Arzachena lies in the north of Sardinia, 5 km from the coast of the deep gulf named after it.
The town stretches over the slopes of a hill and is framed by an impressive backdrop of granite crests.
In recent years the town has experienced a rapid growth in tourism and the extensive housing development in the area bears witness to this. The coastal district, in fact, embraces numerous tourist resorts, among which the most famous is unquestionably Costa Smeralda.
The surrounding countryside is also very interesting because it boast a number of fascinating prehistoric monuments.

• The Necropolis of Li Muri.
  This is a typical example of a collective burial ground in a 'circle", which characterises the prehistoric culture of the Megalithic circles of Arzachena.
  
  
• The 'Giants' Tomb' of Li Lolghi.
  This tomb is constituted by a long trench, delimited by a wall, built in dry stone slabs.
  
  
• The 'Giants' Tomb' of Coddu 'Echju.
  This burial monument is characterised by a granite stele, or stone, 4 m. high, which stands in the centre of a semicircular archway, built in square stone blocks, driven into the ground.
  
  
• The Temple of Malchittu.
  The structure is made up of an irregular atrium and a large chamber where visitors can see the remains of a bench. An underground passage opens up in the floor to the right of the entrance and was perhaps a drainage system for the sacred water of the Temple.
  
  
• The Albucciu Nuraghe.
  One of the most interesting prehistoric monuments in the area. It is, in fact, what is known as a "corridor" typology and extends horizontally over the area.
