Tirupati
The forested Tirumala hills above Tirupati hide two sacred waterfalls — Akasaganga, a small fall that pilgrims bathe in on the way to the temple, and Papavinasam, a larger cascade reached by a forest trail and believed to wash away sins. Both falls are set in beautiful, peaceful forest that feels far removed from the pilgrimage city below, and the trail between them is one of the best nature walks in Andhra Pradesh.
Permits are required for the Papavinasam trail — collect them from the forest department office at the trailhead. The falls are most powerful October to December; they reduce significantly in summer.
