It is said that the god Shiva, and his wife Parvatti, flew over Mauritius bearing on his head the Ganges River, he was so moved by her beauty that a few drops fell to the ground, forming the Grand Bassin (Ganga Talao). If we consider this legend, we realize that it is the most sacred place in the world outside India. This is a source of great pride for 500,000+ Hindus who make up half the population of the island. When we went there was almost no one there, the odd faithful making a small offering, but not much more. Most likely they were preparing for Diwali, the festival of lights. It is not really touristy, and I advise you not to go if you don't have respect and can't observe basic etiquette rules.
