Day 12: Castro-Urdiales to Liendo – 16.8 miles (27 km)

The weather remained cloudy and refreshingly cool. Today’s route covered a moderate distance and was mostly flat, winding through charming towns and villages. We enjoyed scenic coastal views and gentle rolling hills along the way.

We got lost a couple of times. Navigating with electronic maps and yellow arrows can be tricky, as they don’t always align or point clearly. Still, it added a bit of adventure to the day!
