Anyone who has not been vaccinated or recovered must show a negative test (antigen or PCR) when entering Switzerland, regardless of where they come from and what means of transport they are using. After four to seven days in Switzerland, another test, carried out in Switzerland, is required. The result of the second test must be sent to the responsible cantonal office.
In Switzerland, until September 30th, the tests are free not only for residents, but also for tourists (once a week). Pharmacies and doctors are therefore obliged to offer free tests for visitors, but it is recommended to make sure that the chosen center is informed by calling. (The list of pharmacies can be viewed here; the list of doctors can be viewed here).
There is no obligation to test for vaccinated and recovered people with a Covid certificate or other valid proof of vaccination or recovery.
All persons entering Svizzerland - vaccinated, recovered and people who tested negative - must also fill out the entry form (Passenger Locator Form, SwissPLF). https://swissplf.admin.ch/formular
