Greendwa is a famous skiing area of Jungfrau Peak. It has a unique and magnificent Alpine landscape. As a base for skiing, boarding, hiking and other tourists, there are many hotels and restaurants of different sizes. The main external traffic is train traffic to and from Interlaken. Even in summer, it's usually over twenty degrees, so there's no air conditioning in the cabin! If it's too hot in summer, you need your own fan.
