Trévou-Tréguignec is a municipality situated in the Côtes-d’Armor department of the Brittany region in northwestern France.
This commune is nestled within a valley, where it opens up to the expansive Trestel beach known for its pristine white sands. To the west, you’ll find the village of Trévou, while Tréguignec stands on the eastern shore. The Chateau of Boisriou is situated in this valley, surrounded by numerous ponds and a forest. The coastline in this region boasts a diverse landscape with unique rock formations. It stretches from the Le Groff harbor, adjacent to the Trélévern commune, to Port-du-Royau, near the Port-Blanc dunes.
Trévou-Tréguignec boasts two beaches: Royau and Trestel (or “Traezh” in Breton, signifying fine sand). Trestel, often recognized as a nude beach, has been a magnet for summer visitors and held the European Blue flag, symbolizing environmental excellence, from 1998 to 2004. The area is also home to a Thalassotherapy center. Another smaller beach has earned the nickname “Cabbage Beach” due to the Sea kale flourishing on its pebbly shores.
Trestel is a popular spot for windsurfing and even hosted the French funboard championship in October–November 1990.
