The path is not particularly special for cyclists, quite bumpy. It is located in a swamp or moorland area, after heavy rainfall it may not be passable - I have experienced that.

Simply a great trail to push the gravel bike to its limit. Not much is going on here and you can ride as fast as the terrain allows.
