An island of extraordinary beauty, it bubbles with life and vibrates under the power of nature. Eruptions, earthquakes and tsunamis are Sumatran headline grabbers. Steaming volcanoes brew and bluster while standing guard over lakes that sleepily lap the edges of craters. Orangutan-filled jungles host not only our red-haired cousins, but also tigers, rhinos and elephants. And down at sea level, idyllic deserted beaches are bombarded by clear barrels of surf.
