Tréon walks

A lovely circular walk, mostly along departmental roads, but also featuring trackways through the fields and, finally, paths through the woods. The walk around the Étang d’Écluzelle is magnificent, offering the chance to spot a variety of birdlife.

This family-friendly route takes in the sites associated with Madame de Pompadour, mistress of King Louis XV, who lived in Crécy-Couvé in the 18th century.

Dreux, the old town with its medieval castle fortifications, narrow streets, belfry, Royal Chapel of Saint Louis, half-timbered houses, ramparts, not to mention its vineyards, etc. Everything you need for a wonderful day out with the family.

Starting from the public garden created by the local council around the Torçay pond on Rue de la Blaise, this short circular route takes you through the beautiful Blaise Valley, passing the recently restored Church of Saint-Ange. It then follows the pond created from a former gravel pit dug in the 1960s, near the Torçay mill. Although highly controversial at the time due to the risk of groundwater pollution, these bodies of water now add to the charm of the valleys in the Drouais region. The numerous mills that line the valley, bearing witness to a very early industrialisation, have now become beautiful private residences, such as the Torçay Mill. The scenic value of the area justified retaining the detour required by the new GRP® route, which has replaced the former GR®351, before heading towards the Châteauneuf forest.

Set off to explore the limestone hillsides overlooking the Mézières-Ecluzelles lake, the Pierre de Pucre dolmen, and the unspoilt flora and fauna of this departmental nature reserve.

A circular route starting from Saint-Jean-de-Rebervilliers. Largely through woodland, it leads to Châteauneuf-en-Thymerais. After setting off through the forest, the route crosses the Rond de France, where a beautiful stone column stands, locally known as the ‘pyramid’. After passing through the town centre, the return route takes you back through the forest, past the Château du Jaglu and then the Église Saint-Jean, ending near the pretty pond with its pleasantly landscaped surroundings.

A circular route starting from Saint-Sauveur-Marville, heading towards Châteauneuf-en-Thymerais through the fields, then returning via the forest past the Château du Jaglu. This route, situated on the border of the Thimerais and the great Beauce plain, will be particularly appreciated by lovers of wide open spaces and sweeping horizons.

This circular route offers an opportunity to discover some of the structures that line the Avre Aqueduct, particularly the Tue-Cheval structure, but also to admire the castle of Escorpain. Two pretty ponds are also on the itinerary. It is an easy route with a few sections in the forest, which are welcome when it is very hot!

A lovely walk around Ouerre and its hamlets. Places of interest along the way (among others): the Morainville Calvary, the former vicarage, the Church of Saint-Cyr-et-Sainte-Julitte, ‘la Grimpette’ (the Schoolchildren’s Path), Prémont Castle, and the dolmens in the Bois de Brasée.

This is an easy route, the second part of which is very pleasant in hot weather as it follows the banks of the Avre on theGR®®22. There are various places to stop and picnic by the water.

This walk, in the Dreux Forest, offers a beautiful view of the village of Montreuil, the Eure Valley and the arches of the Eure siphon, the Avre aqueduct that supplies drinking water to the city of Paris. Come and discover a walking route in the Dreux National Forest; after a bit of exercise, you’ll climb the hillside along a very pleasant path, having crossed the bridge over the Eure.

Route in the Châteauneuf-en-Thymerais National Forest

This circular walk starting from Chappe takes you on a journey of discovery through the Châteauneuf Forest. This hamlet has a pond that has just been restored and a magnificent oak tree. The route follows a section of the GRP® Vallées de la Blaise et de l'Avre from the Châteauneuf water tower to the Rond du Roi, then part of the bridle path that circles this vast national forest.

This circular route, suitable for all, circles part of the Dreux Forest, sometimes along well-marked forest tracks, sometimes along the edge of the hillside above the Eure Valley, whilst avoiding any significant changes in elevation, and passes through some of the forest’s most characteristic spots.

Halfway between the national forest and the hillsides of the Eure, this walk will take you to some remarkable places in the shade of oak trees and the coolness of the riverbanks. You will walk past the castle and through the old village of Sorel, then follow the old railway line (greenway) to Marcilly-sur-Eure.

Circular starting from Berchères la Maingot. Discover the remains of Louis XIV's unfinished canal, which was intended to supply the Palace of Versailles with water from the Eure. Dogs are allowed but must be kept on a leash.

Digny is located on the border between Perche and Thimerais. This route through the fields starts at the foot of the bell tower of Saint-Germain Church, built in 1525 and recently beautifully restored. In 2025, a local association organised various events to celebrate the500th anniversary of its construction. The route takes you to the 16th-century Ferme du Romphaye farm and the Château de la Hallière castle, built in 1770. The return journey takes you through the hamlets of La Richardière and Bellandas, allowing you to return quickly to Digny or extend your walk to Mille Champs along paths offering beautiful views of the village.
