Honolulu firefighters responded to a brush fire near Alan Davis Beach on Saturday.

Helicopter crews, police and 12 firefighter units responded to the call that came in around 3:55 p.m.

Due to muddy off road conditions, crews were unable to access the fire with fire trucks.

“Personnel hiked in and initiated a ground fire attack in coordination with water drops from Air 1,” Fire Capt. Scot Seguirant said in a press release. “The Honolulu Police Department assisted with stopping beach goers from entering the burn area while they hiked to the beach from the lighthouse parking lot.”

The fire was contained at 6:11 p.m.

Seguirant said a total of four acres were burned and no structures were threatened by the fire. No injuries were reported.
