The Şamı stream originates in the foothills of the Soğukoluk hill located about 15 km southwest of the Erfelek district of Sinop. It traverses a distance of almost two kilometers as it moves from one shelf to another at an altitude of 300 m. The valley covered with a dense forest, that appears to be stretching to the sky, is covered with about 30 waterfalls that were created by the cold, rapid waters of the Şamı stream and are called by the same name.

Perhaps after Diogenes and his father, who was in charge of the Sinope mint, were convicted of counterfeiting and were exiled, they dispersed their gold coins on these mountains. After all, why should the beautiful gold colors of the autumn leaves and the light brown hues of the earth not have something to do with the rain of gold they may have received 2 thousand 500 years ago?

Located on the northern slope of the Küre (İsfendiyar) Mountains, Erfelek extends over some 40 small and large villages scattered amidst the beech forests that grow profusely in the humid climate of the Black Sea. The empire of beeches starts at an altitude of 800 m. Between 300 - 700 m, the most common types of tree are oak, hornbeam, chestnut and redwood as well as the apple and pear trees whose fruit play an important role in the diet of the locals.
