You can visit the surrounding areas such as Siviri, Afytos, Kallithea, the hot springs of Agia Paraskevi and also many other beaches in the peninsula. Chalkidiki is divided in three peninsulas. The third one, although it is in the area of Chalkidiki is not part of it. IA World Heritage Site and autonomous polity in the Hellenic Republic, Athos is home to 20 stavropegial Eastern Orthodox monasteries under the direct jurisdiction of the patriarch of Constantinople. Today Greeks commonly refer to Mount Athos as the "Holy Mountain". In Classical times, while the mountain was called Athos, the peninsula was called Akté. The Holy Mountain is about 50 km long, with its width being 8-12 km and its area being 350 km2. Mount Athos is a huge mountain that divides the area with a height of 2.033 metres.

Only men are allowed in the Holy Mountain. However, the peninsula is accessible to everyone through the sea with small boats or luxurious yachts that travel back and forth all day long from Sithonia as parts of organized cruises.

Petralona is a small in Chalkidiki. It is 6 km NW of Triglia and 35 km SE of Thessaloniki. It is famous for the eponymous cave at about 1 km from the village, the Petralona cave in which was discovered one of the earliest European humanoids. The Petralona cave, at the foot of Mount Katsika, was discovered in 1959 by a local looking for a spring. In it was found in 1960 the Petralona skull, extremely well preserved, dated to more than 700,000 years. It was named Archanthropus europaeus petraloniensis. This is considered as one of the oldest European Homo erectus specimen found so far (ca 1.000.000 years old).
