A pink granite setting

Trégastel is a small seaside resort in the Côtes-d’Armor, next to Ploumanac’h, at the heart of the Pink Granite Coast. Its shoreline is cut into coves and beaches, lined with heaps of strangely shaped pink rocks formed by thousands of years of erosion. Depending on the light and the tide, the granite shifts from pale pink to coppery orange.

From Plougasnou, you leave Finistère via Lannion: about 55 km by road to a landscape completely different from our wild coastline. It is an ideal outing for a long day, combining beach, walk and visit.

Trégastel’s finest beaches

The town has a dozen or so beaches. Three stand out and are easy to reach from the centre.

Coz-Pors

The emblematic beach, surrounded by famous rocks: le Dé, le Tas de Crêpes, la Sorcière.

Grève Blanche

Fine sand and clear water, very popular with families.

Grève Rose

A lovely bathing beach, ideal at sunset.

Islets at low tide

Some rocks can be reached on foot: keep an eye on the tide.

Coz-Pors and Grève Blanche are lifeguarded in summer. Around Coz-Pors you will also find restaurants, kayak and paddleboard hire, and boat trips to the Sept-Îles archipelago. Before you go, check the tide times: the beach looks completely different at low water.

Île Renote, the aquarium and the customs officers’ path

Île Renote

Linked to the mainland by a causeway, Île Renote has become a peninsula. It is one of the finest sites on the coast: a field of pink granite boulders where you wander between the rocks, with the sea all around. The walk is easy and suits all ages.

The marine aquarium

About fifty metres from Coz-Pors, Trégastel’s marine aquarium is set right inside a jumble of granite boulders. It presents local marine life and how the tides work, with a touch pool that children love. The visit ends on top of the rocks, with a view over the coast. A safe bet when it rains.

The customs officers’ path

The GR34 coastal path runs along Coz-Pors beach and links Grève Blanche to Île Renote. Continuing east, it leads to Ploumanac’h and its lighthouse, one of the most famous stretches in Brittany. For a full day, combine Trégastel in the morning with Ploumanac’h in the afternoon.

The Sept-Îles

Offshore, the Sept-Îles archipelago is a nature reserve renowned for its seabird colonies, including gannets. Boat trips leave from Trégastel and Perros-Guirec, depending on the season and the weather.
