Blaise (rivière) - Affluent de l'Eure walks

This circular loop in the Senonches State Forest, starting from the Grand Rond – a magnificent star-shaped junction of forest tracks – first follows long forest tracks leading to the Rond des Quatre Barrières and then to the Rond des Hussards. A path then winds its way between the state-owned forest and private woodland. After passing through the Rond de la Rachée, the route passes at the foot of the Chêne d’Hérissé, the sole survivor of the 1999 storm in this area. Shortly before the finish, the Hêtre du Haut Cornet stands a few metres from the path.

Let's go in search of the Blaise, a mischievous little river that hides so well from its source that geographers are perplexed. According to the elders, it originates near the Rond des Louvetiers, between Tardais and the Étang de la Bénette. Recent maps show it near the Grand Rond. In fact, these are "gouttiers", episodic streams that flow towards and cross the Tardais pond. It emerges under the dyke where a mill once operated, but suddenly disappears, sinking into a "chasm". It sometimes reappears. At the edge of the forest, the Ruisseau de Saint-Cyr joins it. Together, the two waterways pass at the foot of Louvilliers-lès-Perche, flowing sometimes on the surface, sometimes underground. The Blaise reappears definitively in the Étang de Dampierre. In the past, it enabled the establishment of a very important steel complex. It then flows towards Dreux, which it crosses, before joining the Eure at Fermaincourt.

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.

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.

Le Gué au Chéron is a district of the Senonches National Forest. This tour starts in Tardais and leads through fields into the forest. It follows the edge of the forest, passing in front of the majestic Chêne de la Framboisière oak tree. After crossing the old La Loupe-Verneuil railway line, the trail follows the Gervaine, a stream that was canalised in the 18th century to float timber down the Avre and Seine rivers to Rouen.The trail then runs alongside the Étang de la Bénette, managed by the Conservatoire des Espaces Naturels, which preserves its exceptional flora and fauna. A long forest line crosses the Rond de Sauveloup, then joins the small road from Tardais to Laudigerie. It takes you past the lake and the Château de Tardais before reaching this picturesque village with its wash house, small church and tiny town hall. Vlaminck stayed here frequently and immortalised this view of "the road" in winter under the snow from the town hall to the church in one of his paintings.

This circuit begins in the heart of the Senonches Forest on wide, easy-to-ride paths, starting from the Rond de Condé, followed by a passage through La Ferté-Vidame and its rich historical past.Don't miss Moussonvilliers and its washerwomen at work at the Ruisseau de Grenouille wash house.Afterwards, cross various waterways, each one different from the other, including the Rivière de Saint-Maurice, the Avre, the Iton, the Risle, the Cauche and the Sommaire, the most difficult to cross.

For this second stage, fromthe town hall in La Ferté-Vidame, the route leads to the park entrance. After visiting the part open to the public, you unfortunately have to follow the wall of the former Citroën test centre. It was the birthplace of the "deux chevaux", the "traction avant" and many other models. Enclosed by this 13 km wall, it is impossible to cross, so you have to follow the D941 and D15.The route then crosses an area of farmland and copses. It passes by some pretty, well-restored houses. At La Pommarié, it finally reaches the woods. The Allée du Maupas leads to the Senonches State Forest, which you will follow for a long time. We pass at the foot of two remarkable majestic trees to reach the Grand Rond, a majestic star-shaped crossroads. After the village of Tardais, the route returns to the forest and leads to the entrance to Senonches. It crosses the town via the recently renovated and flower-filled main street.

What if you were invited by the Duke of Saint-Simon, famous chronicler of the Court of Versailles, to celebrate his350th birthday in La Ferté-Vidame? Imagine being able to accept this unlikely invitation and spending a weekend on this two-stage loop that will take you from Senonches, through forests and farmland, to his "favourite residence". Since 1975, the Saint-Simon Prize has been awarded every September to a contemporary memoirist during the book festival. In 2025, it will be the50th edition and we will celebrate the 350th anniversary of the duke, who was born in 1675. Set off to explore his estate and the "Petites Cités de Caractère" (small towns of character) of Senonches and La Ferté-Vidame along long forest paths, ponds and country lanes. If you are unable to meet the duke and his beloved wife, the Maison Saint-Simon will tell you about his life and work. Visit the romantic ruins of the castle built by the Marquis de Laborde shortly before the Revolution in the park.

This first stage connects Senonches to La Ferté Vidame. Through the national forest, the route takes you to the village of La Framboisière, the Château de la Hézière, near which there was once a glassworks, and, via a long forest road, leads to La Puisaye. After skirting the Étang de Rouge, the path crosses farmland and arrives at La Ferté-Vidame, the stronghold of the Duke of Saint-Simon, famous chronicler of the court of Versailles. At the entrance to the park, in the Pavillon Saint-Dominique, home to the tourist office, the Maison Saint-Simon presents his life and work. A walk in the park allows you to contemplate the vast views, the ponds and the ruins of the castle of the Marquis de la Borde, which replaced the medieval fortress, the "favourite residence" of the memoirist, in the 18th century. Recently restored, the "little castle" once belonged to King Louis-Philippe, benefactor of the village. The classical-style Saint-Nicolas Church contains the tomb of the duke and his wife.
