A Taiwanese woman known as the "Bikini Climber" for hiking up mountains in swimwear has been found frozen to death after falling 19.8m in a national park.

On the eighth day of her solo hike, Gigi Wu, 36, used a satellite phone to call a friend after she fell down in a ravine in Central Taiwan's Yushan Mountain, Taiwan News reported.

Wu told her friend she was trapped at the bottom and unable to move due to the injuries to her leg suffered during the fall.

In a message to be passed on to the Nantou fire service, Wu revealed she had stumbled more than 19m into a narrow gorge while trying to ascend Taiwan's highest peak.
