The centerpiece of Hawaii Volcanoes National Park is the volcano Kilauea, the world’s longest continuously erupting volcano. The lava has been flowing here since 1983 and there are few places in the world where the destructive and creative process of volcanism is better on display. The hiking trails here are surprisingly varied, taking visitors through lava tube caves, across desolated former lava lakes, into dense rain forests filled with sulphur vents, and down to a beach where new land is literally created right before your very eyes. Hiking here is like no other place on the planet – definitely make the time for a visit if you’re on the Island of Hawaii.
