Gölcük fills a round volcanic crater 1300 metres above sea level, southwest of Isparta, and is enclosed by hills covered in volcanic ash that rise 150 to 300 metres above it. The lake measures 1.5 kilometres across and is up to 30 metres deep.
For years it has been where people from Isparta and the surrounding area go for a day out, for relaxation and for sport. The lake was registered as a nature park in 1991. Red pine, black pine, oak, cedar, acacia, mock privet and other maquis plants grow in the park, and its wildlife includes hares, foxes, squirrels, tortoises, snakes and various birds.
