Nandi Hills Caves are situated near Brahmashram. It is a perfect spot for those seeking silence and solitude. The Shiva Temple inside it, is a great place for worship and relax.
There is a ashram that was constructed by natural boulders into a beautiful cave. This site was the meditation place of Sage Ramakrishna Paramahamsa, who was one of the greatest devotees of Goddess Kali.
