When Kīlauea is active, viewpoints and trail access change quickly. When it is quiet, classic walks include Kīlauea Iki, Devastation Trail and segments of Crater Rim. Sulfur dioxide, unstable crust and closures are part of planning—not afterthoughts.
Descend into a solidified crater floor and climb back through rainforest—park classic when open.
Short paved and boardwalk stops for first-time visitors and eruption viewing when designated.
Longer wilderness routes only when officially open; carry water, sun protection and a real plan.
Check nps.gov/havo for eruption updates, vog (volcanic air pollution) and trail closures before you drive up. America the Beautiful passes cover entrance. Never ignore barrier tape on lava fields.
Yesterday's open trail may be closed today.
Summit weather is cooler; respiratory-sensitive visitors should watch air-quality guidance.
The park is a longish drive from Kona resorts—start early.
Can I hike on active lava?
Only where the park explicitly allows access. Approaching ocean entries or unstable flow fields on your own is deadly and often illegal.
Is the park open during eruptions?
Often yes with closures of specific areas. Check the official day-of map.
Do I need a guide?
Not for short open trails. Guided trips help for night viewing or longer routes when offered.
Same as Maui volcano hiking?
No. Maui's Haleakalā is a different park and island. This page is Hawaiʻi Island's Hawaii Volcanoes National Park.
The park protects two of the world's most active volcanoes and landscapes sacred in Native Hawaiian culture. Kīlauea and Mauna Loa shape both the science and the visitor experience.
Access is managed by the National Park Service with frequent updates during eruptive episodes.
This page is an independent guide for visitors. It is not affiliated with the National Park Service.
