You've reached one of Norway's great crossroads. Tyinkrysset sits at around 900 metres above sea level, where the E16 meets road 53 to Årdal and the Sognefjord. The name means simply "the Tyin junction" – Tyin being the large lake nearby.
This has been an important meeting point for centuries, where travellers between east and west Norway would stop before tackling the mountain passes. In the early days of Norwegian mountain tourism, the Norwegian Trekking Association built their very first cabin at nearby Tyin in 1869-70 – the beginning of the entire DNT network that now spans the country.
Today it's a small but well-equipped settlement. The Filefjellsenteret complex has a tourist office, petrol station, Joker supermarket, and Intersport shop for outdoor gear. Filefjellstuene offers accommodation and food. There's an EV charging station if you need it. For a place this remote, you can get most things sorted here.
Skiing
Tyin-Filefjell ski centre is right here, with the Tørrisheisen lift accessible from Filefjellsenteret. It's one of Norway's most snow-reliable areas, sitting between 900 and 1,300 metres – the season often lasts into May. The resort has 17 kilometres of prepared slopes and five lifts, with views towards Jotunheimen's peaks. Cross-country skiers have access to around 250 kilometres of prepared trails starting directly from Tyinkrysset.
