There are demanding and challenging cross-country ski trails in many regions of Tirol. For example in Seefeld, where the Nordic World Ski Championships took place in 2019, in Hochfilzen, home to biathlon world champion Dominik Landertinger, or in the Tannheimer Tal Valley, where you can train on the original route of the Ski-Trail cross-country marathon. If you already have experience and want to work on your technique and fitness, you should choose difficult trails for ambitious cross-country skiers.
