People: Today the island comprises French nationals, Africans, Indians and Chinese and is an eclectic and colorful mix of people and cultures. French is the official language. Though French mixed with a little Creole along with local influences makes the language a bit difficult for French purists to follows. English is not very widely understood.
Places to see:
Piton de la Fournaise is one of the most active volcanoes in the world. Yet, its eruptions are very safe. You can go very close and watch this live volcano safely. It is one of the most cherished sights on this island. Visitors almost always climb up this volcano. Twice a year, the volcano sends up fountains of lava with lights and sending the molten sea running down its side.
