One of the most beautiful beaches on the Pink Granite Coast.

Saint-Guirec beach is picturesquely situated among the pink granite cliffs of the Côte de Granit Rose (Pink Granite Coast). Highlights include the Saint-Guirec Oratory on the beach with its marriage legend, a small chapel nearby, the Château de Costaérès offshore, and the GR34 coastal hiking trail, which runs directly along the beach and offers spectacular views.

The fine sandy beach slopes gently into the turquoise sea, inviting you to linger. At low tide, a fascinating mudflat area is revealed. On the shore stands the small oratory of Saint-Guirec, a chapel to which pilgrims have flocked for centuries to pray for the safety of sailors or to seek a husband. The stone statue standing there today dates from 1904.

The Chapel of Saint Samson was built in two phases, between 1575 and 1631. It is the main element of a complex, combining the manor house (to the south), which was once accessed, the fountain (to the northwest), the entrance gate (to the northeast), and the Christianized menhir (moved to the foot of the porch). The first phase, completed in 1575 (a date previously visible on a buttress of the gable), concerns the chapel itself (without the tower), a small Flamboyant Gothic building with a superb ornate door to the south (then the only access point to the interior of the building) and an apse intended to later house a painted stained-glass window. This foundation is believed to have been initiated by the lord who owned the Barac'h-Keruzec fief, who endowed this isolated territory with a Christian building, providing a rhythm for the peasants' lives. A second phase, completed in 1610 (date visible on a window), concerns the construction of a western massif, with an entrance porch and a bell tower composed of a square tower flanked by a spiral staircase turret, surmounted by a dome. This achievement is inspired by the Beaumanoir style, developed during the previous century in the lower Trégor, from Morlaix to Lannion, very appreciated for its elegance and characterized in particular by a slender bell tower-wall.

The roof table measures 5.75 m long, 3.55 m wide and 0.75 m thick. The orthostat on the north side measures 2 m high, 1.50 m wide and 0.20 m thick. It continues to the west with a dry stone wall which does not appear to be original. The orthostat on the west side is slightly domed. It measures 2.55 m wide by 2.305 m high with a thickness between 0.40 m at the base and 0.30 m at the top. The southern orthostat is backed by the slope. It measures 2.50 m wide, 2.40 m high and 0.35 m thick. The internal chamber measures 5 m long by 3 m wide with a height under the slab of 2 m

A very beautiful sandy beach with clear water. The surf is quite gentle here. There's a beautiful view of the Château de Costaérès.

Beach in the municipality of Trégastel on the Pink Granite Coast in Brittany, France. The beach is known for its proximity to the Trégastel market, which takes place every Monday morning and offers local products such as fish, seafood, fruit, and vegetables.

Located 1 km from the town centre of Perros-Guirec, Trestrignel Beach offers holidaymakers a stretch of fine white sand. Protected from east and west winds, Trestrignel Beach is surrounded by Pointe du Château and Pointe du Sphynx. Its wild side contributes to the undeniable charm of this beach. On a clear day, you can enjoy the panorama of Tomé Island and the Sept-Iles Archipelago.
