TAIPEI (Taiwan News) – Rescue teams had to venture into Yushan National Park to save hikers 10 times in 12 days, reports said Wednesday (Dec. 11).

The area in central Taiwan surrounds the country’s tallest peak, Yushan, at 3,952 meters above sea level. The national park straddles Nantou, Chiayi, and Kaohsiung.

In the latest case, a hiker surnamed Lee (李), 71, fell down a slope while hiking as part of a 10-person group on the Batongguan Traverse Trail, per CNA. He had head injuries and a fractured left arm, and was unable to walk out of the area.

As a rescue team needed a full day to reach him, the Nantou County Fire Department decided to call in the National Airborne Service Corps. A helicopter picked up Lee on Wednesday at noon and flew him to the Fire Service Training Center at Zhushan, where an ambulance waited to transfer him to a hospital.

Over the 11 days from Nov. 30 to Dec. 10, nine accidents occurred in the mountains. Adding Lee to the total, 10 incidents were recorded in the park over 12 days.

Most of the individuals were aged between 55 and 65, according to the data. Yushan park management called on hikers to take all the necessary measures to prepare for their trips and not to overestimate their physical capabilities to reduce the risk of accidents.
