Sleep in a tube! SwissTubes are a truly unforgettable vacation experience. Each of the original SwissTubes is a separate, enclosed living space with sanitary facilities (shower/toilet). The SwissTubes are designed for 4, 6 or 8 people. Freshly renovated and decorated with an eye for details. The large panorama windows in each tube offer spectacular views of the park, the lake, and the mountains. The SwissTubes also have a small terrace with a table and chairs.
