Warm Vapor emerges at low-temperature geothermal conditions near Nanawale Estates at just 422 feet elevation. The designation as warm water rather than steam reflects subtle geothermal heating in this marginal geothermal zone on the Big Island.

The setting is accessible via short walk from Noni Farms Road in relatively flat terrain. Vegetation and modest elevation suggest semi-developed surroundings where geothermal activity remains subtle, with heated gases or water vapor escaping without the dramatic steam emissions found at major fumaroles.

History of Warm Vapor

This warm geothermal manifestation reflects Kilauea's heat influence extending beyond major vent zones. Low-temperature geothermal activity indicates groundwater circulation at depths sufficient for modest heating even in areas distant from primary volcanic features.

The site lies just 273.7 meters from Noni Farms Road via short walk. Public access appears straightforward, though the spring's low profile means facilities are minimal. Visit during daylight hours on established trails.
