Skandagiri, also known as Kalavara Durga, is an ancient mountain fortress located approximately 70 km from Bangalore city, and 3 km from Chikballapur in the Indian state of Karnataka. It is off Bellary Road ( NH 7 Hyderabad-Bangalore Highway), and overlooks Nandi Hills, Muddenahalli, and Kanivenarayanapura. The peak is at an altitude of about 1350 meters.
One of the ancient and oldest mutt of karnataka "Papagni mutt" is located at skandagiri hills. This mutt is considered to be one of the rare in its kind as it is believed that devotees sitting inside the temple premises, can feel the devotial vibrations. Special poojas are performed every Saturday.
Skandagiri is a great place for trekking. Don't take any guide's or local person's help as they may ask around Rs1000 as the real adventure will be only when you find the path to hill yourself. If you really want them, you can bargain. They will demand around Rs100/person but you can easily get the deal with Rs50/person. There is a temple (Papagni matt) at the bottom of the trek. Go to the right side of the temple, take immediate left and go further for 100 m on plain path before the trek starts to rise up. Remember to take left from planes into a very narrow path to hill. There are arrows all around on rocks which will let you know you are on track. At the top there are couple of makeshift shops sellng eggs, tea, noodles and cigarette. These are not available during night trek.
