Sri Kukke Subramanya Temple, about 5.5 hours from Bangalore.
Kukke Subramanya is known for Sarpa Samskara and Naga Pratishta rituals, and its location on the banks of the Kumaradhara river. It pairs naturally with a Dharmasthala visit on the same route.
See our combined Dharmasthala package to cover both temples in one trip.
