Arzon is said to be the French village with the longest coastal area in France. Arzon marks the east entrance to the Gulf of Morbihan.

There are two seaside resorts in the commune:

* Port-Navalo (Porzh Noalou), dating from the nineteenth century
* Le Crouesty (Ar C'hroesti), in constant development since the 1970s

Several hamlets are located on the territory of the commune: Monteno, Kerners, Béninze, Tumiac, Kerjouanno.

Arzon is a popular summer resort. In winter, fall and spring, only two "gendarmes" (rural French military police) work in Arzon, but in the summer there are far more to cope with the influx of tourists.
