The proposal has been floated by Hoda, a charity which aims to bring the best out of young people using creativity and outdoor activity.
The proposed location is the woodland and scrub area which used to be known as Heriot Mount - situated beside Braidwood Gate and between Holyrood Park and the north end of St Leonards.
It sounds like a great idea. Much of the area is currently used by rough sleepers and accumulates rubbish regularly. (See here for a clean up organised by the Southside Association last year).
There is a local consultation in the Crags Sports Centre on Saturday 3rd November between 12 noon and 2pm. More details from these pages.
