About us

Cycling is a great way to get around Iroise. It's an original way to discover sites that have marked the history of our Pays d'Iroise! Listen to your desires and set off on an adventure on the signposted circuits that will take you through many of our region's communes.
4 bike circuits guide you through the countryside or along the Pays d'Iroise coast (An Envor circuit, Ar Mor circuit, An Avel circuit, Al Lenn circuit).

Along the way, take the time to put your foot down and read the heritage interpretation panels.

"Al Lenn" is signposted in both directions.
This circuit is divided into two loops, which can be done separately or consecutively.

A few rules of safety and good conduct:
- Before setting off, check the condition of your bike and take along a repair kit
- Respect the highway code: ride in single file, wear a mask: it is compulsory for children under 12 (CSIR of 02/10/15).
- Always take a snack and a drink with you
- Respect private property
- Don't litter, respect nature by using the garbage cans
- Please note: bicycles are not allowed on the coastal path.

For more circuits, visit the Iroise Bretagne Tourist Office, where mountain bike topoguides are available.

Step 1/6:

Start: Place Docteur Guyader parking lot, Saint-Renan.

The Prairie Bleue, a new green space, is crossed by the Aber-Idult river. The trail offers explanations of the valley exploited by the Saint-Renan mining company.

This washhouse on rue de la Fontaine is not the only one in Saint-Renan, but it is the largest. There are 3 others in the town center. Laundries are buildings of heritage interest.

Lavoir de Saint-Ronan

Between 1960 and 1975, thanks to the discovery of large ore deposits in the marshes bordering the Aber-Idult river, Saint-Renan became Europe's tin capital. Alluvial deposits of cassiterite, a stanniferous ore, were mined by COMIREN (Compagnie minière de Saint-Renan) using a cutter suction dredger placed on a floating pontoon (over 5,200 tons of 74% tin concentrate were produced).

Lake Comiren

The banks of Lac de Tréoualen (or Lac de La Laverie) are highly varied, with over 50% of branches and trees in the water. There are deep areas and very irregular bottoms.

Beautifully renovated, this residence combines historic cachet and comfortable modernity, XVIth-XVIIth-XVIIIth century.

The Cimetière des Saints is an enigma: it is thought to be the burial place of Christians from the tribe of Saint Rivoaré, who were massacred by pagans in the 5th century.
