Trongisvágur is the village in the bottom of Trongisvágsfjørður (fjord) on the east coast of Suduroy.

A river called Stórá that runs through the valley passes through a plantation that is worth visiting on a good day, and then flows into the inlet at a nearby beach.

There are binoculars there in summertime, so people can have a closer look at birds and the vertical cliffs there.

[2] The highest mountain in Suðuroy, Gluggarnir, is in the south of Trongisvágur; it is 610 metres high.

On 17 November 2011 they started to build a new football stadium for TB Tvøroyri west of the sports hall.
