Beach of los Quebrantos Nature · Soto del Barco, Avilés, Asturias A long stretch of sand by the mouth of the Nalón, in San Juan de la Arena, fully exposed to the swell of the Cantabrian Sea and backed by dunes. From it can be seen the comings and goings of the fleet that still works the ria. Together with the playón de Bayas, in the neighbouring concejo of Castrillón, it forms at low tide a continuous stretch of sand about three kilometres long; its own section measures about 810 metres long by 100 wide and is protected as a Special Protection Area (SPA) and Site of Community Importance (SCI). Its sand is dark because of its proximity to the river mouth, and the dune system behind it, much deteriorated, coexists with an already urban setting. It is suitable for surfing and has a nearby campsite, parking, lifeguard cover and an amphibious beach wheelchair for people with disabilities, although bathing near the river mouth is not recommended.
