From the air, the mountainous southern coast of Yogyakarta Province in Indonesia presents a unique view of the conical hills of UNESCO Global Geopark, Gunung Sewu, which means “thousands of mountains” in Javanese. The verdant landscape stretches in a 120 km band east to west, from the misty green hills to the coast, sandwiched between the active volcanoes of Merapi and Lawu in the north and the Indian Ocean in the south. A unique karst landscape, it features rocky cliffs, conical hills, caves, underground streams and sinkholes.
