Birthplace of Argentina’s top two tennis players, Juan Martín del Potro and Juan Mónaco, the attractive town of TANDIL, many of whose streets are cobbled with stones quarried from nearby, is set among the central section of the Sistema de Tandilia, a long range of granite hills. Beginning around 150km northwest of the town and running across the province to Mar del Plata, they seldom rise above 200m; close to Tandil, however, there are craggy peaks of up to 504m. Although this is not wild trekking country, the sierras are ideal for horseriding and mountain biking. The town itself is well geared for the holiday-makers who come all year on weekend breaks, with some excellent accommodation plus enticing delicatessens and restaurants and a lively, bustling feel in the evening. Tandil is particularly popular during Holy Week, when the Vía Crucis (Stations of the Cross) processions take place; they end at Monte Calvario, a small hillock topped by a giant cross, to the east of the town centre.
