Kauai Fire Department officials say a 65-year-old visitor from North Carolina died after collapsing atop a small mountain he climbed over the weekend.
The man hiked Mt. Nonou with his son and daughter-in-law on Sunday.
He sat down at a picnic table after reaching the top of the 1,200 foot peak. He collapsed when he got up to take a picture.
Authorities didn't release the man's name or hometown.
The department said Monday the man's son administered cardiopulmonary resuscitation. The daughter-in-law ran down the trail to call for help.
Firefighters responded by helicopter and by climbing the mountain. The man was taken to Wilcox Hospital, where he was pronounced dead.
An autopsy is being conducted to determine the cause of death.
