In 1914 most of the land was added to the existing Killiney Hill Park, opening it to the public. In 1998, the local authority which owns the land drew up proposals to turn the quarry's west valley into a caravan halting site for travellers. The move met with opposition from local residents, climbers, and environmentalists, and the plans were eventually dropped. In May 2010 Dún Laoghaire/Rathdown County Council angered climbers when they removed several large boulders from the quarry, disrupting climbing routes and potentially damaging other climbing routes in the process.
