Is Sion safe for solo female travelers?

Absolutely safe, people won't talk to you spontaneously on the streets except to help you or to ask you directions. You can dress as you want, you will only get a few stares but nothing more. I really like my country and its safety, especially in smaller town and villages.

Sion is a small town in Switzerland, one of the safest countries in the world. Most that happens are car accidents or when skiing. If you forget your phone or wallet somewhere no one would touch it so you can go back and get it, or someone will take it to the police station and they would call you. There are robberies but mostly in the main cities, bicycle or pickpocketing. In Switzerland, police registered a total of 432,000 offenses under the Criminal Code in 2019 (−0.2% compared with previous year), of which 110,140 or 25.5 percent were cases of thefts (excluding vehicles, −2.0%), and 41,944 or 9.7 percent were thefts of vehicles (including bicycles, −10.1%), 46 were killings and 161 were attempted murders. The number of cases of rape reported increased by 53 incidents or 8.5 percent over the previous year.
