While in Switzerland, I stayed in a small family-run inn in the mountains. In order to get there, we had to hike for three hours because there are no access roads through the rugged terrain. Obersteinberg (the name of the inn) gets all of their food and supplies either by mule or by helicopter. Once a week, a helicopter comes and takes all of their recyclable materials and delivers the food, drinks and other supplies. Occasionally, they also give a ride down the mountain to family members at the inn. In this video, you can see how quickly it all happens.
I found it interesting that the family at this inn is so environmentally conscientious. Rather than burning their trash/recyclables (which may be easier, but worse for the environment), they arrange for a helicopter to pick it all up and dispose of it properly. As Julian, the 12-year-old boy who lived there said, "I love the mountains. The are my best friends."
