Byfjorden (the Cityfjord), with its water depths ranging from about 5 to 350 meters frames the city of Bergen along its waterfront. It is also a natural landmark, visible from much of the city as it is situated between the seven mountains that encircle Bergen. The 15-kilometre (9.3 mi) long fjord separates the island of Askøy from the mainland Bergen, passing right north of the city of Bergen on the mainland.

The 4 kilometer long and up to 500 meter deep Salhusfjord is located between Bergen and Alver Municipality. The fjord is crossed by the Nordhordland Bridge. The fjord takes its name from the village area of Salhus. In the early 12th century there was an inn located there, known at the time as a sáluhus. It acted as a transport hub for Nordhordland, and was a small market town. It was one of the first industrialized places when a hosiery manufacturer was established here in 1859.

The Nordhordland Bridge is an impressive landmark just north of Bergen, carrying the coastal road across the wide Salhusfjord. Opened in 1994, it combines a slender cable-stayed span with a long floating section, making it one of the world’s most distinctive bridge designs. As you cross, the scenery opens into sweeping views of fjords, mountains and islands—classic Western Norway at its best. The bridge replaced the former ferry link and is today an essential connection between Bergen and the Nordhordland region, offering travellers both efficient transport and a memorable glimpse of Norwegian engineering and coastal beauty.

The Osterfjord is one of three fjords surrounding the island of Osterøy. The fjord runs along the municipal border of Lindås and Osterøy municipalities. The fjord begins at the Romarheimsfjorden and flows to the west for 27 kilometres (17 mi) before ending near the village of Knarvik at the confluence of four fjords: Osterfjorden, Radfjorden (to the north), Sørfjorden (to the south), and Salhusfjorden (to the west). The Osterfjorden is generally about 1 to 3 kilometres (0.62 to 1.86 mi) wide and the deepest point in the fjord reaches a depth of 639 metres (2,096 ft) below sea level

Canalized river with tidal water deep into the Osterfjord. The stream is about 600 metres long and between 50 and 60 meters wide at the most narrow place. Mostraumen was canalized (dredged) about 1913.
