The historic Borgarfjarðarsýsla may not be one of the largest geographic areas in Iceland, but many of the historic sagas feature this region.

This region includes the towns of Bær, Hvanneyri, Leirá, Miðsandur, Reykholt, and Sólmundarhöfði.
Natural features include the waterfalls: Hraunfossar (Lava Falls), and Barnafoss (Children's Falls). Barnafoss receives water from the Langjökull glacier.


Deildartunguhver hot springs are also located in Borgarfjarðarsýsla. It is the most powerful hot spring in Europe and is harnessed for central heating in the towns of Borganes and Akranes.

The museum Snorrastofa in Reykholt is a cultural and research center for medieval studies and the history of Borgarfjarðarsýsla.

This was the home of Snorri Sturluson, the twelfth-century chieftain, poet and author of Snorra-Edda and Heimskringla, a history of Norwegian kings from the 10th to the 12th century.
Snorralaug (Snorri's Pool), was mentioned in Landnámabók (Book of Settlements), as a 12-century wonder for the ingenious way that it harnessed geothermal water for bathing.
