No, Swiss citizens do not require a separate visa specifically for Zanzibar when traveling to Tanzania. The Tanzania visa requirements for Swiss citizens and other European Union countries are typically the same for both mainland Tanzania and Zanzibar.
When Swiss citizens enter Tanzania with a valid visa, they will have unrestricted access to travel between the mainland and Zanzibar. You will not need to go through any additional immigration or visa processes when traveling between these two areas.
Today, tourists from Switzerland can apply for a visa to Tanzania online through Tanzania immigration services. With the eVisa, tourists can stay in Tanzania for up to 30 days in a row. Swiss citizens are granted a one-entry visa.
Tanzania eVisa applicants get an email when their visa is accepted. Most customers obtain their approved Tanzania eVisa within 1 to 3 business days.
Your visa is delivered in PDF format. You should print it and bring it with you when you travel to Tanzania.
If your visa application is declined, you will be notified through email as well.
