Two hikers died in separate fall incidents on Mariner’s Ridge this morning and above Kaaawa Saturday.

Paramedics said a 70-year-old man died after falling while hiking the Mariner¹s Ridge Trail at about 9:45 a.m.

The man apparently fell about 20-to-30-feet and was pronounced dead when paramedics arrived, according to an Emergency Medical Services report.

Fire Capt. Chris Ah Mook Sang said it is unknown whether the man died from the fall or a previous medical condition.

The man was part of a local Korean hiking club and was not a visitor, Ah Mook Sang said.

When fire rescue crews reached the man he was not breathing and had no pulse, Ah Mook Sang said. He was flown by helicopter to a landing zone, where paramedics pronounced him dead.

On Saturday, a 23-year-old hiker who fell 300 feet from the Puu Manamana hiking trail above Kaaawa died at the hospital, police said.

The Fire Department helicopter airlifted the woman from the Koolau mountains after fire rescue personnel stabilized her, Fire Capt. Chris Ah Mook Sang said.

The incident happened just after 11:30 a.m., and Ah Mook Sang said the woman was taken to the Queens Medical Center at around 1:20 p.m. with “traumatic” injuries to her lower back and one of her legs.

According to police, she died around 1:35 p.m.

The Puu Manamana trail runs along the ridge that separates Kahana Valley and Kaaawa and is regarded as one of the most dangerous hikes on Oahu.
