Small isolated building in the place called Villieu (former islet in the heart of the Bourgoin marshes), consisting of a small nave lit by a bay on each side and extended by an apse with a lower height than the nave. The facade is pierced by an entrance door surmounted by a basket-handle lintel bearing the inscription 1893 / NOTRE DAME DE VILLEU. https://recensement.patrimoine-religieux.fr/eglises_edifices/38-Isere/38415-Saint-Marcel-Bel-Accueil/150630-ChapelledeVillieu

Beautiful cycle path, mostly shaded, unpaved but rideable (I ride it with 23mm tires), which follows the old line of the Chemin de Fer de l'Est Lyonnais (CFEL)

Nice Sunday morning Gravel ride. Arrived at 8 am in Miribel park, not a soul 🐈⬛ but a few hares and signs waking up quietly near the many beaches. I'm surprised by the quality of the singles and trails which are super well maintained. Would gladly do it again.

The terrain around Grenay is distinctively shaped by its mining history, featuring 'terrils' (slag heaps) and 'fosses' (former mining pits) that have been reclaimed by nature. You can expect a mix of challenging ascents on these artificial hills, offering panoramic views, and smoother sections through forests and greenways. The broader Hauts-de-France region also provides varied plateaus, ensuring a diverse gravel biking experience.
Yes, several routes are suitable for families. A notable example is the "Grenay à vélo et sa balade entre fosses et terrils" route, which is described as a pleasant loop with very little asphalt, making it ideal for gravel bikes and families. While we don't have specific family-friendly routes in our current selection, many of the no-traffic paths are generally accessible. For a moderate option, consider the Crémieu, medieval town – Château Delphinal of Crémieu loop from Mianges, which offers a manageable distance and elevation.
The trails often lead through the unique 'terrils' and 'fosses' landscapes, offering historical insights into the region's mining past. Beyond the immediate trails, you can explore nearby attractions such as the historic Château de Fallavier, the serene Lake Saint-Quentin-Fallavier, or the Marsa Pond Sensitive Natural Area. These offer opportunities to combine your ride with cultural or natural exploration.
Yes, many of the no-traffic gravel routes around Grenay are designed as loops, allowing you to start and end at the same point. This is convenient for parking and planning your day. For instance, the Pont de la Bourbre – View of the Col de l'Éperon loop from La Verpillière is a moderate circular route that offers scenic views.
The area is highly rated by the komoot community, with an average score of 4.7 stars. Reviewers often praise the unique historical landscapes, particularly the 'terrils' and 'fosses', which provide both challenging ascents and panoramic views. The low traffic nature of the trails is also a significant draw, allowing for a peaceful and immersive outdoor experience.
The Hauts-de-France region, where Grenay is located, offers pleasant cycling conditions from spring through autumn. Spring brings blooming nature, while autumn provides beautiful foliage. Summer is also suitable, but it's always wise to check local weather forecasts. The varied terrain means some paths might be muddy after heavy rain, especially in wetter seasons, so consider your tire choice accordingly.
While many routes offer moderate to difficult challenges, there are options for beginners. The "Grenay à vélo et sa balade entre fosses et terrils" route is specifically mentioned as being 'without difficulty' and 'doable with family'. For a slightly longer but still manageable ride, the Crémieu, medieval town – Château Delphinal of Crémieu loop from Mianges is rated as moderate and could be a good step up for those gaining confidence.
While the no-traffic routes themselves focus on natural and historical landscapes, Grenay and nearby towns offer various amenities. It's advisable to plan your route to pass through or near these towns for refreshment stops or accommodation. The broader Pas-de-Calais region has a good network of services, so a little pre-planning can ensure you have access to cafes and places to stay.
Due to the presence of 'terrils' (slag heaps), you can expect some significant, albeit often short, climbs. These artificial hills provide challenging ascents and rewarding panoramic views. For example, the Jonage Canal and Grand Large – Le Grand Large loop from Lyon-Saint-Exupéry TGV, while longer, features over 1000m of elevation gain, showcasing the potential for varied topography in the region. Even shorter routes will offer undulating terrain, making for an engaging ride.
Generally, dogs are welcome on many outdoor trails in France, especially if kept on a leash. However, specific rules can vary depending on the exact location, especially in nature reserves or protected areas. It's always best to check local signage or specific route descriptions for any restrictions. Many greenways and forest paths are usually dog-friendly, making them a good option for cycling with your canine companion.
