The Upper Isar valley between Bad Tölz and the Karwendel mountain range is a paradise for cross-country skiers. Lots of cross-country ski runs with guaranteed snow in picturesque valleys and an authentic backdrop with elegant farmhouses and proud churches. These qualities are especially true for the Jachenau. Many films have been made in the valley such as the Brandner Kaspar (a Bavarian film) and a forest ranger moved around the valley on skis as early as 1885. The charming thing about the cross-country run is that it crosses the whole valley right up to Jachenau at the head of the valley and offers an impressive view of this enchanting landscape. There and back it is 35 km, which can be shortened by taking the regional RVO bus. Whoever wants it a little bit easier can take the bus into the valley and then ski gently back downhill. But the usual direction leads you from Leger via Tannern and Bäcker into the valley to the village of Jachenau, where you can stop for a bite to eat in style.
It starts in the hamlet of Leger, which is located at the beginning of the valley, when you approach from Lenggries. There’s a car park there and also a bus stop. So it’s easy to get here by public transport. From Leger the cross-country trail runs over flat meadows and offers a beautiful view of the wide valley floor on the way. The tour passes by impressive farmhouses, and there are especially beautiful examples of those towards the end of the valley. That the trail goes gently uphill, only 100 metres of ascent over the whole length of it, isn’t really noticeable. Enjoy the peace and quiet, the views of the Alps and the crisp mountain air. There is no shortage of places to rest on the way. In Leger, Tanner and in the hamlet of Bäcker there are small food stalls. Right at the end of the valley just before the village of Jachenau the trail makes a wide arc over the flat meadows. In Jachenau for example you can refill your energy reserves at the Schützenhaus and then start heading back. Or more leisurely cross-country skiers can even take the bus back to Leger or Lenggries.
