Hilo
When Kilauea is actively erupting, the only way to see rivers of lava and a lava lake from above is by helicopter — the experience of watching fluid earth from 500 feet defies language. But Kilauea's eruptions are episodic and can cease overnight with no warning; check nps.gov/havo eruption status the morning you intend to book. If the summit caldera is active, book immediately for early in your stay rather than saving it for the last day. Blue Hawaiian has the best narration and safety record on the island; Safari Helicopters is a solid budget option.
Book with Blue Hawaiian Helicopters or Safari Helicopters at Hilo Airport. From $280–450/person. Check current lava activity at nps.gov/havo before booking — if no eruption is active, a volcano ground visit is the better experience and the helicopter is not worth the cost.
Cancelled in cloud ceiling below 1,500ft. Check eruption status — if inactive, ground visits are the only option.
