A 30-year-old woman was airlifted to hospital on Sunday after falling 100-foot down a south Pembrokeshire cliff.
The woman, who is from the Tolworth area of London, had been climbing near Flimston Bay between St. Govans and Stack Rocks when the accident happened shortly after 8.30 pm.
One of her companions, a nurse, who had been on the headland, scrambled down the cliff to her and gave her first aid, while her fellow climber raised the alarm.
A helicopter from RAF Chivenor in Devon was scrambled and the coastguard rescue team from St. Govans, with assistance from their colleagues in Tenby, were tasked.
Police and an ambulance crew also attended.
The woman, who is believed to have sustained serious head, arm and pelvic injuries, was initially airlifted to Withybush Hospital, Haverfordwest, before being transferred to Morriston Hospital the following day.
The second female was rescued by the coastguard rescue team.
Milford Haven coastguard watch manager, Keith John said: "The coastguard rescue ream reported to me from the scene just how expertly the helicopter crew had managed to get in close to the area where the woman needed to be winched from. Flying a helicopter close to the cliff edge demands great courage and skill, which ensured this woman got the medical help she needed as soon as possible."
