Hawai`i Volcanoes National Park encompasses two of the world's most active volcanoes: Kilauea and Mauna Loa.  This is a very dynamic natural area with many dangers. Educate yourself as to the hazards. Common sense is not enough. Stay Alert - Stay Alive!

On the Road
Drive courteously and defensively. Use seatbelts and headlights. Watch for pedestrians and bicyclists. Avoid the endangered nene goose.

Trails
STAY ON MARKED TRAILS! Vegetation or cinders may hide deep cracks in the ground. Use caution near cliffs, cracks, and steam vents. The edges of these features are unstable and can be slippery. Keep your children safe. 

Hiking over cracks and holes, loose rock, and thin lava crust greatly increases your risk of getting hurt. Falling on lava may result in severe wounds.

WEAR STURDY SHOES AND LONG LIGHTWEIGHT HIKING PANTS (falling on lava is like falling on broken glass).
CARRY AND DRINK PLENTY OF WATER.
AVOID HIKING AFTER DARK (cracks, cravasses, and cliffs look like shadows - depth is not evident in the dark).

Volcanic Fumes
Fumes (volcanic gasses) are hazardous to everyone's health. Visitors with heart or breathing problems and infants, young children, and pregnant women are especially at risk and should avoid being in areas where fumes persist.

The new eruptive vent in Halema`uma`u Crater, Sulphur Banks, and Pu‘u ‘O‘o vent generate high levels of gasses that may affect visitors - even those visitors who are healthy.

Concentrations of these gasses is often dependent on wind direction. Hawai‘i's normal tradewind pattern generally blows gasses, emitted from the two main vents on Kilauea, away from most visitor areas. However, even on a tradewind day, fumes from Pu‘u ‘O‘o and Halema‘uma‘u may cross a roadway or linger in other areas of the park. In this event, close your car windows and run the air conditioning on recycled air and leave the area. 

There are times when the park will close due to high levels of volcanic gasses. Be flexible - Closures are initiated for visitor and employee safety.

Near the ocean
The park's coastline does not include safe beaches or swimming areas that visitors may drive to. Expect strong winds, steep and unstable sea cliffs, and high waves.

Volcanic Eruptions
Volcanic eruptions can occur at any time and can be extremely hazardous. Even from a distance, gasses and fallout (Pele's hair, pumice, and cinder) can cause lung and eye irritation.
Heed the instruction of park rangers and obey signs on roads and trails.
Never enter closed areas.

Current Eruption
Lava viewing opportunities are constantly changing. Check with rangers in the Kilauea Visitor Center for current activity and safety information.
