My daughter (12) speaks good Spanish and is an intermediate club swimmer. Our family wishes to find a swim camp where she can up-grade her swim skills and practice her Spanish. Other family members would seek language or art lessons. We have been Central American residents and seek an authentic Spanish location that is not an "extranjero" enclave. Would this eliminate Mediterranean locations? Your tips are greatly appreciated.
Yes, this would probably exclude Mediterranean beaches. But, on the other coasts you have Santander (Univ. Internacional Menendez Pelayo), People of Cantabria speak el Castellano extremly Fast. My Madrilena wife had a hard time keeping up with it. The 'Jewel' of the Coast is Sardinero Playa. On the Atlantic Coast, There's a University in Baiona (West from Vigo); it's Playa Samil. There are also bagpipe (Gaita Gallega) competitions in Vigo each May.
My last visit to Galicia, I flew Madrid to Santiago, then continued by Bus to Arosa, where I would wait for Saturday and the Pilgrims' Mass (complete with Botafumeiro). Arosa is a sleepy fishing village, on the Coast. There's a beach but nothing to brag about.
Llanes, in Asturias is the only other excellent Beach on the Mar Cantabrico I would recommend.
If you go, Bilbao is aleays a good place to buy Quesos de cabra, Morcillas & Chorizo's to make a nice Favada.
Santander has its Annual Fiesta week between San Fermin & Santiago. There's Flamenco & Jotas (my favorite) - Avda. de Burgos really 'gets it on.' That's around mid-July
