Just putting feelers out for the experienced travelers here. My wife and I are flying from Wash D.C. to Zurich June 28 and plan to be in the Colmar region from June 29 - July 2. Is there anything I need to know about crossing borders into France when it comes to COVID or anything else? It sounds like border crossings may still require a certificate of vaccination... Do I just bring our CDC vaccination cards or is there a more involved process? Are they still wearing masks? Most of our trip is in Switzerland and it's wide open there, just wasn't sure about France. Thanks all!
