Ganga Talao, also known as Grand Bassin, is a sacred lake and important pilgrimage site located in the crater of an extinct volcano in the interior of Mauritius. Situated about 550 meters above sea level, it is considered one of the most significant Hindu religious sites outside India. The lake is believed to be the earthly replica of the Ganges River in India, making it a central spot for the annual Maha Shivaratri festival, which attracts thousands of devotees.

The site features a number of Hindu temples and shrines, including a large statue of Lord Shiva, which stands prominently on the shore of the lake. Visitors can explore the tranquil surroundings, take part in religious ceremonies, and witness traditional rituals and offerings. The area is surrounded by lush greenery and volcanic landscapes, adding to its serene and spiritual atmosphere. Ganga Talao is not only a significant place of worship but also a popular destination for those interested in exploring the cultural and spiritual heritage of Mauritius.
