Makalidurga is an old hill fort that is located 10 kilometres from Doddaballapura. This is a popular trekking location and a pilgrim centre. The Makalidurga hill towers over the railway track and the trail curves around a temple before sloping upwards. At the top of the hill, there are ruins of a fort and a small temple. With hillocks close to each other, trekking here is easy for kids as well as exciting since the trail offers a mix of hills, forests and forts.
