Firefighters rescued a 44-year-old visitor who fell and injured her wrist today while hiking the Maunawili Falls Trail.

An off-duty doctor hiking in a separate group witnessed the woman slip and fall forward about 4 feet. She braced herself during the fall and injured her left wrist that resulted in “obvious deformities,” the Honolulu Fire Department reported.

The doctor provided immediate assistance.

HFD received a 911 call at 11:21 a.m., and five rescue units with 16 personnel were dispatched.

The first unit made contact at 11:42 a.m. with the woman, just one-eighth of a mile in from the trailhead.

Firefighters treated the woman and aided her across a streambed to a clear area from which she was airlifted to a landing zone at the Maunawili Neighborhood Park.

Her husband hiked out on his own.

Emergency Medical Services treated her wrist injury and transported her to a hospital in stable condition.

HFD reminds hikers that Hawaii’s forests often have very dense growth, which can mask dangerously steep drop-offs and cause one to become disoriented.

Also, HFD reminds hikers to pick a trail that suits their level of fitness and experience.
