Kalpakkam
Spend a half‑day to a full day in Kalpakkam: see the nuclear township, relax on the beach, then head to nearby Mamallapuram.
Kalpakkam is a small nuclear‑township on Tamil Nadu’s north coast. Its main sights are the Madras Atomic Power Station, a quiet beach and easy access to Mamallapuram. One day covers the highlights; a second day can be used for a longer beach stay or a day‑trip to the historic shore temples.
