In addition to the village center, Orehek contains the hamlets and isolated farmsteads of Gradež, Nemci, Zabrežnica, Mlinar, Abram, and Androjne. Orehek lies on a slope below Mount Kojca and Jesenica Creek flows through the village. The soil is sandy and marly, and there are tilled fields on very steep slopes, which traditionally necessitated carrying the soil from the last plowed furrow to the top of the field. Below the village there are tilled fields and meadows in the area known as Dovšca, and above the road there are low-quality hay fields in the area known as Pod Kojca (literally, 'below Mount Kojca').
