The largest of Norway's fjords, Sognefjord reaches 204 kilometers inland and branches off into smaller inlets and fjords along the way. At its widest, it is almost five kilometers across, and the cliff walls reach as high as 1,307 meters, making a breathtaking sight. The most popular way to visit the fjord is by boat, and fjord cruises and sightseeing tours are plentiful, many of which depart conveniently from Bergen. Tourists will also enjoy exploring the narrower branches like Naeroyfjord, a spectacular 17-kilometer stretch with cliff walls that are only 250 meters apart and tower more than 1,700 meters above the water. Another top destination is Fjærland, the region that houses Europe's biggest glacier, Jostedalsbreen, and the Norwegian Glacier Museum.
