A circular route through the Mené highlands, the summit of Mont Bel-Air and historic buildings give Trébry a distinct character for a getaway combining activity and heritage. The route length is the main consideration when planning: the “De Trébry au Mont Bel-Air” loop covers 14.5 kilometres, is rated moderate and takes about four hours.

Circular route through the Mené highlands

The starting point is the car park opposite Trébry town hall. Before setting off, check local trail conditions and whether parking is available. Knowing the approximate duration helps you plan the hike as the main focus of the day; you can factor in breaks as needed. The trail passes through the typical hilly landscapes of the Mené highlands, offering a practical way to explore the area on foot.

Small streams rise where the terrain slopes down along the route. The Gouëssant is one of them, beginning as a trickle. The trail also passes the Source de la Perchais, a quiet, green place to rest and picnic. The route thus brings together the varied landscape of the highlands and smaller waterways. For the views, look towards Mont Bel-Air: on a clear day, they stretch across the Pays de Penthièvre to the maritime horizon.

Mont Bel-Air and its chapel

Mont Bel-Air is in the commune of Trébry. At 339 metres, it is the highest point in the Côtes-d’Armor département. At its summit stands the Chapelle Notre-Dame du Mont-Carmel, also known as Notre-Dame de Bel-Air. It was built between 1855 and 1862 and is distinguished by its octagonal shape. Eight covered paths converge on the chapel. Its summit setting, architecture and views make it a shared historical and landscape landmark.

Churches and traces of history

Another point of reference in time is the Église Saint-Pierre et Saint-Paul, whose construction dates back to the 17th century. Inside are very old statues of the Virgin Mary, Saint Anne, Saint Maudez, Saint André and Saint Mamert. Together with the summit chapel, built between 1855 and 1862, the church represents a different period in the area’s architectural history.

The 19th-century Chapelle Saint-Maudez lies 200 metres off the loop; a spring and a calvary are located nearby. The Dolmen du Cas Rouge is also off the loop, 800 metres away. It is also known as “l’autel des fées” and “table de sacrifice”. The dolmen is a remnant of a tumulus and bears witness to collective prehistoric burials. The two distances distinguish how these historic sites are positioned in relation to the loop: Saint-Maudez is closer to the trail than Cas Rouge.

The Château de la Touche-Trébry, which is protected as a historic monument, is also part of the commune’s protected heritage. Trébry therefore offers a variety of points of interest: a moderate hike of about four hours, a summit chapel with distinctive architecture, and religious and prehistoric heritage.
