Another Sunday stroll to tire out the kids and the dogs.
Oh yes, you can snack on a few corn kernels along the way. But don't forget to bring your pigs; the black pudding will be perfect, stuffed with apples and chestnuts!
If you want to see water and seabirds, cross the road to the beach without Leonardo but with its surfers.
If you want to see grass without water or birds, walk 10 km; you'll still pick up a few kilos of chestnuts. Take a nice warm nap in one of the observation posts. I still don't quite understand; maybe you have to come at night and hope to spot a cat lurking in the tall grass?
The icing on the cake was that I thought everyone respected the silence in bird protection areas, but no!
The scrubland surrounding the area was suddenly infested with dozens of hunters; imagine the excited dogs and horns blaring for over an hour! I know some who are still looking for birds, yes, yes!
Who are we kidding?

I was expecting to see marshes and ponds, but too bad the vegetation took over. A very interesting walk though, with varied scenery, woods, fields, beautiful Breton houses, ocean, dunes, etc. Crossing apple orchards with a cider house to visit along the way, unfortunately closed on the day of my walk. It's a good idea to download the GPX before you set off, so you don't have to wonder where the crossroads are. Lovely walk.

My friend and I discovered this tour by chance while out walking. We loved it. It's well signposted, with a variety of landscapes that are easy to follow. The time and mileage corresponded well to what we walked, at a leisurely pace. I'd recommend route no. 2 as a loop. There are two other routes in the area. We'll be doing them soon.

Beautiful ride in the Guideloise countryside.
A bit chauvinistic, but I love this route.
Well shaded and very easy.

Don't forget to visit the blockhouse; you pass behind it and don't realise that you can go inside and climb up to it from where you have a magnificent view.
Go into the observatory to try and see the birds on the Loch (it's on the left of the route after Quéverne, at a junction where you have to go right).
very nice walk

A very fine route on dry or slightly damp ground, but it must be trickier in winter...
At the start, don't hesitate to go around the small loch rather than immediately to the left, especially if there are birds!
Between points 3 and 4, at the level of the car park, there are a multitude of signs, so follow: GUIDEL PLAGES to avoid searching (and making mistakes...)
On the map, point 4 hides the crossroads where you should turn left towards TRIEC, do not follow GUIDEL PLAGES opposite!
Enjoy your walk!

Interesting route, but be careful if you turn right after the little Loch (broken track), it's a dead end, so we kept going and ended up in the marsh!

This is a very fine, well-marked walk with a wide variety of flora and fauna.

No particular difficulties in fine, dry weather.

We've done this walk several times, in spring, autumn and winter. The last time was at the end of January 2020, when it was sunny but rained.
We enjoyed the beautiful light, which varied according to the season, and the mix of countryside, marshes and sea.
The information panels are interesting and the route well signposted.
The only regret is that there was no longer a map of the route at the large car park near the coastal road. A pity for walkers who set off blind!

At the Orvoen mill, take the left-hand section of the road
towards Grande Soudraie
then, on the hillside, turn left to pass above the mill
