TANDIL, 70km southeast of Azul, is set among the central section of the range of hills known as the Sistema de Tandilia. The range begins around 150km northwest of Tandil, running across the province to Mar del Plata, on the coast, and only rarely rising above 200m. Around Tandil, however, there are peaks of up to 500m. This is not wild trekking country, but Tandil’s hills are good for horse-riding and mountain-biking. The town itself is well geared for the holidaymakers that come all year on weekend breaks, with some very good delicatessens and restaurants and a lively, bustling feel in the evening. Tandil is particularly popular during Holy Week, when the Via Crucis (Stations of the Cross) processions take place, which end at Monte Calvario, a small hillock topped by a giant cross to the east of the town centre.
