Two teenage hikers were rescued on the Koko Head Crater trail after they became “sick” Saturday morning, the Honolulu Fire Department reported.

At around 11:30 a.m. Saturday, HFD received a call about two teenage girls visiting Hawaii who were on the trail but were unable to descend on their own. They were part of a hiking group that included about 15 other people.

HFD arrived a few minutes later to establish a landing zone for its Air 1 helicopter and begin walking the trail by foot.

At around noon rescue personnel arrived at the girls’ location, conducted a medical assessment and provided basic life support.

The hikers were then flown to a nearby landing zone, and their care was transferred to the Honolulu Emergency Medical Services at around 12:30 p.m.
