At many of our lodgings you can sleep in a sleeping bag if you have a bed sheet and pillowcase with you. However, it is up to the host to decide if it is allowed or not. Contact the lodging in advance to make sure you know what applies. At mountain stations and mountain cabins it is obligatory to bring your own sheets and pillow cases (at our mountain stations you can also rent this on spot) in addition to your sleeping bag, travel sheet or duvet cover for the duvets in the cabins. You will need to be able to cover all bedclothes for your own safety.
