There are many areas where it is forbidden to fly around the lake. If you go as far as possible without population, you can fly. Because the ban in this area is private and not public. Note that if you have a drone of 250g maximum you can use it in remote areas. That’s what I did. Observe the prohibited areas on the spot so as not to have a problem. You must absolutely register your drone on the dedicated Swiss site : chlogin.zd.eiam.admin.ch/auth/saml2/sso/IDP-PRIVATE
