10 Best Sights in Princeville and Kilauea, Kauai

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.

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.

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.

You wouldn't know it today, but this beach on Kilauea Bay was once an interisland steamer landing and a rock quarry. Today, it's a fairly quiet beach—although when the surf closes out many other North Shore surf spots, the break directly offshore from Kilauea Stream near the abandoned quarry is still rideable. For the regular oceangoer, summer's the best bet, although the quickly sloping ocean bottom makes for generally treacherous swimming. The stream estuary is quite beautiful, and the ironwood trees and false kamani growing in the generous sand dunes at the rear of the beach provide protection from the sun. It's a wonderful place to observe seabirds. Amenities: none. Best for: solitude; surfing; walking.

A winding road leads down a cliff face to picture-perfect Kalihiwai Beach, which fronts a bay of the same name. It's another one of those drive-up beaches, so it's very accessible. Most people park under the grove of ironwood trees, near the stream, where young kids like to splash and older kids like to bodyboard.  The stream carries leptospirosis, a potentially lethal bacteria that can enter through open cuts. In winter months, beware of a treacherous shore break. Summer is the only truly safe time to swim. The local-favorite winter surf spot off the eastern edge of the beach is for advanced surfers only. Toilets here are the portable kind, and there are no showers. Amenities: parking (no fee); toilets. Best for: solitude; surfing; swimming; walking.

This beach was relatively unknown—except by local fishers, of course—for a long time, hence the common reference to it as "Secret Beach." You'll understand why once you stand on the coarse white sands of Kauapea and see the solid wall of rock that runs the length of the beach, making it fairly inaccessible. For the hardy, there is a steep hike down the western end. From there, you can walk for a long way in either direction in summer. During winter, big swells cut off access to sections of the beach. You may witness dolphins just offshore, and it's a great place to see seabirds, as Kilauea Point National Wildlife Refuge and its historic lighthouse lie at the eastern end. Nudity is not uncommon, though it is illegal in Hawaii. A consistent onshore break typically makes swimming here very dangerous. On big-surf days, don't go near the shoreline. Amenities: parking (no fee). Best for: solitude; sunrise; walking.

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.

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.

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.

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.
