The union territory of Puducherry (formerly Pondicherry; generally known as ‘Pondy’) was under French rule until 1954. Some people here still speak French (and English with French accents). Hotels, restaurants and ‘lifestyle’ shops sell a seductive vision of the French-subcontinental aesthetic, enhanced by Gallic creative types and Indian artists and designers. The internationally famous Sri Aurobindo Ashram and its offshoot just north of town, Auroville, draw large numbers of spiritually minded visitors. Thus Pondy’s vibe: less faded colonial-era ville, more bohemian-chic, New Age–meets–Old World hang-out on the international travel trail.
The older 'French' part of town (where you'll probably spend most of your time) is full of quiet, clean streets, lined with bougainvillea-draped colonial-style town houses numbered in an almost logical manner. Newer Pondy is typically, hectically South Indian.
Enjoy fabulous shopping, French food (hello steak!), beer (au revoir Tamil Nadu alcohol taxes), and plenty of yoga and meditation.
