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
