Île Thérèse is a small, uninhabited island located off the western coast of Mahé, near the Port Launay Marine National Park. Spanning approximately 0.7 square kilometers, the island rises to a maximum elevation of 160 meters, featuring a diverse landscape of sandy shores and forested hills. It is surrounded by a spirited coral reef that provides excellent conditions for snorkeling and diving, with frequent sightings of sea turtles and reef sharks. Historically, the island was used for coconut cultivation, evidence of which remains in the groves of palm trees. Today, it serves as a popular destination for day trips and picnics, accessible by a short boat ride from the beaches of Port Glaud or Grand Anse. The long, white sandy beach on the eastern side is well-protected, offering crystal-clear and calm waters. The island also supports various seabird species and a healthy reptile population, making it an important local ecosystem.
