The small Kastenalm is located in the picturesque Hinterautal valley in Scharnitz. At 1,220 metres, extensive alpine meadows extend around the traditional wooden hut. There is neither a cooker nor electricity here, but delicious Tyrolean Brettljausen with homemade bacon and cakes made according to grandma's recipes. As a perfect bike & hike destination, you can cycle from the source of the Isar River to the Kastenalm by (e-)bike and explore the surrounding mountain ranges (Laliderwände and Gleirsch) on foot. Locking facilities for all kinds of bikes are of course available. Special tip: South of the Kastenalm, the Lafatschenbach river thunders impressively over 70 metres of rock into the valley.

The ascent to the Kastenalm begins at the Länd car park in Scharnitz, which is subject to a charge, either by (e-)bike or on foot. If you arrive by train or bus, walk 850 metres from the train station to the starting point at the Länd car park; from the bus stop at the Scharnitz municipal office/information office it is about 650 metres. From the starting point at the car park you walk through the Hinterautal valley to the idyllic source of the river Isar and further into the valley to the Kastenalm.


  • Isarursprung and Kastenalm. Ascent from the Länd car park on foot or by (e-)bike through the Hinterautal to the Isarursprung and the Kastenalm.
