Grand Bassin or Ganga Talao is a sacred lake, which is about 1800 feet above sea level and is situated 2 km to the east of Le Pétrin. The lake is one of the most important hindu pilgrimage sites outside of India.During the week there is an idyllic and calm atmosphere at Grand Bassin, whereas between the end of febuary and the beginning of march crowds of pilgrims are heading to the lake: when Maha-Shivaratree is celebrated, more than 400.000 believers make the pilgrimage to Ganga Talao to make sacrifices to their gods.According to a legend the lake is connected with the holy river Ganges. The god Shiva, the transformer and destroyer, and his wife Parvati were fyling around the world in a ship. Shiva wanted to show Parvati the most beautyful places on earth, so they stopped in Mauritius. During the journey, Shiva was carrying the river Ganges on his head, to prevent the earth from floodings. When they wanted to land in Mauritius, Shiva accidently spilled water of the holy river.
