Lava flow in Hawaii’s Volcanoes National Park
Hardened lava rock from Kilauea, an active volcano on Hawaii’s Big Island, is shown in Volcanoes National Park near Kalapana, Hawaii. The current lava flow erupted from a vent on the volcano in May and made its way to the sea in late July. Visitors can hike about 10 miles round trip to see the lava, or take a boat or helicopter tour to see the flow.
