Nallamalla

The Nallamala Hills form part of the Eastern Ghats, running north to south between the Krishna and Pennar rivers. The broad basin of Palnadu lies at their northern end, while farther south the hills join the ranges around Tirupati. Their weathered ridges rise above forested valleys, with peaks including Bhairani Konda and Gundla Brahmeswara to the northwest of Cumbum. Sacred places such as Ahobilam stand within the wooded hill country.
