Baie de la Fresnaye

Highlight • Beach

Located in the east of the Côtes d'Armor, on the Emerald Coast, the Bay of La Fresnaye is a foreshore of approximately 900 ha, favored for shellfish farming and in particular the cultivation of mussels and oysters. Its hydrographic perimeter is part of that of the SAGE Arguenon bay of Fresnaye, representing 20% of the surface of the latter. A flat and semi-enclosed bay, its relatively clear waters are a key factor facilitating the proliferation of green algae. Ulva type Ulva and other opportunistic algae such as Pylaiella littoralis are present and synonymous with the high trophic level of the bay.

Coast at Fort La Latte

Highlight (Segment) • Other

The coast at Fort La Latte is a walk that starts from Cap Fréhel and follows the coastal path (GR34) to Fort La Latte, a medieval fortress located on a rocky outcrop facing the sea. 6 km round trip, which offers magnificent views of the pink sandstone cliffs, the emerald sea, the flowered moor and the ornithological reserve of Cap Fréhel. Fort La Latte is a historic monument dating from the 14th century and has served as the setting for several swashbuckling films. It can be visited from March to November and allows you to admire the panorama of the Emerald Coast, Cap Fréhel and the island of Bréhat.

Cap Fréhel Lighthouse

Highlight • Monument

The lighthouse (32.85 m) rises impressively on the up to 70-meter-high cliffs of the Emerald Coast and is one of the most famous landmarks in Brittany. The current tower was built between 1946 and 1950 and still fulfills its important role as a navigational aid today. The observation deck offers an impressive panoramic view of the vast sea, the steep cliffs, and the offshore islands.

Access to the lighthouse is possible from 2:00 PM. For adults, admission is €3 per person.

Route Along the Bay of La Fresnaye

Highlight (Segment) • Trail

Small, pleasant coastal road towards Cap Fréhel, to avoid the main roads.
Passage in front of Nieux port then nice little climb towards Plévenon.

A great tour, mostly on back roads and bike paths. We walked a few kilometers at the fort and the lighthouse and cycled the rest. Good brakes are a must!
