Hawai‘i Volcanoes National Park

Hawai‘i Volcanoes National Park protects 520 square miles on the southeast side of the Big Island of Hawai‘i. The park is a place of wonder to explore, containing two of the most active Volcanoes on the planet, Mauna Loa and Kīlauea. Mauna Loa is 13,677 feet tall, one of the world’s largest volcanoes – only slightly shorter than Moana Kea, the biggest volcano on the Big Island.

Major volcanic and seismic activity from Kīlauea in the summer of 2018 altered the park’s landscapes, closed roads and trails, and showed just how profound the volcano’s actions could be. A park advisory described the 12-week eruption:

Large lava flows covered land southeast of the park destroying over 700 homes and devastating residential areas in the Puna District. At the same time, the summit area of the park was dramatically changed by tens of thousands of earthquakes, towering ash plumes, and 62 massive collapse explosions. The events caused profound damage to park infrastructure unprecedented in the park’s 102 year history including building damage, rock falls, deep cracks in roads and trails, and numerous breaks to water and sewer lines.

The Halemaʻumaʻu Crater within Kīlauea changed remarkably during the eruption. The crater is 1,600 feet deeper than it was before 2018 (as a reference, the Empire State Building is 1,450 feet tall). The crater grew in volume from about 60 million cubic yards to 1.2 billion cubic yards. The National Park Service has shared incredible before and after photos showing just how much Kīlauea changed.

Because Hawai‘i Volcanoes National Park is such a dynamic place, park conditions may impact your itinereary. Check for updates before your visit and stop by the Kīlauea Visitor Center (next to the park entrance) when you arrive to get current closure information and recommendations.

What to do in Hawai‘i Volcanoes National Park

This is a great park to explore by car and on foot. Kīlauea Caldera is the main attraction, with a Steaming Bluff along its edges and a massive crater to look in upon. Kīlauea is visible from overlooks along Crater Rim Drive (which is no longer open as a full loop) and adjacent hiking trails. Chain of Craters Road descends toward the park’s coast, passing hardened lava flows and craters. The road ends at Hōlei Sea Arch, a thrilling basalt formation. Just up the road, Pu‘u Loa Trail leads to the largest petroglyph field in Hawai‘i.

In the summer of 2018, Hawaiʻi Volcanoes National Park experienced the most dramatic volcanic activity in it's more than century long history. Land considered stable was humbled and demolished. When the earth stopped exploding and when the shaking of 60,000 earthquakes ceased, Crater Rim Drive, the road that ringed Kīlauea, was ruined in many places. Although the north and east sides of...

Filled with bold volcanic features and landscapes reinvented by eruptions, Hawaiʻi Volcanoes National Park might seem an unlikely place to find a deep-rooted forest packed with plant diversity and a thriving bird population. Kīpukapuaulu rises like an oasis, framed the less-fertile lands forged by more recent lava flows. Kīpukapuaulu Trail is a 1.2-mile long nature trail loop with 185... Read more.

Tree Molds Hawaii Volcanoes National Park Lava Tree Molds Hawaii
Trees grow big and strong, but they are outmatched by the forces of lava. A tree's last stand against a lava flow can result in a tree mold - a hole in the surface of hardened lava where a tree once stood. Tree molds provide information about lava flows and preceeeding forests. See tree molds with your own eyes at a spot near the entrance of Hawai‘i Volcanoes National Park. A tree... Read more.
