Tangafjørður Travel Guide
This is the southern part of the strait between the two largest islands in the archipelago Streymoy and Eysturoy.

The depth in the strait is 60 – 70 metres. The northern part of the strait is called Sundini.
The underwater tunnel Eysturoyartunnilin lies below the seabed under Tangafjørður. The tunnel reaches its lowest point 187m (613ft) below sea level.
