Do you dream of a rugged coastline with turquoise waters, easily accessible by train, where you can enjoy a succession of iodized hikes and bike rides? Then you'll love the Côtes-d'Armor! Thanks to its 5 TGV stations (Lamballe, Saint-Brieuc, Guingamp, Plouaret, Lannion) and 32 TER stations, this corner of Brittany can be discovered without a car, to the rhythm of the salty wind and the tides.

Nature and itinerancy: pack your hiking boots. The mythical GR 34 - sentier des douaniers - links the stations of Saint-Brieuc, Paimpol and Lannion, skims the Côte de Granit Rose and winds its way to the coastal loop of Lannion. Need a more spiritual variant? The Mon Tro Breizh circuit invites you to walk from Plouaret to Paimpol, then from Paimpol to Saint-Brieuc, before continuing to Lamballe and Dinan, again from station to station. By bike, the Vélomaritime (EV4) links Saint-Brieuc to Dinan or Lannion, while two major loops, West and East, leave from Saint-Brieuc to cover a fascinating coastline.

Heritage & highlights: of the department's seven must-see sites, four are directly accessible by train (the medieval city of Dinan, the Bay of Saint-Brieuc, the enchanting Ile de Bréhat and the flamboyant Côte de Granit Rose). From Saint-Brieuc or Lamballe TGV stations, a bus will take you to the Grand Site de France Cap d'Erquy - Cap Fréhel for an XXL panorama. Five Petites Cités de Caractère® can also be visited by TER: Pontrieux the “little Venice”, Guingamp and its Gothic heritage, Châtelaudren nestling around its pond, medieval Jugon-les-Lacs and Léhon, a pearl nestling on the banks of the Rance.

As for your taste buds: after the effort, the comfort! Try a buckwheat galette overlooking the port of Paimpol, flat oysters from the Bay of Saint-Brieuc or a still-warm kouign-amann in Dinan (all washed down with a glass of local cider or chouchenn).

In short, whether you're traveling solo, as a duo or with your family, the Côtes-d'Armor offers you a “train + nature” interlude where rosy cliffs, picturesque villages and signposted footpaths come together all year round!
