8 Best Sights in The East Side, Kauai

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.

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.

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.

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.

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.
