Land of sand and fire. Bromo Tengger Semeru National Park, East Java, Indonesia

Welcome to the spectacular Bromo Tengger Semeru National Park, on the Indonesian island of Java, famous for stunning sunrises and its dramatic landscape. Here, a massive ancient volcano erupted thousands of years ago and inside its collapsed crater, more volcanoes formed.

To the left, spewing smoke and steam, is Mount Bromo, one of the most iconic sites in East Java, which has erupted at least four times in the last 20 years. In the forefront of the picture, with trees creeping up the sides, is Mount Batok, which is no longer active, while Java's highest mountain (and active volcano) Semeru, is visible in the background. The Tengger Sand Sea, a vast area of fine volcanic sand, wraps around five volcanoes inside the caldera. No wonder this massive national park is sometimes referred to as the land of sand and fire.
