6 Best Sights in Kauai, Hawaii

Joyce and Ed Doty's love for plants and art spans the 240 acres here and includes many different gardens, a hardwood plantation, an ahupuaa (a Hawaiian land division), a re-created Navajo compound, an Athabascan village, a Japanese teahouse, a hedge maze, a waterfall, and access to a sandy beach. Throughout the grounds are more than 200 bronze sculptures, one of the nation's largest collections. One popular feature is a children's garden with a 16-foot-tall Jack and the Beanstalk bronze sculpture, gecko maze, tree house, kid-size train, and, of course, a tropical jungle. Located in a residential neighborhood and hoping to maintain good neighborly relations, the nonprofit organization limits tours. Tour lengths vary from 1½ to 5 hours. Reservations are required for all tours, including the self-guided stroll.

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.

Tree-lined and grassy, this arboretum in the Lihue-Koloa Forest Reserve is a perfect spot for a picnic—and there are lots of picnic tables scattered throughout the parklike setting. A typically shallow, cascading stream makes for a fun spot for kids to splash, although the water's a bit chilly. After crossing the stream on the bridge, the 1-mile walking trail meanders through mango, monkeypod, and exquisite rainbow eucalyptus trees. This is usually a peaceful place, but pay attention to the weather as the stream can flood quickly.

Set on a private estate on the mauka (mountain side) of Kam Highway across from Princeville, these well-tended gardens include a diverse collection of native and “canoe” plants (brought by Polynesians), plus medicinal, rare, and endangered flowers. Visitors can join three-hour guided tours of the entire property, usually offered four mornings a week at 9:30 am. Tours include samples of seasonal fruit and honey from on-site beehives and a half-hour chocolate tasting. Reservations are required (no self-guided tours); book early, as tours fill well in advance.

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.
