Border formalities are minimal and correspond to European standards. To cross the border, a valid passport will suffice. Citizens of the European Union and some other countries may cross the border using a valid identity card however.
All those who need visas to enter Slovenia can get them at the Slovenian embassy or consulate in their country. Please be advised that a Letter of Guarantee signed by the organizers is needed to initiate the procedure.
Therefore, if you need a Letter of Guarantee please indicate that in Registration Form.
