The Scottish Ambulance Service (SAS) was called to the city landmark just after 3:20pm along with their special operations response team.
An SAS spokeswoman said: “One ambulance and our special operations response teams (SORT) were dispatched to the scene and an 18-year-old male patient was extracted by our SORT crews and taken to the Edinburgh Royal Infirmary for further assessment.”
Details of the man’s injury and its severity have not yet been provided.
A picture taken this afternoon showed an ambulance in attendance along with specialist response teams and equipment.
It is understood there may also have been another emergency incident on the hill earlier today.
In August last year, a woman was treated in hospital for serious injuries after falling on Arthur’s Seat.
And in February this year, an air rescue operation was launched to extract an injured walker who had fallen on the hill.
Arthur’s Seat, an ancient volcano, sits about 820ft above sea level and is the site of a large and well preserved fort. It is also a site of Special Scientific Interest.
