How about a trip to Reunion

If you want to take the worlds longest internal flight, start in Paris and fly to Reunion. Yes, it is officially an internal flight within France, despite travelling over multiple countries and continents and even traversing hemispheres. This is a tropical volcanic island in the south Indian Ocean, only a short flight from Mauritius and one which contains everything from jagged, mountainous peaks and waterfalls, to rocky coves, palm-fringed sandy beaches, and quirky little towns and villages, including the capital, Saint Denis. Yes, it is a long way to go, but if you want a tropical island holiday that offers something like very few others, where you can exhaust yourself climbing an active volcano one day, and lounge on a beach the next, then consider the French island of Reunion!
