Sunglasses, a hat and a high UV sunscreen should be the first items you pack.
Beachwear is a popular form of dress in Mauritius. Otherwise, dress is casual although most hotels do not allow guests to wear shorts or T-shirts in the restaurants or bars in the evenings. Between June and October a jacket or jersey is recommended for the cool evenings. Dress appropriately when visiting religious shrines and remove shoes when entering mosques and temples.
