As a Greek passport holder, you'll be delighted to know that entry to Zambia for tourism is visa-free, allowing you a generous stay of up to 30 days on each visit, with six distinct tourist visa types available should you wish to extend your adventures beyond this initial allowance. When planning your journey, consider that while direct flights are uncommon, common routes often transit through hubs like Amsterdam or Doha, so factor in potential layover times and the considerable distance between Athens and Lusaka. Remember to exchange some of your Euros for Zambian Kwacha upon arrival, as while major establishments may accept cards, local markets and smaller vendors often prefer cash.
