is a natural beach, between the beaches of Cala Bona and Cala Jugadora. It is characterized by the rock formations that surround it. Oriented to the south, it has a length of 13 m and a width of 22 m, made up of gravel, pebbles and blocks. Access is difficult, by a path that goes down from near the end of the road that reaches Cap de Creus. It is a quiet beach, sheltered from the north wind. Nudism is practiced there. The name of the beach is a diminutive of the word illes (illes means islands in Catalan) in Cadequesenc (the slang of cadaques), in reference to the set of small islands that are at the entrance from the sea: ses Ielles and s'Estufadora.
, a Neolithic settlement, reveals a glimpse into ancient urbanism and cabins. The site, spanning 800 m², showcases well-preserved remnants of sub-rectangular houses forming a 'U' shape, an isolated oval cabin, and traces of communal life. The oval cabin, measuring 10 x 7 m, likely served as a communal hub for cooking and essential activities. Archaeological phases, from the early to late Neolithic, reveal evolving structures and cultural artifacts. Nearby, the Serra de Rodes and Cap de Creus boast a concentration of dolmens, illuminating the region's megalithic heritage. Ca N'Isach offers a remarkable window into Neolithic life, with a rich history spanning millennia.
