A 48-year-old woman died after falling off a steep cliff, known as ‘Suicide Cliff’ on Hong Kong’s Kowloon Peak on Wednesday.

Apple Daily reports that the woman, surnamed Lee, went hiking with a group of 12 friends on Kowloon Peak, known as Fei Ngor Shan in Chinese, at 9.30am.

They arrived at the area near ‘Suicide Cliff,’ at the top of the mountain, at around 1pm. Lee is reported to have slipped suddenly and plummeted 20 meters.

She sustained injuries to her head and limbs and was unconscious. Due to the precipitous terrain, it took around two hours for a rescue team to airlift Lee from the mountain on a helicopter. She was taken to Pamela Youde Nethersole Eastern Hospital and pronounced dead.

‘Suicide Cliff,’ on the mountain’s southwest face and part of Ma On Shan Country Park, is popular with hikers and photographers for its panoramic views of the city. As Oriental Daily observes, it is not an official trekking route. However, as the highest mountain on the Kowloon Peninsula, it involves scrambling up narrow paths and  attracts ‘advanced’ hikers.

Lee’s death was the second fatal hiking accident in Hong Kong in four days. On Sunday, a 69-year-old man fell to his death while trekking on one of the most difficult hiking trails on Lantau Island.
