44 Best Sights in Kauai, Hawaii

The long wide fringing reef is this beach's trademark. The waters near shore are generally too shallow for swimming; if you go in, wear a rash guard to protect against prickly sea urchins and sharp coral on the bottom. This area is known for its tricky currents, especially during periods of high surf, and has been the site of numerous drownings. It can be dangerous to snorkel here. There's some nudity at the western end. Accessing this long strand of coarse white sand requires hiking down a steep rocky trail that is slippery when wet. Amenities: parking (no fee). Best for: solitude; sunrise; walking.

Named in honor of the first Native Hawaiian schoolteacher, this beach is on the western bank of the Waimea River. It is also where Captain James Cook first came ashore in the Hawaiian Islands in 1778. If that's not interesting enough, the sand here is not the white powdery kind you see along the South Shore. It's a salt-and-pepper combination of pulverized black lava rock and lighter-color reef. Unfortunately, the intrigue of the beach doesn't extend to the waters, which are reddish and murky (thanks to river runoff) and choppy (thanks to an onshore break). Don't swim here after heavy rains. Instead, watch the local outrigger canoe club head out or stroll the Waimea State Recreational Pier, from which fishers drop their lines, about 100 yards west of the river mouth. Amenities: parking (no fee); showers; toilets. Best for: sunset; walking.

Famous as the beach where Nurse Nellie washed that man right out of her hair in South Pacific, Lumahai is picturesque, with a river and ironwood grove on the western end and stands of hala (pandanus) trees and black lava rock on the eastern side. In between is a long stretch of olivine-flecked sand that can be wide or narrow, depending on the surf. The beach can be accessed in two places from the highway; one involves a steep hike from the road. Avoid swimming and water activities here—the ocean can be dangerous, with a snapping shore break year-round and monster swells in the winter; in addition, the current can be strong near the river. Parking is very limited, along the road or in a rough dirt lot near the river. Amenities: none. Best for: solitude; sunset; walking.

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.

Across the highway from Haena Beach Park is Maniniholo Dry Cave, a place steeped in legends. You can walk for a few minutes through a 30-yard-long cave, which darkens and becomes more claustrophobic as you glide across its sandy floor, hearing the drips down the walls and wondering at its past. Legend has it that Maniniholo was the head fisherman of the Menehune—Kauai's quasi-mythical first inhabitants. After gathering too much food to carry, Maniniholo's men stored the excess under a cliff overnight. When he returned in the morning, the food had vanished, and he blamed the imps living in the cliff's cracks. He and his men dug into the cliff to find and destroy the imps, leaving behind the dry cave.

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.

This is actually two very small pocket beaches separated by a slender rocky point. The narrow beach area can all but disappear in wintertime. However, in summer, the steep rocky trail (don't trust the rusty handrails and rotting ropes) that provides access reduces the number of beachgoers, at times creating a deserted beach feel. Winter's high surf creates dangerous conditions. The parking lot is small. Don't attempt the trail after a heavy rain—it turns into a mudslide. Amenities: parking (no fee). Best for: sunset; surfing.

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.

The coastline along the community of Princeville is primarily made up of sea cliffs with a couple of pocket beaches. The sea cliffs end with a long narrow stretch of beach just east of the Hanalei River. Public access is via 100-plus steps around the back of 1 Hotel Hanalei Bay; hotel guests can take the elevator to sea level. The beach itself is subject to the hazards of winter's surf, narrowing and widening with the surf height. On calm days, snorkeling is good thanks to a shallow reef system pocked with sand. Sometimes a shallow sandbar extends across the river to Black Pot Beach Park, part of the Hanalei Beach system, making it easy to cross the river. On high-surf days, the outer edge of the reef near the river draws internationally ranked surfers. The 1 Hotel Hanalei Bay pool is off-limits to nonguests, but the hotel's restaurants and bars are not. Note that parking is limited. Amenities: food and drink; parking (no fee). Best for: snorkeling; sunset; surfing.

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.

The Colonel Zephaniah Spalding Monument commemorates the Civil War veteran who purchased this splendid property overlooking an area from Anahola to Kapaa in 1876 and established what became the Kealia Sugar Plantation. To reach it, turn onto Kealia Road toward the mountains, just after Mile Marker 10. Immediately on your right is a small post office and, on your left, rodeo grounds sometimes in use on summer weekends. The very rough road ascends, and 2½ miles later you'll reach a grassy area with the concrete remains of a monument, though all the interpretive signs have been destroyed.

Located at the mouth of Hawaii's only navigable river, Wailua Beach has considerable cultural significance. Petroglyphs carved on boulders are sometimes visible near the river mouth during low-tide conditions. Surfers and stand-up paddlers enjoy this beach, and many families spend weekend days in the cool shade under Wailua Bridge, even hauling out their portable grills and tables to go with their beach chairs. The great news about Wailua Beach is that it's almost impossible to miss; however, parking can be a challenge. The best parking for the north end of the beach is on Papaloa Road behind the Shell station. For the southern end of the beach, you can park at Wailua River State Park and cross the highway at the traffic light. Amenities: parking (no fee). Best for: surfing; swimming; walking; windsurfing.

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.
