Switzerland/France. I've seen farmers take their mobile milk-carts up mountains to milk them in-situ. Not sure whether they do the same thing with calves or not though.

So called "Mutterkuh-Haltung", where the calves are kept with the mother, is increasingly popular. This occasionally causes problems, as hiking paths often intersect grazing ranges, and cows will defend their calves aggressively from perceived threats.
