Ganga Talao or Grand Bassin is a crater lake situated in a secluded mountain area in the district of Savanne, deep in the heart of Mauritius. It is about 1800 feet above sea level. It is considered the most sacred Hindu place in Mauritius.
There is a temple dedicated to Lord Shiva and other Gods including Hanuman, Lakshmi, and others along the Grand Bassin. During Shivaratri, many pilgrims in Mauritius walk bare feet from their homes to the lake.
