Map - Gränichen

Gränichen is a municipality in the district of Aarau of the canton of Aargau in Switzerland.

The river Wyna flows north at first and heads northwest thereafter. The valley has an average width of about 500 m. On both sides of the valley there are steep hills with tributary valleys and small high plateaus. The landscape is not dissimilar to that of the Tafeljura, even though - geographically and geologically speaking - Gränichen lies in the Midland of Switzerland.

The hills on the left side of the valley are (from north to south): Manzenberg ( 524 m ), Wällenen (524 m559 m), Moosberg (524 m550 m), Heidberg (566 m) and Pfendel (615 m). These are foothills of the Schornig (596 m), which marks the transition to the valley of the river Suhre. The hills on the right side of the valley are called Fuden (570 m), Räckholderen (566 m), Breitenberg (551 m) and Surberg (607 m). In front of the Breitenberg is the Schulthess (513 m) which has almost the shape of an ellipsis. The Dossen (532 m) und the high plateau of the Liebegg are foothills of the Surberg.

Near the southern border, at an average distance of two kilometers, there are three hamlets, which also belong to the municipality of Gränichen: Rütihof (585 m) on Moorbergs, Bleien (430 m) and Refental (490 m) between Breitenberg, Dossen and Surberg.
