18 Best Sights in Hilo, Big Island

Billed as "the only natural tropical rain forest zoo in the United States," this 12-acre county zoo features native Hawaiian species such as the nene goose and the io (hawk), as well as many other rare birds such as the highly endangered Hawaiian crow, or alala. Two Bengal tigers are also part of the collection. The white-faced whistling tree ducks are a highlight, along with monkeys, sloths, and lemurs. There's also a petting zoo on Saturdays from 1:30 to 2:30. Myriad species of lush, unusual tropical plants fill the grounds. To get here, turn left on Mamaki off Highway 11; it's just past the "Kulani 19, Stainback Hwy." sign.

Four separate streams fall into a series of circular pools here, fed by Peepee Falls just above, and the resulting turbulent action—best seen after a good rain—has earned this scenic stretch of the Wailuku River the nickname Boiling Pots. Swimming is not allowed at Boiling Pots or anywhere in the Wailuku River, due to extremely dangerous currents and undertows. The falls are 3 miles northwest of downtown Hilo off Waianuenue Avenue; keep to the right when the road splits and look for the sign. The gate opens at 7 am and closes at 6 pm. You may want to combine a drive to this site with a visit to Rainbow Falls, a bit closer to downtown.  You may be tempted, as you watch others ignore the signs and climb over guardrails, to jump in, but resist. Swimming is prohibited and unsafe, and people have died here.

Constructed in 1859 by New England missionaries, this church is known for its services in Hawaiian and for the choir, which sings hymns in Hawaiian. In 1902, Hawaiian musical legends Harry K. Naope Sr. and Albert Nahalea Sr. began the choral traditions still practiced by their descendants. The church, with its iconic yellow spire, has an interesting history that dates to 1824 when it was a thatched structure.

With all the buzz about Kona coffee, it's easy to forget that estate-grown coffee is produced throughout the rest of the island; the Hilo Coffee Mill, on 24 acres in lush Mountain View, is a pleasant reminder of that. In addition to farming its own coffee on-site, the mill has partnered with several small coffee farmers in East Hawaii in an effort to put the region on the world's coffee map. You can sample the company's efforts, tour the mill, and watch the roasters in action. They host a farmers' market every Saturday from 9 to 2.

One of the most consistent places on the east side to catch a wave, Honolii is popular with the local surf crowd. The beach is a mix of black sand, coral, and sea glass, with plenty of rocks. A shady grassy area is great for picnics while you watch the surfers. Note that the presence of surfers is not an indication that an area is safe for swimmers; winter surf is very rough. A pond just to the north is good for swimming, but it's deep and there is a drop-off. There's limited parking on the narrow roadside. Walk down the stairs and veer left over the rocks. Amenities: lifeguards; toilets. Best for: surfing.

A bronze statue in this park, the central town square for more than a century, depicts King David Kalakaua (1836–1891), who revived the hula and is the inspiration for Hilo's Merrie Monarch Festival. Erected in 1988, the statue depicts the king with a taro leaf in his left hand to signify the Hawaiian people's bond with the land. The park is surrounded by civic buildings and a war memorial. There is a huge, spreading banyan tree and small fishponds but no picnic or recreation facilities. According to local tradition, families of military personnel often leave leftover floral displays and funeral wreaths along the fishpond walkway as a way of honoring their loved ones.

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.

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.

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.

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.

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.

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.

At the Wailoa River State Recreation Area, a beautiful park setting near downtown Hilo, this circular exhibition center hosts monthly exhibits in two galleries featuring impressive work from local artists. Pieces range from photography, pottery, contemporary painting, quilts, glassworks, multimedia, and woodworking to musical instruments and artwork depicting Hawaii's native species. There's also an educational space for workshops and community events.
