Worth a visit

Saint-Martin-des-Champs

Saint-Martin d'Elleville Church. Originally, the area had two chapels, one dedicated to Saint Martin and the other to Saint Prix, located in Elleville. In the mid-16th century, the Le Coq family settled in Corbeville and chose the nearest chapel, Saint-Martin, to become the parish church under the name of St-Martin d'Elleville. Probably remodelled in the 16th and 17th centuries, this barn-like church has an "Avrais" style bell tower entirely covered with slate.

Corbeville Castle. Built in the 16th century, this building belonged to Lord Lallemant Lecoq, then, more recently, to fashion designer Jacques Fath (buried in the park in 1954) and singer Gérard Lenorman.

Two Dragor pumps. Created by Henri LEGOU in Le Mans in 1919, who founded Ets. DRAGOR & ALMA (DRAGOR – bucket pump and ALMA – compressed air pump), DRAGOR pumps were installed in place of wells or hand pumps as they were much less tiring to use and could reach depths of several tens of metres. They were operated by a crank handle, sometimes with an additional wheel on the opposite side.

Osmoy

Old drinking trough

Saint-Cloud Church. Dating from the 18th century, it is a simple barn-style church with an "Avrais" bell tower and a slate roof. Open only on Sundays

Notre-Dame de la Pitié Chapel. This sanctuary was already frequented in the Middle Ages. Even 40 or 50 years ago, the inhabitants still remembered the pilgrimages organised to Osmoy. The small chapel was restored around 1970. It was the destination of a pilgrimage where the faithful came from far and wide to venerate the statue of Our Lady, a 15th-century polychrome wooden statue.

A lovely walk at the start of spring! Thanks for the suggestion 😉
The section between Elleville and Saint-Martin, right at the end of the route, is practically a relaxation session, it’s so peaceful!
For those interested in extending the route (by about 9 km): Osmoy serves as a junction with another walk available on the app called "La plaine de Ferranville", which is just as lovely and picturesque 😉
Enjoy the walk, everyone

Very pleasant and easy hike in beautiful weather, with a refreshing breeze.
Variety of landscapes and places. Woods, fields and meadows, hamlets
Well-maintained paths, even around point 8!
We started at 1:30 p.m. and only encountered one quad bike...

What can I say about this? That this gentleman is not a hiker, but only a walker who has got the wrong subject.
I repeat that this route is perfect and fortunately less frequented than the THOIRY park; a park that can be visited with pleasure when the subject is coherent.
Happy hiking or walking to you all ......
Yours faithfully

Good evening, michel.gordin
I read your comment at the end of May. I went back with some real hikers to do this walk on 4 June. It is as accessible as it was when I created it. Only the sunken path might be unbearable for you. According to IJPA's comment on 4 May, it still was: "We didn't meet many walkers, but the paths are well maintained and are certainly used."
Nature reclaims its rights when it wants to, and farmers who maintain the paths adjacent to their plots are prohibited from mowing fallow land before June in the Yvelines (to allow game to reproduce).
Furthermore, you could show a little gratitude to the Visorandonneurs who publish hikes on a voluntary basis.
Finally, I quote you: "the worst hike we've done since we started using Visorando."
You have been registered on Visorando since 2016 and have only posted 10 comments, which are often unfriendly. And of course, as an assisted "hiker", you have not suggested any hikes...
What reassures me is that my hike isn't the worst... you gave another one three DECEIVING ratings!

A dreadful end to the walk from Osmoy (mark 7) on unkempt paths with grass that reaches halfway up your thigh.
the worst walk we've done since we started using Viso rando.
In fact, we're just confirming a fact already mentioned in a review dated 21 April 2025.

We didn't encounter many walkers, but the paths are well maintained and are certainly used frequently.
Well done on the accompanying document.
