Grand chemin côtier

Highlight • Other

Beautiful path, we take advantage of the elements, the view, the flora and fauna. Plan some obstacle crossings which allow the horses and cows to be left in their enclosures.

So the wind is really strong here. One stretch (the one with a headwind) feels like going uphill all the time. On the way out I walked quite a bit along a now unmarked trail near the cliff edge. I therefore recommend a safe step and thistle/nettle-proof clothing ☝️

Beautiful hike above the chalk cliffs. ⚠️ Some sections are steep and partially unpaved!
