The Ultimate Guide to Hawaiʻi Volcanoes National Park
Discover the breathtaking landscapes, volcanic wonders, and unforgettable experiences that make Hawaiʻi Volcanoes National Park one of the top natural destinations in the United States.
Hawaiʻi Volcanoes National Park, nestled on the southeastern side of Hawaiʻi Island (the Big Island), is a stunning landscape of extremes—from lush rainforests and high-altitude deserts to fields of solidified lava and two of the world’s most mesmerizing active volcanoes: Kīlauea and Mauna Loa. Spanning more than 354,000 acres, the park offers visitors an ever-changing terrain shaped by centuries of volcanic activity and Hawaiian culture.
In this comprehensive guide, you’ll find information on the park’s top trails, key attractions, cultural gems, practical tips for your visit, and answers to frequently asked questions designed to help both first-time explorers and return adventurers make the most of their trip.
Why Visit Hawaiʻi Volcanoes National Park?
- Home to Two Legendary Volcanoes: Kīlauea, one of the world’s most active volcanoes, and Mauna Loa, the largest active volcano on Earth.
- A Landscape of Extremes: From snowy volcanic peaks to tropical rainforests and arid lava plains.
- Diverse Wildlife and Flora: Spot native birds such as the scarlet ʻiʻiwi and rare plants like the ʻōhiʻa lehua tree.
- Rich Hawaiian Heritage: Discover ancient petroglyphs and stories deeply rooted in island traditions.
- Geological Marvels: Witness lava tubes, craters, cinder cones, and the evolution of land in real time.
How Much Time Should You Spend in the Park?
Given its vastness and the variety of attractions, plan to dedicate at least one full day to exploring Hawaiʻi Volcanoes National Park. Two or more days are ideal if you wish to explore both the main park and more remote sections like the Kahuku Unit. The park is open 24 hours, making it accessible for early sunrise hikes or late-night stargazing under near-pristine skies.
The park staff recommend arriving early—by sunrise—for a chance to enjoy popular trails and overlooks before the crowds. Dusk is equally magical, offering cooler temperatures and exceptional star-watching opportunities due to minimal light pollution.
- Day 1 Highlights: Explore Kīlauea Caldera, hike on crater trails, visit Nāhuku (Thurston Lava Tube), and drive the scenic Chain of Craters Road.
- Day 2 (Optional): Venture to the quieter Kahuku Unit for off-the-beaten-path hiking and panoramic pasture views. Or, take on a longer backcountry trek on Mauna Loa.
- Nearby Village: Before or after your visit, relax in Volcano Village—a hub for art, local eateries, food trucks, and boutique shops.
Top Things to Do at Hawaiʻi Volcanoes National Park
Kīlauea Iki Trail
The 4-mile round-trip Kīlauea Iki Trail is one of the park’s most popular hikes. You’ll descend from a vibrant rainforest thick with native ʻōhiʻa and hapuʻu tree ferns, pass through switchbacks teeming with native birdlife, and emerge onto the crater floor—a vast, otherworldly moonscape formed by the monumental 1959 eruption. Highlights include:
- Spectacular Views: Overlooks reveal the bowl-shaped crater where a world-record 1,900-foot lava fountain once soared.
- Flora and Fauna: Keep an eye out for honeycreepers and the unique ways plants reclaim hardened lava plains.
- Contrasting Landscapes: Experience the sharp shift from rainforest canopies to the stark crater surface.
Nāhuku (Thurston Lava Tube)
The Nāhuku Lava Tube is a 500-year-old tunnel formed by a surging river of 2,000°F molten lava. This accessible cave boasts a flat rocky floor and arched ceilings over 20 feet high in places. A stroll through Nāhuku takes about 20 minutes, with electric lighting to guide you—though a flashlight is handy if you want to explore darker corners.
- Lush Surroundings: The tube is situated within lively rainforest habitats full of native birds and endemic plants.
- Cultural Context: The area surrounding Nāhuku is rich with stories of the land’s volcanic origins and the people who lived here.
Chain of Craters Road
Chain of Craters Road offers an 18.8-mile drive through the volcanic heart of the park down to the ocean’s edge. This scenic journey reveals a diverse sequence of volcanic features and sweeping views.
- Highlights Along the Way: Visit Lua Manu and Pauahi craters, Mauna Ulu lava flows, Puʻu Loa Petroglyphs (dating from 1200–1450), and the dramatic Kealakomo Overlook.
- Geological Showcase: Observe lava tree molds, eruption fissures, cinder cones, and multiple types of lava flow.
- Puʻu Loa Petroglyphs: A short hike here leads to thousands of ancient motifs carved into the hard lava, connecting you with the spiritual legacy of Native Hawaiians.
Kahuku Unit
Located about an hour from the main entrance, the Kahuku Unit covers 116,000 acres of former ranchland on Mauna Loa’s southern slopes. It’s open to the public five days a week and offers:
- Rugged Trails: Hike to the top of old cinder cones, wander through pristine rainforest, or bike across scenic pastures.
- Fewer Crowds: Experience solitude and less-traveled routes than in the main section of the park.
- Education Programs: Kahuku frequently hosts ranger-led activities on the region’s natural and cultural history.
Backcountry Camping and Treks
Serious adventurers can immerse themselves further with an overnight backcountry camping experience—by permit only. Long-distance trails, such as those ascending Mauna Loa, wind through remote volcanic landscapes and offer unparalleled peace—perfect for seasoned hikers seeking a true wilderness challenge.
- Permits: Required for overnight treks, easily obtainable via the National Park Service website.
- Wildlife: Witness the subtle beauty of native flora, birds, and even insects adapted to the volcanic terrain.
- Safety: Preparation for rapidly changing weather and rugged conditions is essential.
What’s Changed Since the 2018 Kīlauea Eruption?
The 2018 eruption of Kīlauea disrupted life both inside and outside the park. Significant ash plumes and earthquakes led to the partial collapse of Kīlauea Caldera, drastically altering the landscape and closing portions of Crater Rim Drive, the Jaggar Museum, and several popular trails. Recovery efforts have reopened many areas, but some closures remain—including popular trails along caldera floors and visitor lookout points.
Before you visit, check the National Park’s official website for up-to-date information on any closures or safety advisories. Despite these changes, the park is as vibrant as ever, with ever-emerging geological marvels and open areas ready to explore.
Learn and Explore: Ranger Tours and FHVNP
The best way to enrich your understanding of the park’s treasures is to join a guided program. The Friends of Hawaiʻi Volcanoes National Park (FHVNP) offers field seminars and private tours led by expert botanists, geologists, and cultural practitioners. Whether you’re curious about volcanic processes, endemic species, or traditional Hawaiian stewardship, these guides help deepen your appreciation of the park’s living science and stories.
