Tirumala Sesha Theertham History, Route

Allowed every year only on Vaisaka Suddha Purnima day in Feb-Mar.
6 km to the main temple towards Durgamaranya Parvatam Sanuvullu. Vehicles can go up to 2 km. Takes 2-3 hours to reach. Can see 5-7 small ponds on the way.
Theertham is covered with 100feet of height, 30 feet breath hill.

Need to cross Balaji colony (resident place for Tirumala locals). Another way is from Mamandur/ Kukkala Doddi side (presently banned due to sandal scam). A guide is mandatory.
Associated with the Adishesha/ Sheshnag, who once stroked a torrent with his tail for quenching the thirst of Sri Vishnu.
Devotees taking a holy dip in this theertham offer jaggery, salt and pepper to pray for the betterment of their health. Gets relief from the Sarpa Dosha.
