All participants are required to show a valid passport on entrance to Turkey.
Citizens of some countries are required to obtain a visa before arrival from the Turkish Embassy or Consulate and some may obtain e-Visas via the website www.evisa.gov.tr before arrival. The most updated visa information can be received from the website of the Republic of Turkey Ministry of Foreign Affairs.
The best is to obtain and print your e-visa online before leaving home.
For further information please contact the nearest Turkish Embassy or Consulate to check the visa regulations.
