Tiruvannamalai reaches by rail into its own station (TNM) — a reported ~223 km rail run from Chennai, with Bengaluru-side and Dadar–Puducherry services also calling — or by road: ~200–224 km from Chennai, ~200–210 km from Bengaluru, and just ~100–130 km from Puducherry (the classic coastal pairing). The temple and ashram belt is walkable from the station.
