I will probably never walk the Camino del Santiago, though I have it on good authority it is life changing.
I’m also pretty sure I will never hike any significant portion of the Appalachian Trail, similarly life-changing.
I did, though, do an hour long stretch of St. Declan’s Way this month. It’s a 104 km long pilgrimage walk, and the part I walked, once in moody mist and once in filtered sun, runs along a dramatic cliff near the village of Ardmore. Awe-some, and couldn’t we all use a bit of awe.
