<div dir="auto">Hi Keith. <div dir="auto"><br></div><div dir="auto">My understanding (and practice) is to map the top of the cliff edge. You can then add an area of natural=bare_rock if the cliff is a slab and extends out 'beneath' the top edge (of course, there may also be flat bare rock along the top edge and perhaps at the bottom). </div><div dir="auto">The wiki recommends path=climbing_access for dedicated crag access, used 1188 times apparently without additional tags (e.g. highway=path): <a href="https://taginfo.openstreetmap.org/tags/path=climbing_access#overview">https://taginfo.openstreetmap.org/tags/path=climbing_access#overview</a> </div><div dir="auto">Personally I would just add them as footways if their placement seems reasonably stable (with additional tags as appropriate). </div><div dir="auto">You can add the starting point of each route with climbing_route=bottom <a href="https://wiki.openstreetmap.org/wiki/Climbing">https://wiki.openstreetmap.org/wiki/Climbing</a> although I haven't done this as I am unsure about the appropriateness of any source of names.</div><div dir="auto"><br></div><div dir="auto">P.S.
