The Kaļķupe River valley was established as the Pilsupe River (formed by Kaļķupe River and Mazupe River) crossed the Blue hills of Šlītere to the South of Vīdale and Kaļķi. The distinct river valley has a branched network of gullies in which Devonian sandstone has been uncovered and can be seen in some locations. Puiškalns Hill (located at confluence of Kaļķupe River and Mazupe River), which was used as a castle hill and as a sacred location long in the past, is one of the most distinctive parts of the area. It is a popular tourist destination in the Talsi District. Hillside forests, various kinds of meadows and a wide range of plants are also of value in the local environment.
