Currently, tourists visiting Southern Africa must apply for separate visas for each country, each with its own visa regime. For some, this acts a deterrent for multi-country travel in the region. It is for this reason that the development of a common visa, deemed a UNIVISA, was endorsed by SADC Heads of State in 1998. While there have been some obstacles to implementation, significant momentum is now building towards the UNIVISA. The KAZA (Kavango Zambezi) Univisa covers travel within Zimbabwe and Zambia and covers day trips into Botswana via the Kazungula border post.
