Nor is Ben Nevis part of a National Park, yes, I know it sounds amazing but Scotlands highest mountain is not part of a national park and is looked after by a charitable trust that depends on donations to maintain the busy summit path, a path that sees hundreds of thousands of feet each year and has to deal with snow, rain, lots of it, and avalanches.
The path building team is careful to use only local rocks to maintain the path, often using a helicopter to lift rocks to the right places to repair the path. It can be really scary to have a helicopter flying over you as it uplifts huge bags of rocks directly above your head. I know the bags they use to haul the rocks are safe, but one day, without saying a word, my client and I instinctively speeded up to a gentle jog to get out of the flight path!
