Steam Vent — Not a Soaking Spring

Steam Vents is a steam vent, not a traditional hot spring. These geothermal features can be extremely dangerous — boiling water, toxic gases, and unstable ground are common hazards. Do not attempt to soak.

These high-elevation steam vents rise to 13,426 feet on Mauna Loa's slopes, making them among Hawaii's highest geothermal features. The National Park Service maintains open public access along designated routes.

Location

Hikers approach through Hawai'i Volcanoes National Park's interior, ascending into increasingly alpine terrain where vegetation thins dramatically. At this elevation, temperatures average 63.7°F despite the tropical latitude, and steam vents hiss through rocky ground.

The North Pit Trail provides access just 15 meters away. Visit during stable weather to navigate exposed, barren lava fields safely. Expect thin air and intense sun exposure on this high-altitude hike.

History of Steam Vents

Mauna Loa's shield volcano construction created these fumaroles as groundwater circulates deep within the mountain's flanks, heated by residual magma. Persistent geothermal activity demonstrates active volcanic processes at these extreme elevations.
