The fjord reaches a maximum depth of 1,308 m below sea level. The greatest depths are found some way inland: near its mouth, the bottom rises abruptly to a sill about 100m below sea level. The average width of the main branch of the Sognefjord is about three miles. Cliffs surrounding the fjord rise almost sheer from the water to heights of 1000m and more.
Boats connect settlements along the fjord and its sidearms. Towns on the fjord and its branches include Balestrand, Gudvangen and Flåm. Flåm is situated on Nærøyfjord (Narrow Fjord), a branch of the Sognefjord particularly noted for its unspoilt nature and dramatic scenery ([1] (http://www.sognefjord.no/fjord/naeroyfjord.asp)), and only 300m across at its narrowest point. From Flåm, the famous Flåmsbana railway climbs 900m up to Myrdal in only 20km, in the steepest unassisted railway climb in the world.
Nærøyfjord
Over the Sognefjord a power line with a span of 4597 m is installed. This is the second largest span of power lines in the world.
