Trekking tours at expert level, heavier treks for adventurers
For tough adventurers, there are spectacular heavier trekking tours in the high mountains, crossing glaciers, mountain ridges or technical routes. During heavy treks you will hike or climb for at least 8 hours a day and you cross 1000 (+) or more altimeters (only up). Often you need special techniques and materials to cross glaciers or technical routes. You carry a heavier backpack.
During heavier trekking tours you do not always sleep in a mountain hut but possibly also in a bivouac. Heavier mountain trekking tours are not without risk. You can only do this with the guidance of a certified regional alpine mountain guide unless you have followed alpine courses or have sufficient experience.
