The teenager was camping on Cave Hill when she fell
A 17-year-old girl is critically ill with severe head injuries after falling from Belfast's Cave Hill.
The girl, who was camping with friends, fell about 20 metres from Napoleon's Nose down a cliff into deep undergrowth.
The incident was reported shortly after 0130 BST on Sunday and about 25 firefighters were involved in a rescue operation.
Ambulance, Coastguard and PSNI personnel also took part.
A fire service spokesperson said the operation "was very complex in difficult conditions and lasted approximately three hours."
They added: "The rescue involved line and steep angle rescue equipment."
Finton Grant, manager of Cave Hill Park, said people should be aware of the dangers.
"People need to be aware that they need to stick to the path structure that is there," he said.
"We have invested a lot of money especially along the front of the caves and up around to Napoleon's nose.
"We try to make as safe an assent as possible. As long as people stick to those areas they should be ok."
Last Monday, a nine-year-old boy was injured after falling from Cave Hill while out walking with his father.
