At least since the early 20th century there is a movement of people wanting to do some things together, while they were nude. Sometimes it was just seen functionally, like a common bath in a pond or lake. Some people do other activities together (in the nude), where being naked is usually not required. For instance, some people prefer nude sunbathing when otherwise a swimsuit could be worn. There are some nude bicycle tours. This movement is generally known as naturism or nudism. In 2009, Appenzell Innerrhoden, a small Swiss canton, voted to stop nude hiking. German tourists have been walking nude through the Alps wearing only boots, socks, and a back pack. The canton will fine nude hikers 200 Swiss francs.
