It has been named Iceland in Miniature, because many national sights can be found in the area, including the Snæfellsjökull volcano, regarded as one of the symbols of Iceland. With its height of 1446 m, it is the highest mountain on the peninsula and has a glacier at its peak. The volcano can be seen on clear days from Reykjavík, a distance of about 120 km. The mountain is also known as the setting of the novel Journey to the Center of the Earth by the French author Jules Verne. The area surrounding Snæfellsjökull has been designated one of the four National Parks by the government of Iceland.
The peninsula is one of the main settings in the Laxdœla saga and it was, according to this saga, the birthplace of the first West Norse member of the Varangian Guard, Bolli Bollasson. Other historical people who lived in the area according to the saga include Guðrún Ósvífursdóttir, Bolli Þorleiksson and Snorri the Goði.
Local fishing villages and small towns on the northern shore of Snæfellsnes include Arnarstapi, Hellnar, Rif, Ólafsvík, Grundarfjörður and Stykkishólmur.
Near Hellissandur is the tallest structure in western Europe, the Longwave Radio Mast at Hellissandur.
