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[1] extended from central Buenos Aires Province to Cabo Corrientes, a cape on the shores of Mar del Plata.
These peaks are barely 270 mt (900 feet) high, surrounded by farms in the lower lands and by an exclusive neighborhood built on their slopes.
There is an annual trekking and climbing event organized by the "Club Andino Mar del Plata", with more than 300 climbers attending each October.
[2][3] The suburban area of Sierra de los Padres was founded on 6 January1950 by Real Estate entrepreneurs Alfredo Cobos, his brother Francisco Cobos and Roberto Bronzo, who bought lands on the hills to establish a green neighbourhood.
