Lake Gunung Tujuh or The Seven Mountain Lake in English is a volcanic crater lake in the province of Jambi, Indonesia, located at 1°42′23″S 101°24′42″E within Kerinci National Park. Although a young lake, in geologic terms, its surrounding volcano, Mount Tujuh, is old and not immediately obvious as
such. The name "Danau Gunung Tujuh" translates as "Seven Mountain Lake," a seeming reference to seven peaks comprising the forested rim. The tallest of them rises 2732m above sea level, while the lake surface sits at 2005m. The lake is a popular overnight hiking destination among Park visitors and is sometimes fished by locals. Mount Kerinci stands nearby.
