On the Big Island, a tour group had to be rescued from a trail after one of the hikers got injured.
It happened around 5 p.m. Wednesday at Kahaualea Forest Reserve in Hawaii Volcanoes National Park.
Fire officials say the group was attempting to view an active lava flow when a 36-year-old woman sprained her ankle on muddy ground roughly 3.5 miles into a trail.
Because she was unable to walk out, firefighters used a helicopter to pick up all six tour group participants and two guides and take them to safety.
The injured woman was treated at a fire station.
