The French colonial town of Pondicherry was under French influence and rule for a long time. A walk down the French side is interesting with colonial houses and streets. Auroville houses the Aurobindo Ashram and people from all over flock to visit and some even stay for higher learning of the sciences and yoga here.
Chidambaram, Kumbhakonam and Gangaikondacholapuram are some of the small towns that fall between Pondicherry and Tanjore, which are known for their famed temples. All of which are enroute this circuit.
