Honolulu firefighters rescued a solo hiker who became lost on the Upper Waimano Trail in Pearl City Sunday night.

Firefighters responded to a 911 call of a lost hiker shortly after 7:35 p.m. The woman, 30, had been hiking since 1 p.m. but became lost, the Honolulu Fire Department said.

With 16% of battery life remaining on her cell phone, firefighters were able to locate her via GPS.

The fire department’s Air 1 helicopter attempted to locate her but returned to a landing zone near Pearl City High School due to heavy rainfall.

Four firefighters ascended the trail on foot, located the hiker at about 10:30 p.m. and safely escorted her out of the trail just after 1:10 a.m. today.

The fire department provided the following hiking safety tips:

>> Prior to your hike, inform someone of your hike location and destination.

>> Start your hike early in the day to allow time to return before dusk.

>> In case of an emergency, bring a fully charged cell phone and backup battery.

>> Stay put should you get lost.
