Sitting on the peppery sands of Daman-Ganga that flows softly to hug the Arabian Sea, a few leagues away is Daman, a picturesque port town of indescribable loveliness

Temperate in climate round the year it is a getaway home in all seasons. A Portuguese enclave for four centuries and a half till the close the colonial rule in 1961, Daman has been a coveted prize for which princes and potentates, indigenous scraps and alien powers waged wars.

Try Daman once and you’ll be drawn to this scenic spot again and again. With rest, repose, fun & laughter with friendly and hospitable people, Daman is unparalleled
