A man is recovering from serious injuries after falling 20 feet down a large hole on the north coast of Cornwall.
The 56-year-old was exploring with a group when he tumbled to the bottom of the roundhole at Trevone Bay near Padstow, on Tuesday evening.
One of the group stuck with him until a helicopter rescue team could winch him out and fly him to Derriford Hospital.
Footage of the rescue, which lasted around four hours, was released by Falmouth coastguard.
The whole event was witnessed by Rob Stevenson who filmed the search and rescue helicopter in action.
Phil Davies, of the Maritime and Coastguard Agency, said: "We always advise people not to attempt to self-rescue in these circumstances. "This man's friend did exactly the right thing by just staying with him while the alarm was raised.
"It's also worth reminding people that while our coastline is beautiful, it can also be very dangerous."
"As always, call 999 and ask for the Coastguard if you get into difficulty or you see someone else in trouble."
