I would like to correct (sorry for my english):

Path 1171238027
part of Trans Karavanke (16337182)

I went there month ago by bike. It is not possible to ride that, even walking is difficult (fallen trees across the road, waterlogged, later the road disappears or turns into a steep slope with no visible track).

I think path 1306980664 is usable variant for MTB (tried partially, someone should verify).

I think Trans Karavanke (16337182) should be re-routed here by 1306980664, while 1171238027 should be clasified as not for bikes and difficult for walking.

I can send some photos when needed.
