At just over 4,000 feet Kilauea is not the world's biggest volcano, but it is the most active, having been constantly erupting since 1983. Daily, Kilauea deposits tons of molten lava and is giving scientists real insight into the formation of other volcanoes and the planet. Viewing Kilauea is safe as long as you follow the guidelines given by the Visitor Centre (see 'viewing lava'). For more information contact Hawaiian Holidays.

Volcanoes National Park Kilauea As a rule of thumb ensure that you do not view ahead of the lava flow - advancing lava sometimes ignites pockets of methane gas as it travels. Additionally, do not get too close to the trail. Lava trails at the surface may be much wider beneath the ground, where the lava also flows, and could collapse inwards.
