Lots of holiday homes in Allihies, so specifically Coppermines holiday homes... Go through village bear right and go past the coppermines holiday homes and then there is a track up to your left. You can go all the way up this tarmacked. Other side is gravel. Somewhere along the tarmac bit you will find a place to stop.
People do drive over this road, but not often maybe one or two a day... I am not there so thats one less
