Ferry landings occur at Syðradalur, and one of the mail boats (named Sam) makes regular trips from Klaksvík to both settlements.
One can walk north all the way to the lighthouse at Kallur but the four unlit tunnels on the way make  carrying a torch advisable.
Traffic is insufficient to pose problems with exhaust gases.
The northernmost tunnel through to Trøllanes is narrow, cold, damp, and over 2 km long.
 It is rarely used by vehicles since the population of Trøllanes is only 20.
The alternative overland route from Mikladalur to Trøllanes is a dangerous and precipitous path that is best avoided.

Bus service between Húsar and Trøllanes also is provided.
