Lubang Sewu is a very incredibly beautiful place located in the town of Wonosobo, Central Java, Indonesia. Lubang Sewu means a hole with many holes. From the legend of the ancient Central Java society, it is said that when the water was in a recession, this rocky area left traces of small holes. The scenery of this rock resembles the area of the Grand Canyon in the United States. These rocks come from limestone rocks with a fairly rough harvest.
