Honolulu firefighters this morning rescued a hiker who injured her ankle while climbing the stairs of Koko crater.

The Honolulu Fire Department received a call to 911 at 8:07 a.m. and responded with five units and 16 people.

The 911 caller reported that his friend, a 55-year-old resident, injured her left ankle after walking for about 90 minutes. They were then three quarters of the stairs.

Two firefighters walked up the stairs at 8:33 a.m. and joined the patient about 10 minutes later. The injured woman was packed and airlifted by HFD’s Air 1 helicopter to the Koko Head District Park landing area, where care was transferred to emergency medical services.

Her friend was not injured and walked down the track on her own, escorted by firefighters.

On Wednesday evening, firefighters also rescued a kayaker in distress on Moku Nui Island off Lanikai.

The 911 call arrived at 5:13 p.m. and five units with 16 people responded, the first arriving at the scene nine minutes later.

The kayaker’s male companion reported that the woman, 23, fell ill while paddling to Moku Nui and was unable to make the return trip to Lanikai Beach.

The HFD Air 1 helicopter transported the woman to a landing area at Lanikai Community Park, where she was transferred to emergency medical care at around 6 p.m.

His companion was able to return to shore safely on his own.
