The Island of Hawaiʻi, known as the Big Island, is the largest Hawaiian island, with active volcanoes, Mauna Kea and black-sand beaches. It covers about 4,028 square miles (10,430 km²), more than all the other Hawaiian islands combined, and is built from five shield volcanoes, three of them still active, including Kīlauea and Mauna Loa. Mauna Kea, at 13,803 feet (4,207 meters), is the highest point in the state.
Its size creates two very different coasts. The dry, sunny Kona side in the west, around Kailua-Kona and the Kohala Coast resorts of Waikoloa, is where most visitors stay, in condos and vacation homes near lava-rock shores and sandy bays. The green, rainy Hilo side in the east is closer to Hawaiʻi Volcanoes National Park, waterfalls and the island's largest town. Many travelers split their stay between the two, because driving from one side to the other takes around two hours or more.
Kailua-Kona is the most practical base for a first visit: an oceanfront town along Aliʻi Drive with condos, shops, snorkeling at Kahaluʻu Bay and easy access to the main airport. Keauhou, just south, is quieter, and the coffee-growing slopes above town around Holualoa offer cooler air and farm-style homes.
The Kohala Coast, north of the airport, holds the resort areas of Waikoloa and neighboring developments set among black lava fields. Villas and condos here suit families and groups who want pools, golf and calm swimming bays.
On the east side, Hilo is a lived-in harbor town with older homes, gardens and lower prices, good for travelers who come for the volcano and the rainforest rather than the beach. Volcano village, in cool upland forest beside the national park, has cabins and cottages for those who want to see the park at dawn and dusk.
Hawaiʻi Volcanoes National Park, created in 1916 and listed as a UNESCO World Heritage Site in 1987, protects two active volcanoes: Kīlauea, one of the most active on Earth, and much of Mauna Loa. Mauna Loa, the largest shield volcano on Earth, erupted in 2022 after about 40 years of quiet. At Kīlauea's summit, Halemaʻumaʻu crater, long sacred in Hawaiian tradition, has erupted in a long series of lava-fountaining episodes since December 23, 2024, within a closed area of the park.
Crater Rim Drive and its overlooks, the Chain of Craters Road down to the sea cliffs and the walk through Nāhuku, the Thurston Lava Tube, are the classic visits. Volcanic gas, known locally as vog, can affect air quality, so people with breathing or heart conditions should check the park's air-quality alerts. The park is roughly 45 minutes by car from Hilo and around two and a half hours from Kailua-Kona.
Much of the coastline is young lava rock, so beaches tend to be small and varied: white sand on the Kohala Coast, black sand in the south and pocket coves along Kona. Hāpuna Beach State Recreation Area on the Kohala Coast is one of the island's best-known swimming beaches, with lifeguards, though the state warns of rip currents and pounding shore break in high surf.
In Kona, Kahaluʻu Bay is a sheltered snorkeling spot, and Kealakekua Bay to the south combines clear water with deep history. Night snorkeling with manta rays off the Kona coast is a popular guided outing. In the remote Kaʻū district, Punaluʻu is the island's most famous black-sand beach. Surf can rise quickly, especially in winter, so swim where lifeguards are on duty, and never turn your back on the waves.
Mauna Kea's name comes from Mauna a Wākea and is usually translated as white mountain, after the snow that often caps its summit between about October and April. The summit is sacred in Hawaiian tradition and also hosts about a dozen astronomical observatories. The altitude, steep road and changeable weather make summit trips genuinely difficult, so follow official guidance and do not rush up from sea level.
North of Hilo, the Hāmākua Coast runs past deep gulches and old sugar towns. ʻAkaka Falls State Park has a short rainforest loop to a tall waterfall, and the road ends at the Waipiʻo Valley Lookout above a sacred valley once home to Hawaiian royalty. In Hilo itself, Rainbow Falls on the Wailuku River and Liliʻuokalani Park and Gardens on Banyan Drive make easy stops, and the coffee farms of Kona welcome visitors on the other side.
This island is the birthplace of the Hawaiian Kingdom. Kamehameha I rose to power here before uniting the islands, and Puʻukoholā Heiau National Historic Site in Kohala preserves the great temple linked to his rise. In 1779 Captain James Cook anchored in Kealakekua Bay, where he was killed weeks later. Nearby, Puʻuhonua o Hōnaunau National Historical Park protects a traditional place of refuge, where those who broke sacred law could find safety.
In Kailua-Kona, Huliheʻe Palace, built in 1838, was a vacation home for Hawaiian royalty and is now a museum, while Mokuaikaua Church traces its congregation to 1820. Hilo remembers the tsunamis of 1946 and 1960, which devastated its bayfront, at the Pacific Tsunami Museum. Each spring the town hosts the Merrie Monarch Festival, a week-long celebration and competition of hula that begins on Easter Sunday.
The island has two main airports. Ellison Onizuka Kona International Airport at Keāhole (KOA), just north of Kailua-Kona, receives most visitors, with direct flights from the US mainland and inter-island connections. Hilo International Airport (ITO) on the east side is mostly served from Honolulu and is convenient for the national park.
A rental car is essential, because distances are long and public transport is limited. A highway circles the island, and the Saddle Road crosses the high plateau between Mauna Kea and Mauna Loa, linking the two coasts. Kailua-Kona to Waikoloa takes roughly 30 minutes, and Kona to Hilo at least an hour and a half. Fuel up before long drives through Kaʻū and the uplands. The island uses the US dollar and Hawaii-Aleutian Standard Time.
The Big Island holds many climates in one place. Kona and the Kohala Coast are dry and sunny, Hilo receives well over 100 inches (2,500 millimeters) of rain a year, and the volcano summits can be cold, windy or snowy. Pack layers if you plan to visit Volcano village or Mauna Kea. The weather is warm at sea level all year; winter brings more rain to the east and bigger surf, and the Pacific hurricane season runs from June to November.
Vacation rentals are regulated by Hawaiʻi County. Its 2018 ordinance, known as Bill 108, limits unhosted short-term vacation rentals mainly to resort, hotel and certain commercial zones; those already operating in residential and agricultural areas before 2019 may continue only with a nonconforming use certificate renewed each year. A 2025 ordinance requires both hosted and unhosted vacation rentals to register, and a bill to rewrite these rules was still before the County Council in late 2026. Choose a properly registered rental and check the county Planning Department's current rules.
Most visitors stay on the Kona side, in Kailua-Kona or the Kohala Coast resorts such as Waikoloa, for sunshine, beaches and the main airport. Hilo and Volcano village suit travelers focused on the national park, waterfalls and rainforest. With a week or more, many people split their nights between the two sides.
Around two and a half hours by car from Kailua-Kona, depending on the route and stops, and roughly 45 minutes from Hilo. Because of the distance, many visitors from Kona spend a night in Hilo or Volcano village rather than doing the round trip in one day.
Sometimes. Kīlauea has erupted in a series of summit episodes since December 2024, confined to a closed area of the national park, and glow or fountains may be visible from public overlooks during active phases. Activity changes often, so check the USGS Hawaiian Volcano Observatory and the park before you go.
Ellison Onizuka Kona International Airport (KOA) is the main gateway and the closest to Kailua-Kona and the Kohala Coast. Hilo International Airport (ITO) is closer to the volcanoes and the east side. Some travelers arrive at one and leave from the other.
Plan at least five to seven days. The island is large, and a good visit includes beach time on the Kona side, a full day or overnight at Hawaiʻi Volcanoes National Park, and a day along the Hāmākua Coast or up toward Mauna Kea.
Yes. Distances between towns, beaches and parks are long, and public transport is limited. A car lets you combine the Kona coast, the volcano and the waterfalls near Hilo. Check your rental agreement for any limits on roads such as the Mauna Kea summit road.
Yes, especially the Kohala Coast, where resort areas such as Waikoloa have calm bays and pools, and Kona, with easy snorkeling at Kahaluʻu Bay. Children usually enjoy walking through Nāhuku lava tube and seeing waterfalls near Hilo. The high summits are not suitable for young children.
It depends on where you are. The Kona and Kohala coasts are mostly dry and sunny, Hilo is warm but very rainy, and the high volcano summits can be cold and even snowy in winter. Sea-level temperatures stay warm all year.
