Roc Trévezel (alt. 384m) is the highest point of the Monts d'Arrée. A jutting, rocky escarpment, it reveals a vast panorama of this range of "Breton mountains" covered in moors. Stretching out to the north is Léon Plateau; in clear weather, you can see the Kreisker spire at St-Pol-de-Léon and, to the east, Lannion Bay. To the west, the end of Brest harbour can be seen, and to the south, St-Michel mountain, with, beyond, the dark line of trees of the Montagnes Noires.
