Halkidiki is the most popular tourist destination in northern Greece. It is actually a peninsula with three small peninsulas, known as the three legs of Halkidiki Greece. The first leg is Kassandra and has popular tourist resorts with organized beaches. The second peninsula is Sithonia, with less organized resorts and more secluded coves. The third peninsula, Mount Athos, is a close monastic community where entrance is allowed only to men and after special permission. Very interesting is a boat trip from Ouranoupolis that makes the tour of Mount Athos, a region with lovely beaches and impressive Byzantine monasteries. Tourist facilities are plenty in the beautiful beach resorts of Halkidiki.
