A car is unnecessary on site anyway: vacationers can usually use the public transport network free of charge with their guest card.

Visitors stay in the Explorer Hotels themselves, built in sustainable passive house technology. Thanks to their excellent insulation and thermal insulation, these hotels require only 15 percent of the heating energy of a similarly sized hotel. The ecological footprint remains small, but the experiences are still great: all ten locations serve as base camps in the mountains and offer vacationers unforgettable and environmentally friendly outdoor activities.
