Mount Athos is the easternmost leg of Halkidiki peninsula. Almost the whole of it is occupied by the autonomous monastic republic of the Holy Mountain, a self-governed area with 20 Orthodox monasteries.
At the beginning of the leg there are several villages that offer tourist services to visitors during the summer. The most famous of them, Ouranoupoli, is the border with the Monastic Republic and is known as the last earthly place on the peninsula. Ships with pilgrims depart for the Holy Mountain from Ouranoupoli.
The other village resorts on this leg are Ierissos and Nea Roda, small fishing ports with sandy beaches.
