10 Best Family Things to Do on Hawaii Big Island

Families will enjoy the thrill of ziplining at Kohala Canopy Adventure. Active and adventurous types of all ages should love the combination of 9 lines, 5 sky bridges, and a rappel within a forested nature reserve. The action kicks off with an offroad transfer to the summit station in a Pinzgauer truck, an open-air, all-terrain vehicle originally designed for the Swiss military.

Tree-to-tree zipping takes the hard work out of moving between lines. After a couple of practice runs, even beginners should be able to appreciate the scenic views as they traverse the canopy at speeds of up to 45 mph.

At Sulphur Banks, locally known as Ha'akulamanu, volcanic gases seep from the ground – a tangible reminder of the area’s tectonic activity. Those gases comprise carbon dioxide, sulphur dioxide and hydrogen sulphide, and it’s thanks to the latter that the gas smells like rotten eggs. Sulphur gases deposit crystals and others form sulphuric acid, which acts on the lava to form an iron oxide (that's rust to you and me) riddled clay.

Reaching Sulphur Banks takes an easy stroll along the mile-long trail from the parking lot. However, it’s not recommended for very young children as it can cause respiratory problems and aggravate conditions such as asthma. Instead, take them to nearby Steam Vents or Steaming Bluff, where the hot volcanic rocks underground superheat the groundwater and send it to the surface as billowing clouds of steam.

A visit to Laupahoehoe Train Museum can ignite kids’ interest, even though railways won’t be the first thing that springs to mind when you think about Hawaii. The 1875 Reciprocity Treaty between the USA and the Hawaiian Islands led to a boom in sugar for export. Infrastructural improvements were required to facilitate that trade and the Hawaii Consolidated Railway was one of them.

Though the Hilo Railroad was initially a success, extensions through the challenging island terrain were costly. Damage from a tsunami in 1946 was the final nail in the railroad’s coffin. Today, the museum tells the story of this fascinating line and the tragedy of the natural disaster that finished it off. You can find the museum in the old station agent’s house, while out back on what’s known as the wye, visitors can see a replica standard gauge caboose, which would have seen service bringing up the rear of a freight train.

Views from the window during a Blue Hawaiian Helicopters ride are jaw-dropping as Hawaii’s majestic landscape is as impressive from the air as it is on the ground. The company runs a range of tours, ranging from a 15-minute taster ride to the Big Island Spectacular flight package.

Black-sand beaches and dense, emerald-green rainforests form the phenomenal pre-show to the main act: Kilauea. This volcano is among the most active on the planet and erupted almost continually from 1983 to 2018. A landing at Laupahoehoe Nui on the Kohala Coast to see a breathtaking 1,200-ft-tall waterfall adds an extra dimension to this family-friendly bucket lister.

Kahua Ranch describes itself as a working ranch that welcomes visitors, offering many activities that are also family-friendly. Don helmets and safety goggles to enjoy the adrenaline rush of an ATV adventure across lush Hawaiian terrain. Full instruction is given; those not wishing to ride solo and children aged between 8 and 15 years can ride behind a guide.

For something a little more traditional but no less fun, horseriding excursions depart from Na’alapa stables on the ranch. In the company of paniolos – Hawaiian cowboys – riders cross verdant pastures grazed by sheep and cattle. Panoramic views of the mountainous scenery, cinder cones and Hawaii’s dramatic coastline distract the saddle-sore. Tours are pre-booked only.

At the Imiloa Astronomy Center, you can embark on an immersive journey that takes you to the stars via Hawaii’s unique culture. Imiloa translates as “to explore, driven by a sense of wonder and imagination”. There’s much to learn about the parallels between Hawaiian beliefs and the world of science.

In the 120-seat planetarium, the film Mauna Kea: Between Earth & Sky both educates and entertains. Follow the legend of the battle between goddesses Pele and Poli'ahu that led to the creation of the Hawaiian Islands. Gaze at the night sky with its dazzling stars, galaxies and nebulae, before paying a virtual visit to the observatory on top of the dormant volcano Mauna Kea.

At the Pacific Tsunami Museum, visitors learn that such natural events are a fact of life if you live in Hawaii. It took the horrifying events of the 2004 Indian Ocean tsunami for many to realize just how deadly such natural disasters could be. The Pacific Tsunami Warning Center is well practiced in warning islanders of impending threats. Visitors to the museum will learn just how important that knowledge is to Big Island.

The town of Hilo has suffered more damage and loss of life from tsunamis than anywhere else in Hawaii, most notably in 1946 and 1960. Through a mixture of text-based exhibits, photographs, and videos, the museum explains what it’s like during an event of a tsunami and how to stay safe when it occurs.

Ocean Rider Seahorse Farm at Keahole Point, Kona, is one place on Hawaii’s Big Island where you’ll find pregnant males. Seahorses are part of the syngnathid family, the only species where it’s the male who gets pregnant, fertilizing the female’s eggs and carrying them in a pouch until they hatch.

The team at Ocean Rider looks after over 30 species of seahorses and seadragons at their oceanfront farm. Children aged 5 years and over will have the opportunity to feed and hold a seahorse as well as learn interesting facts about these curious creatures. Tours also touch on the topics of marine conservation and sustainability.

Thurston Lava Tube, also known as Nāhuku, is a remarkable landform that was created by a massive flow of red hot lava. When it was discovered in 1913, there would have been lava drippings hanging from the roof of this subterranean tunnel. They looked a little like stalactites, though souvenir hunters soon stripped them out. Family adventurers can reach the site half a mile from the parking lot, past tree ferns and o’hia trees.

Today, the cave can become busy. Lit between 8 am and 8 pm, access is possible outside these hours. The intrepid can strap on a head torch and venture into the lava tube in the dark. The reward for the fearless is the chance to experience such a splendid place without the crowds.

Abundant marine life makes Kahaluʻu Bay a popular choice for snorkelers enjoying Big Island. Some describe getting into the water here as akin to swimming in an aquarium, thanks to the variety of species. Sea turtles and sea urchins swim alongside the exotically named Bullethead Parrotfish, Racoon Butterflyfish, Moorish Idol, Orangespine Unicornfish and Hawaiian Spotted Boxfish.

Calm, shallow waters make this the ultimate family destination, but stick to the south side of the beach to avoid getting in the way of the surfers that also frequent this stretch of coastline. Bring a picnic for when you finally decide it’s time to head back to dry land.
