Srisailam, around 180 kilometres from Kurnool, is one of the most important religious sites in Andhra Pradesh — the location of the Mallikarjuna Jyotirlinga, one of the twelve most sacred Shiva shrines in India, built in the Dravidian style with fine Vijayanagara-era stonework. The temple complex is substantial and busy, particularly on major religious occasions, when it draws pilgrims from across the region.
Beyond the temple, the setting is remarkable. Srisailam sits at the edge of the Nallamala Hills above the Krishna River, surrounded by dense forest that is part of the Nagarjunsagar-Srisailam Tiger Reserve — India's largest tiger sanctuary by area. The Srisailam Dam across the Krishna is one of the largest masonry dams in the world and visible from viewpoints near the town.
The drive from Kurnool winds through forest and is attractive in its own right. Road access through the Nallamala Forest is restricted during certain hours, so check timings before travelling. The nearest rail connection is many kilometres away; a car is by far the most practical way to visit.
