The Marble Circuit Trail starts at the Zufallhütte mountain hut in the Martelltal valley, where overnight accommodation is available. Follow the trail to Stallwies inn, overlooking the picturesque Zufrittsee lake from which panoramic views stretch past the Rosimalm mountain hut and Schluderalm mountain hut all the way to the Lyfialm mountain hut. Even from the beginning of the hike, one already gets a sense of the Stelvio National Park’s rich natural diversity. The numerous Alpine huts and refuges offering refreshment services and overnight accommodation enable hikers to fully concentrate on their hiking adventure without worrying about where to sleep or having to take care of other essentials.
