Soguksu was a natural district in Kizilcahamam, Ankara Province. It is about 80 km away from downtown. It was classified as a natural park in 1959. The park takes place in a volcanic region and thus has hot and cold water sources around it. The hills of Arhut and Tolubelen are the highest peaks of the park. Their altitude is around 1700m. It is the home of 160 bird species and other wild animals. The Scotch pine trees cover more than half of the park.
