Departmental Route 2 road connects Tréogat with Plonéour-Lanvern and Pont-l'Abbé to the south west, and Pouldreuzic and Plozévet to the north west. The commune reaches the Atlantic coast at the Plage De Treogat in the Bay of Audierne. In addition to the main village of Tréogat, the commune consists of a number of hamlets.
Connected to Trunvel lake by a man-made canal is the Étang de Kergalan or Kergalan pond of 116 hectares (0.45 sq mi), divided between the communes of Tréogat and Plovan. The invasive water primrose, Ludwigia uruguaynensis, viewed as a threat to native aquatic vegetation has been found here and uprooted.[4]
