Fine to ascend / descend on a gravel bike. May need to hike a small 20m section depending on tyre width as the stones get a bit bigger for a small section, would be fine to ride down though

Fine to ascend / descend on a gravel bike, not easy though :). There may be a small 20m section you have to hike depending on your tyre width as the stones get a bit bigger for a small section

Great descent on a gravel bike, smooth but with some little drops from the occasional step. Very fun!

I'd recommend avoiding it if on a bike. It's a narrow path used by a variety of modalities (dogs, prams, people on mobiles, bikes too) in both directions. Some sections have tree roots vigorously breaking out of the tarmac and can get pretty bumpy. Sections by bridges are narrow and impossible to see around.

Stunning views. Path gets very gravelly so care needed if you are less experienced off-road
