Vandavasi Municipality identifies Tavalagirisvara Temple on Venkundram Hill about five kilometres from town and records puja on each full-moon day. That is the secure core of the tradition.
Karthigai makes the summit visible
In November or December, a great Deepam is lit above a gathering drawn from surrounding villages. The municipality’s figure of about one lakh people is a civic estimate, not an exact annual count.
Why there is no route pin here
A dependable exact OSM object for the hill shrine could not be read, so this guide refuses to invent a summit coordinate. Ask locally for the current trailhead, access and return.
Join without possessing the event
This is living worship, not a generic festival-of-lights performance. Respect queues, smoke and instructions; carry water, avoid risky night walking and never fly a drone over worshippers.
