Sierra de los Padres is a string of rocky hills and ridges about 14 miles west of Mar del Plata. They are part of Tandilia's mountain range, actually a series of low rock-strewn elevations of precambrian origin extended from central Buenos Aires Province to Cabo Corrientes, a cape on the shores of Mar del Plata. These peaks are barely 270 mt high, surrounded by farms in the lower lands and by an exclusive neighborhood built on their slopes. Most local landscapes have panoramic views of the surrounding hills. Recreational activities include trekking, PPC, bouldering and a large Golf link. There is an annual trekking and climbing event organized by the "Club Andino Mar del Plata", with more than 300 climbers attending each October.
