Honolulu firefighters this morning rescued a 73-year-old woman with a head injury from Diamond Head Crater Trail.

The 911 call came in at about 7 a.m. today, according to the Honolulu Fire Department, and five units with 16 personnel responded. The first firefighters to arrive on scene ascended the trail by foot and found the injured woman at the tunnel section at 7:21 a.m.

She had reportedly fainted, according to the 911 caller, and suffered a bad bruise to her head when she fell.

After an initial medical assessment and basic life support treatment, she was packaged into a rescue stretcher and airlifted by the Air 1 helicopter to the Diamond Head Crater landing zone. She was transferred to the care of Emergency Medical Services.

Three others that were hiking with the woman descended the trail on their own, escorted by firefighters.

The rescue this morning follows another from 4:20 p.m. on Wednesday, when a 911 call came in for three lost hikers on the Upper Waimano Trail in Pearl City.

HFD said five units with 12 personnel responded, with the first arriving at 4:35 p.m.

Three women visiting from Florida, two 25-year-olds and one 26-year-old, got lost on their way down from Waimano Falls. They had departed the trail and were following a riverbed when they got lost.

HFD asked them to move to an open area, and eventually found them following an aerial search via Air 1.

The three were airlifted off the trail and taken to the established landing zone off of Waimano Home Road at 6 p.m. They were not in need of any medical attention.

HFD reminds hikers to set a turnaround time and exit a trail well before sunset, to stay on a trail to reduce chances of getting injured or lost, and to learn as much as you can about a trail prior to hiking.
