Home to one of the world's most active volcanoes, snow-capped Piton de Fournaise, Reunion is a little known gem. This rocky, French-governed island off the coast of East Africa is easily explored by Les Cars Jaunes, yellow buses that link main settlements. The road into the mountains provides breathtaking scenery. Bike tours on rough back roads are an option for the brave and the extremely fit. Beyond the reach of cars, untamed village Cirque de Mafate shows the island's wildest side.
