Lüsen (; ) is a comune (municipality) in South Tyrol, located about northeast of the city of Bolzano.
Lusen is a mountain in Bavaria ( Germany) and in the Plzeň Region ( Czech Republic). Its peak is about south of the Czech Republic–Germany border. Streams forming on the north side become tributaries of the Vydra.
The Lusen is popular for hiking in summer and winter. There is a winter trail which is usually cleared of snow. However the bohemean wind might blow rather strongly and covers everything in ice as you can see in this panorama shot of the summit.
The winter trail is also ideal for sledging.
