Four men who set off on a day hike to Kokee on Friday were airlifted from the Poomau Canyon Lookout Trail this morning, Kauai County officials said.

The men — two are 18 years old and two are 20 years old —  were reported missing by one of their parents Saturday afternoon when they failed to return home and could not be reached.

Kauai police found their vehicle near mile marker 9 on Kokee Road and called Kauai firefighters and the state Department of Land and Natural Resources for a ground and air search.

Rescue specialists aboard the fire department’s Air 1 helicopter located all four men at about 7 p.m. Saturday night but could not remove them because of darkness, county officials said.

Rescuers dropped water, food and blankets and told the group they would return at daylight this morning.

The men were taken uninjured to the Waimea Canyon Lookout landing zone.
