We made it to Santiago, and after two days of rest (and eating and showering), we got up and set out for Finisterre, 90k past Santiago. This is the westernmost point of Europe, and the furthest a pilgrim could therefore go. This is a little debateable, but the yellow arrows pointed that way, so 3 days of walking later, we watched the sunset over the ocean. It felt like a good end to our trip.
We hadn´t planned on this added leg, but we are glad that we did it. It feels more complete now.
