This relatively unknown route in Parque Natural Cabo de Gata is an amazing discovery of the coastal region. It goes over high cliffs, through old forts, a hippie commune and cute small towns. It is stunning at every corner and should probably always include a dip in the sea!
The route traverses the whole national park and is marked by blue/white markers. The route here starts at the end of the road where it turns to a gravel track (no cars allowed) and ends at the other national park boundary. It is loosely described here: https://www.andyshiddeneurope.com/cabo-de-gata-spain and here: https://senderismovvamesia.blogspot.com/2018/02/la-senda-azul-integral-del-cabo-de-gata.html
I could not find official government websites about the route, although it was clearly marked from start to finish. Hiking bloggers have dubbed it the "senda azul" after the white blue markers, and I assume the amazing blue sea which follows you around.
