The Bévéra Paillon is the area behind Nice before the Vésubie valley. The rock formation is predominantly what I believe is called a "schist" ('O' level Geology - taken a while ago) where the rock is sedimentary and one of its characteristics is that it flakes - easily erodes. This makes for paths which can change their course from one season to the next (by erosion) - steep inclines in places and broken paths. The region nearer Nice is quite densly populated and the paths can be busy - this becomes less so as you go north. That all said the scenery is dramatic and on the walks you are rewarded with ever changing vista. The area encompasses Sospel, Lucéram, Tourettes Levens and Coaraze.
