66 Best Sights in Big Island, Hawaii

Thanks to Hilo's abundant rainfall, this lava tube is lush with plant life. Concrete stairs lead down to the 2½-mile-long tube, which has no lighted areas. The ground is uneven and damp, so wear sturdy shoes, bring a flashlight, and explore as far as you dare to go. There are restrooms and a covered picnic table at the cave, and parking across the street. Heed all warning signs when entering the caves.

Buildings here have been restored to their original 1920s and '30s vintage plantation styles. Although most shopping is along Kamehameha Avenue two blocks below, the ambience on Keawe Street offers a nostalgic sampling of Hilo as it might have been decades ago.

On the northernmost stretch of the park's coastline, this lovely beach fronts an absolutely beautiful bay with crystal-clear, deep aquamarine water. It's peaceful in summer, but the park's paved entrance, amenities, and parking lot make the beach very accessible and, as a result, often crowded. Fine white sand sits in stark contrast to old black lava flows, and there's little shade—bring umbrellas. Rocky shores on either side protect the beach from afternoon winds and offer some fabulous snorkeling spots. Gates open daily from 8 to 7. In winter, surf can get rough, and often the sand washes away. Amenities: parking (no fee); showers; toilets. Best for: surfing; swimming.

A pavilion welcomes visitors to this 7-acre county beach park fronting the rugged shore in North Kohala. This is a popular local spot for picnics, fishing, and surfing. You're likely to spot some sea life from shore as well. It's a nice rest stop on your way to Pololu Valley. Enjoy the scenery, but don't try to swim here—the water is very rough. Be careful on the hairpin curve going down.

One of the state park system's newest treasures, Kiholo Bay is still in the planning stage, so facilities are sparse (portable toilets, for example) and not yet complete. The brilliant turquoise waters of this stunning bay, set against stark black lava fields, are a cooling invitation on a warm Kohala day. The shore is rocky and the water's a bit cold and hazy due to freshwater springs, but tons of green sea turtles are in residence year-round. Swimming and snorkeling are excellent when the tide is calm. Thanks to the eruptions of Mauna Loa, what was once the site of King Kamehameha's gigantic fishpond is now several freshwater ponds encircling the bay, with a lava-rock island in the middle. Bring plenty of drinking water. Gates are locked promptly at the times indicated; weekend camping is allowed with fee and permit. Community group Hui Aloha Kiholo helps the state manage the park. Amenities: parking (no fee); toilets. Best for: snorkeling; swimming; walking.

A statue of Kamehameha the Great, the famous king who united the Hawaiian Islands in the early 19th century, stands watch over his descendants in North Kohala. The 8½-foot-tall figure wears the king's sacred feather kihei, mahiole, and kaei (cape, helmet, and sash). This is actually the original of the statue fronting the Judiciary Building on King Street in Honolulu. Cast in Florence in 1880, it was lost at sea. A replica was commissioned and shipped to Honolulu, but the original statue was later found in a Falklands Island junkyard. It now stands in front of the old Kohala Courthouse in Kapaau, next to the highway on the way toward Pololu Valley. Every year on King Kamehameha Day (June 11), Kohala residents honor their most famous son with a celebration that involves a parade and draping the statue in dozens of handmade floral lei.

At this family-owned business, the commitment to growing 100% organic coffee starts even before the plants are in the ground, with organic mulch and naturally developed fertilizers that they also sell throughout Hawaii. No pesticides or commercial fertilizers are used on the 80-acre farm. Because it's such an exacting process, only 2% of Kona coffee can claim to be 100% certified organic. They process coffee from cherry to roasted on a solar-powered mill. The farm does private tours (with tastings) by appointment only and even offers a guesthouse should you wish to stay a little longer than a day.  The property can be accessed only by four-wheel-drive vehicles.

In 1819, an estimated 300 Hawaiians were killed on this vast lava field; their burial mounds are still visible at the south end of Alii Drive (called the "End of the World" by locals). After the death of his father, King Kamehameha, the newly crowned King Liholiho ate at a table with women, breaking the ancient kapu (taboo) system. Chief Kekuaokalani, his cousin and co-heir, held radically different views about religious traditions and unsuccessfully challenged Liholiho's forces in battle here. It's a great place to watch the surf, especially when a large swell is in, creating splashes as large as three-story buildings.

Towering coconut trees provide some shade and lend a touch of tropical beauty to this pretty little beach park, which may well be the Big Island's most intriguing stretch of sand. A migratory beach of sorts, it can disappear when strong surf washes away the small white-sand parcel (hence the name "Magic Sands"). Then suddenly, all the sand can reappear within days. You'll know you've found it when you see the body and board surfers. It's often quite crowded, no matter what time of year. Large shore breaks here can be dangerous, so always listen to lifeguard instruction. Amenities: lifeguards; parking (no fee); showers; toilets. Best for: sunset; surfing.

A self-guided, 1-mile walking tour leads through the ruins of the once-prosperous fishing village of Koaie, which dates as far back as the 15th century. Displays illustrate early Hawaiian fishing and farming techniques, salt gathering, games, and legends. Because the shoreline near the state park is an officially designated Marine Life Conservation District (and part of the site itself is considered sacred), swimming is not allowed nor are swim gear or sunscreen. Portable restrooms are available but not drinking water. Gates close promptly at 4 pm, and they mean business!

Here the surf pounds the jagged black rocks at the base of a stunning point, lending a savage beauty to the place. But be advised: this is not a safe place for swimming, so bring only cameras and picnics, not swimsuits. Still vivid in the minds of longtime area residents is the 1946 tragedy in which 21 schoolchildren and three teachers were swept out to sea by a tsunami, back in the days when there was no early warning system.

Tree molds that rise like blackened smokestacks formed here in 1790, when a lava flow swept through the ohia forest. Some reach as high as 12 feet. A meandering trail provides close-up looks at some of Hawaii's tropical plants and trees, and there are restrooms and a couple of picnic pavilions and tables. Mosquitoes live here in abundance, so be prepared.

Designed to honor Hawaii's first Japanese immigrants and named after Hawaii's last reigning monarch, Liliuokalani Gardens' 30 acres of fish-filled ponds, stone lanterns, half-moon bridges, elegant pagodas, and a ceremonial teahouse make it a favorite Sunday destination, or any day of the week for that matter. You'll see weddings, picnics, and family gatherings as you stroll. The surrounding area, once a busy residential neighborhood on Waiakea Peninsula, was destroyed by a devastating 1960 tsunami that killed 61 people.

This park was one of the few coastal parks in the Lower Puna region spared in the 2018 Kilauea eruption. A breezy ironwood grove overlooks rocky shoreline cliffs and offers a pavilion, picnic tables, and restrooms—but no drinking water. The park is significant for the restored section of the old King's Trail system, which circled the coast in the pre-contact era. In those days, regional chiefs used the trails to connect coastal villages and for the transportation of food and materials. Views take in the rugged coast, rocky beach, and coastal dry forest. There's good shore fishing here, so you might see some locals with a line or two in the water.

Snorkelers and divers often make exciting discoveries in the clear waters of this park, now a swimming hole and an underwater museum of sorts. Amazingly, it's also home to a dormant, submerged shield volcano of the same name with a summit of 9,500 feet, showcasing just how deep it gets right offshore. Long ago, when sugar was the economic staple of Kohala, this harbor was busy with boats waiting to make overseas shipments. Now remnants of shipping machinery, train wheels and parts, and what looks like an old boat are easily visible in the clear water. There's no actual beach here, but a ladder off the old dock makes getting in the water easy. Venture out only on tranquil days, though, when the water is calm; conditions can get windy and the ocean choppy.

A popular place with locals, Mahukona is busy on weekends. A camping area on the south side of the park has picnic tables and an old covered pavilion. A trail also leads to nearby Lapakahi State Park, about a ½-mile hike. Amenities: showers; toilets. Best for: snorkeling; swimming.

Located near the subdivision of Ocean View, this lowland forest reserve spreads across several relatively recent lava flows, offering a semi-rugged trail that follows a 2-mile loop past a pit crater and winding around interesting trees such as hau and kukui (candlenut). You can wander through the well-maintained arboretum, snap photos of the eerie forest, and let the kids scramble around trees so large they can't get their arms around them. The pathways can get muddy and rough, so bring appropriate shoes if you plan to hike. Large populations of the Hawaiian hoary bat inhabit the area, which, in totality, encompasses 25,000 acres of forest reserve. Restrooms and picnic areas are available.

Acres of macadamia nut trees lead to a giant roasting facility and processing plant with viewing windows and self-guided tours. You can even watch demonstrations showing how they coat nuts and shortbread cookies with milk chocolate to create their famous products. There are free samples and plenty of gift boxes with mac nuts in every conceivable form of presentation for sale in the visitor center. Children can burn off extra energy on a nature trail here after enjoying dairy-free ice cream for sale.

Also known as Coconut Island, this small island sits just offshore from Liliuokalani Gardens and is a nicely manicured spot where children play in the tide pools and anglers try their luck. Accessible via a footbridge, it was considered a place of healing and refuge in ancient times. There's a grassy picnic area, swimming spots, and a restroom, plus incredible views.

This is a great place to learn about the stunning Papahanaumokuakea Marine National Monument, which encompasses nearly 140,000 square miles in the northwestern Hawaiian Islands and is the only mixed UNESCO World Heritage site (meaning one that has both natural and cultural significance) in the United States. Giant murals, 3D maps, and hands-on interactive kiosks depict the monument's extensive wildlife, including millions of birds and more than 7,000 marine species, many of which are found only in the Hawaiian archipelago. Knowledgeable staff and volunteers are on hand to answer questions. A 3,500-gallon aquarium and short films give insight into the unique features of the monument, as well as threats to its survival. Located in the refurbished F. Koehnen Building, the center is worth a stop just to get an up-close look at its huge stuffed albatross with wings outstretched or the monk seal exhibit.

Dating from as early as AD 480, this parallelogram-shaped structure is a stunning example of a luakiniheiau, used for ritualized human sacrifice to the Hawaiian war god Ku. The isolated National Historic Landmark within Kohala Historical Sites State Monument is so impressive in size and atmosphere that it's guaranteed to give you what locals call "chicken skin" (goose bumps). The place feels haunted, and even more so if you are the only visitor and the skies are dark and foreboding. Visit with utmost care and respect. Nearby is Kapakai Royal Housing Complex, the birthplace of Kamehameha the Great. Although it is now under the care of the National Park Service, family descendants still watch over the site.  Don't drive out here if it's been raining; even with a four-wheel drive, you could easily get stuck.

This coffee producer offers hourly "bean-to-cup" tours, including a tasting and access to the processing plant, which shows dry milling, sizing, coloring, sorting, and roasting. For $10, take the lava tube/nature walk in the cloud forest ecosystem. There's a small retail store where you can purchase coffee and souvenirs. Remember that afternoon rains are common at this elevation, so bring an umbrella and sturdy shoes.

These two huge, oblong stones in front of the Hilo Public Library are legendary: the Pinao stone is purportedly an entrance pillar of an ancient temple built near the Wailuku River. King Kamehameha I is said to have moved the 5,000-pound Naha stone when he was still in his teens. Legend decreed that he who did so would become king of all the islands.

Hugging the long shoreline adjacent to the runway that served Kona's airport until 1970, this beach is flat, generally clean, and speckled with black rocks and coral bits. Mostly calm waters make for good snorkeling, and a few accessible small coves of white sand offer safe water entry and tide pools for children. Shady areas are good for picnics or admiring the Kona skyline, complete with a whale (in season) and a cruise ship or two. A well-tended community garden, jogging trail, and dog park opposite the runway are worth checking out. Just north, an offshore surf break known as Old A's is popular with local surfers. It's usually not crowded, but this area can get busy on weekends. Amenities: parking (no fee); showers; toilets. Best for: sunset; walking.

Shallow, rock-wall-enclosed tide pools and an adjacent grassy picnic area make this park a favorite among Hilo families with small children. The protected pools are great places to look for Hawaiian marine life like crabs and opihi (limpets). There isn't much white sand, but access to the water is easy. The water is usually rough beyond the line of large boulders protecting the inner tide pools, so be careful if the surf is high. This beach gets crowded on weekends. Amenities: lifeguards (weekends, holidays, and summer only); parking (no fee); restrooms; showers. Best for: swimming.

Those tired of the same old white- or black-sand beaches can lace up good hiking shoes or sneakers to get to this olive-green crescent, one of the most unusual beaches on the island. It lies at the base of Puu O Mahana, at Mahana Bay, where a cinder cone formed during an early eruption of Mauna Loa. The greenish tint is caused by an accumulation of olivine crystals that form in volcanic eruptions. The dry, barren landscape is totally surreal but stunning, as aquamarine waters lap on green sand against reddish cliffs. Drive down to South Point; at the end of the 12-mile paved road, take the road to the left and park at the end. To reach the beach, follow the 2¼-mile coastal trail, which ends in a steep and dangerous descent down the cliffside on an unimproved trail. The hike takes about two hours each way and can get hot and windy, so bring lots of drinking water. Four-wheel-drive vehicles are no longer permitted on the trail. The surf is often rough and swimming can be hazardous due to strong currents, so caution is advised. Amenities: none. Best for: solitude; walking.

At the tip of North Kohala, this is one of the Big Island's most scenic beaches. Rain and erosion over millennia have created a stunning, deep-cut windward valley with a windswept gray-sand beach that is piled with large, round boulders and driftwood and backed by ironwood trees and sheer green cliffs. The trail is steep and rocky; it can also be muddy and slippery, so use caution. A Pololu Trail Steward program stations local “stewards” at the trailhead to share historical and cultural perspectives of the valley. Please visit with respect for the land and for all area residents. This is not a safe swimming beach even though locals swim, body board, and surf here. Rip currents and usually rough surf pose a real hazard. Because this is an isolated area far from emergency help, extreme caution is advised. Amenities: none. Best for: solitude.

After a hard rain, these impressive falls thunder into the Wailuku River gorge, often creating magical rainbows in the mist. Rainbow Falls, sometimes known as the Hilo Town Falls, are located just above downtown Hilo at Wailuku River State Park. Take Waianuenue Avenue west for a mile; when the road forks, stay right and look for the Hawaiian warrior marker sign. The falls remain open during daylight. If you're visiting the falls, drive up to Boiling Pots, also inside the park but a bit farther up the road. At Boiling Pots, four streams fall into turbulent pools that resemble cauldrons.

Safe swimming, proximity to downtown Hilo, and the Ice Pond—a freshwater-fed swimming hole that flows into the backwaters of Hilo Bay—are the enticements of this cove. No, there really isn't ice in the swimming hole; it just feels that way on a hot, sultry day. The large pond, between SCP Hilo Hotel and the Ponds Hilo Restaurant, is a favorite of local kids, who enjoy jumping into and frolicking in the fresh- and saltwater mix. The water is usually calm. Amenities: parking (no fee); showers. Best for: swimming.

Just east of Hilo, almost at the end of the road, is one of the best snorkeling sites on this side of the island, as rocky outcrops provide shelter for schools of reef fish and sea turtles. Richardson Ocean Park is also the only beach in Hilo with black and green sand. Don't get close to turtles or disturb them; they are protected from harassment by federal and state law. The shaded grassy areas are great for picnics. The surrounding area unfolds into bays, protected inlets, fishponds, and lagoons, as well as the adjacent Leleiwi Beach Park. Local kids use the small black-sand beach for body boarding. The annual Richardson Rough Water Swim event takes place in October. Amenities: lifeguards (weekends, holidays, and summer only); parking (no fee); showers; toilets. Best for: snorkeling; walking.

Come here to learn how growers create the perfect cup of Kona coffee through a multilayered process, with coffee cherries getting pulped, sorted, and dried in preparation for roasting, both by hand and with machinery. Take an easy, self-guided tour of this mill by following the descriptive plaques around the property. Then stop off at the coffee center to see coffee-making relics, peruse the gift shop, and watch an informational film. Visitors can also enjoy the beautiful views and stroll through a real lava tube on the grounds.
