I went for a walk yesterday along the path that leads from the Plaza de Lavaderos in La Caleta along side the sea. It was a strange day weather wise, grey and overcast, dull and looking like rain, which later turned to full on sunshine. Even though the weather was a bit questionable at the time, it was still a lovely walk.
There is a small book available at the tourist office on the official marked walks and trails in the area. They have walks listed for all level of walker out there, so even if it is not something you usually do, there will be a trail suited to your level of physical ability. Happy Trails.
