Hanalei, Hawaii —  A helicopter crashed Thursday afternoon off a remote beach of the Hawaiian island of Kauai, killing three people and injuring two, authorities said.

The helicopter was carrying a pilot and four passengers when it crashed at Kalalau Beach, the Kauai Fire Department said. The beach is on the Na Pali Coast on Kauai’s north shore. The Coast Guard told CBS News the chopper went down about 100 yards offshore.

Police said three people died and two others were transported to Wilcox Medical Center for treatment.

Officials said the helicopter was operated by Airborne Aviation,

Helicopter tours are a popular way to explore the cliffs, beaches and waterfalls lining the Na Pali Coast, which is otherwise only accessible by hiking or boat.
