The Peak District National Park Authority is considering selling Stanage Edge in a bid to save money.
The authority is looking at a number of options to compensate for a 30 per cent budget cut from central government, including selling the iconic landscape.
But the British Mountaineering Council (BMC) has immediately slammed the idea and launched a petition opposing the potential sale.
A BMC spokesperson said: “We are calling on climbers, walkers and everybody with a love for Stanage Edge to sign a petition to help safeguard its future.
“Stanage is the most popular crag in Britain, maybe in the world, but decisions are being made that could change it significantly – and we need your help to state our case.”
However, Peak Park Chief Executive Jim Dixon insists there is “nothing in our plans that will harm the interests of the North Lees Estate,” of which Stanage Edge is part.
He said: “The Authority has a track record of making important decisions on land and properties that have improved their overall contribution to the national park.
“It is early days for our consideration of the future of the North Lees estate and no decisions have been made. I welcome the BMC’s input to our debates.”
The authority also insists that, whatever the future, access would never be restricted to tourists.
