restaurant The Beach House, located along the road to Spouting Horn—is a small slip of sand during low tide and a rocky shoreline when it's high; however, it is conveniently located by the road's edge, and its rocky edge and bottom make it great for snorkeling. (As a rule, sandy-bottom beaches are not great for snorkeling. Rocks provide safe hiding places and grow the food that fish and other marine life like to eat.)

A sidewalk along the coastline on the restaurant side of the beach makes a great vantage point from which to peer into the water and look for honu, the Hawaiian green sea turtles. It's also a very popular gathering spot to watch the sun set. You can park in the tiny public lot across from the beach.  Make reservations for dinner at The Beach House in advance, and time it around sunset. Amenities: parking (no fee); showers; toilets. Best for: snorkeling; sunset; surfing.

This beach is synonymous on Kauai with bodysurfing, thanks to its shallow sandbar and reliable shore break. Because the beach is small and often congested, surfboards are prohibited near shore. The water on the rocky eastern edge of the beach is a good place to see endangered green sea turtles noshing on plants growing on the rocks. Monk seals sometimes haul out here; please allow them to rest. Playground equipment is available, and there's free street parking. Amenities: food and drink. Best for: sunset; surfing.

Stone masons are rebuilding the walls of this largely intact 13-acre Hawaiian village dating back to the mid-1400s. Fishponds, taro patches, a temple, and a festival arena eventually will be restored, serving as a cultural learning center for residents and visitors. You can walk around the outside and check out the statues and signage; restoration is in phase three and the interior is set to open in 2025.

The Hawaiian name for this stretch of beach, Keoneloa, means "long sand," but many refer to this beach fronting the Grand Hyatt Kauai Resort & Spa as Shipwreck Beach. Both make sense. It is a long stretch of crescent beach punctuated by stunning sea cliffs on both ends, and, yes, a ship once wrecked here. With its rough onshore break, the waters off "Shippies" are best for bodyboarding and bodysurfing experts; however, the beach itself is plenty big for sunbathing, sandcastle building, Frisbee throwing, and other beach-related fun. The eastern edge of the beach is the start of an interpretive cliff and dune walk (complimentary) held by the hotel staff; check with the concierge for days and times, and keep an eye out for snoozing monk seals below. Parking is limited. Amenities: food and drink; parking (no fee); showers; toilets. Best for: surfing; walking.

Throughout the South Shore, you'll find brass plaques with details of historical stops along the 10-mile Koloa Heritage Trail. Start at Spouting Horn in Poipu and bike it, hike it, or drive it—your choice. You'll learn about Koloa's whaling history, sugar industry, ancient Hawaiian cultural sites, the island's volcanic formation, and more. Pick up a free self-guided trail map at shops in Koloa Town or download a PDF from  poipubeach.org.

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.

Spend a serene morning in Lawai Valley, a pastoral corridor that joins verdant hills to the beach where Queen Emma (1836–85) had a home. In 1904, Japanese plantation workers created a miniature version of the famed 88 temples of Shikoku so they could complete a sacred pilgrimage despite being far from home. This is the only replica of this temple route outside Japan and one of the country's oldest Buddhist sites. Ancient Hawaiians built a heiau (temple) in Lawai, and then each group of immigrants that followed––Chinese, Japanese, Portuguese, and Filipino––built their own places of worship in this area known for its healing waters.

Engulfed by vegetation for decades, this hillside dotted with knee-high shrines was excavated and restored by volunteers, who now offer bimonthly tours. After a welcome of tea and manju (Japanese cookies) and a short presentation, you can borrow a walking staff to wind your way up an orchid-lined path for a silent stroll; be sure to peek into the handmade shrines that house small statues---some are historic, and others were made during the pandemic by Hawaii's most well-known artists. Afterward, visitors may enter the 13th-century-style Hall of Compassion, built without nails under the guidance of Japanese master carpenters.  Reservations are required by phone, text, or email. Arrive 15 minutes early and wear comfortable shoes.

A field next to Prince Kuhio Condominiums honors the birthplace of Kauai's beloved Prince Jonah Kuhio Kalanianaole. Known for his kind nature and tireless work on behalf of the Hawaiian people, he lost his chance at the throne when Americans staged an illegal coup against Queen Liliuokalani in 1893 and toppled Hawaii's constitutional monarchy. He served as a delegate to the U.S. Congress for 19 years after Hawaii became a territory in 1900. An annual commemoration is held around his March birthday, a state holiday. This is a great place to watch wave riders surfing a popular break known as PKs, or to see the sun sink into the Pacific.

Off Route 50 as you head from Lihue to the South Shore, Route 520 (Maluhia Road) is known locally as "Tree Tunnel Road," due to the avenue of tall eucalyptus trees lining both sides. A drive here is a lovely introduction to the area. The trees were planted at the turn of the 20th century by Walter Duncan McBryde, a Scotsman who began cattle ranching on Kauai's South Shore. The canopy of trees was ripped to literal shreds twice—in 1982 during Hurricane Iwa, and then again in 1992 during Hurricane Iniki. And, true to Kauai's resilience, both times the trees grew back into an impressive tunnel.

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.
