A TAIWANESE woman, known as the "Bikini Climber" for scaling mountains in swimwear, was found frozen to death after a 20m fall, according to reports.

Gigi Wu, 36, was eight days into a 25-day solo hike on Saturday when she called a friend to say she'd tumbled down a ravine in Central Taiwan's Yushan Mountain and was unable to move because of a leg injury, Taiwan News reported.

Rescuers were only able to airlift her out 28 hours later because of poor weather conditions. But by then, the young woman was dead, officials said.

The overnight temperature in the area at an altitude of over 1670m was around freezing, said Commander Lin Cheng-I of the Nantou County Fire Department.

The mountaineer, also known as Wu Chi-yun, was a local social media star, known for posing on peaks in barely-there outfits.

Her official cause of death is still unclear.
