The Greenway - and the Percée Viaduct - a fascinating story, which can be read on the information panels and is very interesting to me. Here's a translation of Vaduz: Like elegant young ladies striding over the valleys of the Lilliputian kingdom, at the beginning of the 20th century, nine viaducts, including the Parfond de Gouët Viaduct, with their beautiful brick arches, stretched along the very first railway line of the local network, St. Brieuc - Plouha. These engineering structures, built by a native of the region, Louis Harel de La Noë (1852-1931), a bridge and road engineer, allowed the small train of the Côtes-du-Nord to follow the winding and steep coastline without much effort. Lightness and elegance are the words that come to mind when describing the architecture of this 1903 building, characterized by numerous columns and arched vaults and its masonry in warm brick colors. The techniques used demonstrate boldness, ingenuity, and originality: reinforced concrete anchors (rebars) were installed to increase the compressive strength of the pillars and prevent cracks.

In this case, you'd first drive there, then return via the GR34, which offers great views, and then cycle back to the car. This is at least convenient for the climb from the parking lot.

The area around Tréméven offers a good selection of traffic-free gravel bike trails. This guide features 4 routes, ranging from moderate to difficult, allowing you to explore the diverse landscapes of Brittany.
Tréméven's gravel trails offer varied terrain, from river valleys and dense woodlands to former railway lines. You'll find a mix of unpaved roads and paths, with elevations ranging from 3m to 97m, providing both engaging climbs and scenic descents. Routes in this guide are rated as moderate or difficult.
While the routes highlighted in this guide are rated moderate to difficult, the region of Brittany, including areas around Tréméven, features 'Voies Vertes' (greenways) which are often converted railway lines. These paths are typically flatter and more accessible, making them excellent for relaxed gravel biking and beginners. You can often find these by searching for greenways in the broader Finistère area.
For a longer adventure, consider the La Plomée Fountain – Chatelaudren Pond loop from Le Merzer, which spans nearly 95 km. Another substantial option is the Port of Binic – Parfond du Gouët Viaduct loop from Goudelin, covering over 82 km.
Yes, all the routes featured in this guide are circular, allowing you to start and end at the same point. For example, you can enjoy the Sentier Saint Jacques – Kapelle Saint Jacques loop from Tressignaux or the Saint Lawrence Chapel – Kapelle Saint Jacques loop from Plouha.
The region is rich in history and natural beauty. While cycling, you might encounter historical sites like the ruins of Château de Carnoët (11th century) or the Manoir de Kernault. For scenic views, look out for viewpoints such as Pointe de Plouha or Saint Barbara Chapel. The View over Bréhec – Picturesque little port loop from Pléguien offers coastal vistas.
Tréméven and the wider Finistère region are enjoyable for gravel biking throughout much of the year. Spring and autumn offer pleasant temperatures and beautiful scenery with changing foliage. Summer is also popular, especially in the shaded woodlands, though it can be busier. Winters are generally mild but can be wet.
For family-friendly options, focus on the 'Voies Vertes' (greenways) in the broader Brittany region. These former railway lines are typically flat, well-maintained, and free from vehicle traffic, making them ideal for families and less experienced riders. While specific family-rated routes aren't in this guide, these greenways offer a safe and enjoyable experience.
Parking is generally available in the towns and villages where these routes begin. For example, routes like the La Plomée Fountain – Chatelaudren Pond loop start from Le Merzer, and the Port of Binic – Parfond du Gouët Viaduct loop from Goudelin. Look for public parking areas in these starting locations.
The komoot community rates the trails around Tréméven highly, with an average score of 4.0 stars. Reviewers often praise the quiet, traffic-free nature of the routes, the diverse landscapes, and the opportunity to explore both river valleys and dense woodlands away from main roads.
While direct public transport to every trailhead might be limited, larger towns like Quimperlé, which is easily accessible, can serve as a base. From there, you might find local bus services or cycle paths that connect to the quieter gravel routes. Brittany's greenways often connect towns, making them accessible by public transport in some sections.
