Tórshavn - Oyggjarvegur - Kollafjørður - Tórshavn
From Tórshavn central bus terminal you follow the roads Yviri við Strond and Eystari Ringvegur, then turn right into Oyggjarvegur a bit further up.
This route has steep ascents and descents, but hardly any cars, so you can go at full speed down the hills while you admire the views of the sound and fjord.
At the mountain pass of Norðadalsskarð you have two choices. Either turn left and cycle down to the village of Norðadalur. For this option you must be fit, as the return route climbs up of the steepest hills in the country. Alternatively, you can cycle up the mountain of Sornfelli, from where you have a view of most of the islands in the Faroes.
Return to Oyggjarvegur and continue to the mountain of Skælingsfjall, which is 763 metres above sea leave. You then carry on down to Kollafjarðardalur.
On the return trip to Tórshavn you pass through the tunnel to Signabøur, and you then follow the roads to Kaldbaksvegur and Hvítanesvegur into town.
