Silbos is surrounded by gurgling rivers who twist between the cliffs, carving tolls (as they’re called in Xapurriau, the local variety of Catalan) or pozas (in Spanish)—crystal clear pools hidden in the rocks. 

It is criss-crossed by estrets (in Xapurriau) or barrancos (in Spanish)—ravines hewn into the valleys, sounding their gales with the rustle of juncars/juncales, the humid reedlands.
