Ytraberget is a peninsula in Hafrsfjord in Sola Kommune, Norway. Ytraberget is connected to Indraberget, and it divides Sørnesvågen and Grannesvågen. Harald Fairhair (ca. 865-ca. 933) fought the Battle of Hafrsfjord in 872 AD. In the Saga by Snorre a little isle is mentioned as the location where Kjotve the Rich fled.
The little isle is held to be Ytraberget, although it is now connected by a low isthmus of some 2 meters in elevation to Indraberget. It is thought that the earth's crust rebounding post glaciation over 1,100 years has exposed the connection between the two.
On the top of the hill there is a plateau about 100 x 50 m. This is the area where the old Bronze Age fortifications (Bygdeborg) are. There are three or four buildings that were a part of the ruined castle, all about 8 x 5 m. Near the top of Ytraberget there is a stone slab monument erected in 1972 by King Olav for the 1,100-year anniversary of the Battle of Hafrsfjord. There are good fishing and swimming possibilities at Ytraberget.
