Honolulu firefighters airlifted two distressed hikers in separate rescues on Koko Crater Trail hike in Hawaii Kai Thursday morning.

At about 6:50 a.m. the Honolulu Fire Department responded to a hiker in distress on the trail with six units and 17 firefighters. The first unit arrived at 7 a.m. and walked up the trail, according to an HFD news release, while the second unit secured a landing zone.

The man in his 60s “fell, sustained an injury and was unable to descend the trail on his own,” HFD officials said.

Firefighters reached the man at 7:11 a.m. and treated his injuries before preparing him for transport. The man was safely airlifted by HFD’s Air 1 helicopter to the landing zone where city Emergency Medical Services paramedics took over at 7:30 a.m., officials said.

At 11:10 a.m., HFD was called back to the trail for an injured male hiker. They responded with six units and 17 personnel.

The hiker in his teens had fallen near the top of the trail and was unable to descend on his own, HFD said. Rescuers hiked up the trail and reached the teen at 11:42 a.m., conducted a medical assessment and performed basic treatment. The hiker was then safely airlifted to the landing zone where medical care was transferred to EMS at 12:05 p.m.

HFD encourages hikers to: “Assess your fitness level and hiking capabilities. Compare your level of fitness, ability, and experience with the trail description. Be practical and realistic. There are a wide variety of trails in Hawaii, so pick one that suits your level. Ensure you stay hydrated to avoid heat exhaustion, becoming disoriented, and muscle cramps,” according to the release.
