Tirupati
Fifty kilometres from Tirupati, the ancient Sri Kalahasteeswara Temple is one of the Pancha Bhuta Stalas — the five temples representing the five elements of nature, with Kalahasti representing air (vayu). The temple sits at the base of a hill on the banks of the Swarnamukhi river, and its gopurams soaring above the riverside are one of the finest pieces of Dravidian temple architecture in South India.
Kalahasti is renowned for Rahu-Ketu puja — a ritual to mitigate astrological doshas — which thousands perform here. If this applies to you or you are curious, arrive early as priests are in high demand.
