My wife and I are considering a quick trip to Colmar, France sometime during the holiday season. We would likely fly into Zurich, as that appears to be the closest major airport, and then drive to Colmar.
My question regards Covid alert levels. Switzerland currently has a CDC level 4 Covid alert, while France is level 3. What are the Covid rules in Europe when traveling between countries? I have no idea if the EU has similar alerts for the different countries or not.
