welcome to this forum, welcome in Mauritius. Have a great time and enjoy yourself in a different culture.
I am not sure about your age, but as you said you are an intern you might be in the age of an university student. If so, why not trying to get in touch with the University of Mauritius (UoM). There you'll find many young and open minded Mauritians as well as students from other parts of the world too. From time to time they organise parties, trips to interesting places in Mauritius, and many of them love to do sports. That might also be a perfect activity to make new friends.
Just have a look here: http://www.uom.ac.mu/
All the best
