The crime rate in Champery is very low. However, beware of pickpockets and purse snatchers. They become more active at the height of the tourist season.
Most crimes occur in areas avoided by prudent tourists, where drug dealers reside. You should also be cautious at train stations, public transportation, and airports. Be vigilant on overnight train rides to neighboring countries. Thieves can even get into closed compartments to rob sleeping passengers.
As far as safety on the slopes is concerned, Champery pays particular attention to it. All elevators are regularly checked for serviceability and the slopes are well marked. There are several ski schools with experienced instructors who can teach skiing skills not only to adults but also to children.
