A teenage holidaymaker suffered serious injuries after falling 40ft from a cliff and landing on rocks.
The boy was hurt on Sunday afternoon when he fell at Cadgwith on the Lizard Peninsula in Cornwall.
Falmouth Coastguard received a call from the ambulance service at 4.20pm telling them the teenager had fallen and had landed on rocks.
Coastguard rescue officers from Porthleven and Mullion were sent to the scene, with a helicopter from RNAS Culdrose.
The boy was airlifted to the Royal Cornwall Hospital in Truro for medical treatment.
James Instance, from Falmouth Coastguard, warned of the dangers of walking along coastal paths.
"We understand he has sustained serious injuries and he was holidaying with his family in the area," he said.
"We would like to remind the public if walking along the cliff or coastline to take care and make sure that you are properly equipped for walking along paths.
"In particular remember to wear sturdy shoes or boots and check the weather forecast before you set out.
"Do not attempt to climb up or down cliffs unless you are properly equipped and trained to do so.
"Do not attempt to climb cliffs as a short cut back to the top. Do not attempt self-rescue.
"If you get into difficulty, call 999 and ask for the coastguard."Suggest a correction
