It's worth a visit. It's a long way from everywhere, but a cool place. I spent a semester "studying" there! It may not have been the hardest semester I ever did in my student life, but it was good fun!! It has an active volcano, lovely beaches, good coral reefs, cracking waterfalls, mountains and interesting culture.
It was an uninhabitted island until the French East India company cast some mutineers there to die in the 18th century. They came back 12 months later to find them thriving, and so started using it for plantations. They brought slaves from around the world to work on the plantations, so the population is now a completely mixed race population with many families having physical characteristics associated with numerous people groups.
