Frošba is located farthest out on the north brink of Trongisvagsfjųršur-inlet on the east coast of Sušuroy.
The village has eventually merged with the nabour-city of Tvųroyri.
Tradition says that Frošba is the oldest village on Sušuroy. A danish king, Frode, floated on-shore and settled here. The place is named after him.
In Frošba some funny looking stoneformations of Columnar Basalt can be seen. They are 10 meter high columns with six edges.
'Frošbiarnķpa' a 324 meter high cape rises behind Frošba. A small road runs from Frošba to the top so it is possible to walk up there and enjoy the amazing view over the sea and the inlet.
Below Frobiarnķpa there is a cave called 'Hol i Hellu'. This means 'Cave in the massif'. Following the stone-beach leads to this cave. You will have to climb a litle bit though. On the way to the grotto a layer of coal can be observed in the massif. This coal is what is left of the woods that covered the area 50 millions years ago. The woods were covered by lava from later vulcanic eruptions.
From the shore at the bottom of the grotto huge rocks can be seen in the water. These were part of the roof of the cave.
