Mountain bike trails in Réserve Naturelle Des Sept-Îles are not found within the protected archipelago itself, which is a crucial bird sanctuary with insular, rocky geography. However, the surrounding mainland areas, particularly along the Pink Granite Coast, offer diverse mountain biking opportunities. This region is characterized by its distinctive granite rock formations, coastal paths, and varied terrain, providing routes that range from gentle coastal rides to more challenging inland trails.

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.

No, mountain biking is not permitted within the Réserve Naturelle Des Sept-Îles itself. This area is a highly protected marine bird and seal sanctuary, and its insular, rocky geography is not suitable for mountain biking. The focus of the reserve is on wildlife observation and conservation.
While the reserve itself is off-limits for mountain biking, the surrounding mainland areas, particularly along the Pink Granite Coast (Côte de Granit Rose) near towns like Perros-Guirec and Trégastel, offer numerous trails. Komoot lists over 30 mountain bike routes in the broader region.
Yes, the region offers several easy mountain bike trails. For example, the Étang des Cygnes loop from Phare de Mean Ruz is an easy 15 km route. Another family-friendly option is the Saint-Guirec Beach loop from Phare de Mean Ruz, also around 15 km.
Trails in the surrounding area, particularly along the Pink Granite Coast, often feature a mix of coastal paths, forest tracks, and some paved sections. You can expect varied terrain with some elevation changes, offering scenic views of the sea and the unique granite rock formations.
Yes, many of the mountain bike routes in the area are circular. For instance, the Étang des Cygnes loop from Phare de Mean Ruz and the Saint-Guirec Beach – Tourony Beach loop from Phare de Mean Ruz are both excellent circular options.
