The air quality here in Volcano Hawaii is generally better than locations southwest of us like Kona and Pahala because of the direction of the Trade Winds. Many travelers visit Hawaii Volcanos National Park to experience active lava flows, however, volcanic eruptions can cause high levels of Sulfur Dioxide and other airborne contaminants. We suggest that you stay informed about current volcanic activity and related air quality. Take safety precautions to limit your exposure to any noxious gases when visiting the park. The best adventure is a safe one!
