The Orne around the Gros Banc

A birdwatching site of great beauty, the bay of the Orne estuary is now protected by the Conservatoire du Littoral. The Maison de la Nature, several observatories and a network of footpaths showcase this unmissable natural area.

Description of the walk

Access: from Caen, head towards Hérouville and Ouistreham (D515). Exit towards Bénouville and Merville-Franceville until you reach Pegasus Bridge. Cross the bridge and continue for 3 km towards Merville to reach the Maison de la Nature et de l'Estuaire in Sallenelle, where you can park.

(S) With your back to the Maison de la Nature et de l'Estuaire and facing the bay, turn right and follow the small road along the path towards Merville.

(1) At the Restaurant de la Baie, turn left onto the path still towards Merville (go under a gate). Continue along the bay until you reach the road (D514). Follow this road on the left for about 200 metres.

(2) At the crossroads, take the second path on the right to reach the bay observatory. From the promontory, don't miss the view of the bay and its birds.

(3) Take the path along the road and, when you reach Merville, turn immediately left onto the bay path towards the water sports centre.

(4) At the car park of the old Redoute (orientation table), continue along the small road to the left or take a short detour through the dunes.

(5) Join and cross the water sports centre until you reach the Transat bar, which offers an exceptional view of the bay and the Ouistreham lighthouse on the other side of the Orne. Continue to the right on the path that follows a stone dyke. Walk along the beautiful sandy beach opposite the Pointe du Siège for a good kilometre.

(2) Once you are back near the road (D 514) but before reaching it, turn right towards Sallenelle to take the path you took on the way there in the opposite direction.

(1) At the Restaurant de la Baie, turn right to return to the car park at the Maison de la Nature (S/E).

A short, easy walk with no difficulties.
Best done when it hasn't rained too much, as some sections can be muddy.

An easy and pleasant route with beautiful marshland scenery and birds. The trail was deserted when we did it in the morning and easy to walk two hours after high tide.

Nice route.
The Restaurant de la Mer no longer exists, and at the nautical centre, the bar is no longer called Le Transat, but La Réserve.

We did the walk at around 1 p.m. There wasn't much shade and too many cyclists rode past without paying any attention to the walkers. Otherwise, it was very interesting if you brought binoculars. On the way back, it was high tide, so we had to wade through the water. Allow 2½ hours if you're interested in wildlife. I'll go back in autumn when the holidaymakers have gone and the birds start migrating again.

Good hike, pleasant but a lot of cycling on the residential part of the park before the reserve loop.
Few birds but beautiful marshland scenery.

A lovely walk on a weekday, so not too crowded.
Description needs updating: the Restaurant de la Baie no longer exists. Check the tide times: at high tide, part of the walk is in the water.

We did this trail in rainy weather and at high tide. It was superb and easy. However, on the way back, we had to take off our shoes to wade through the sea water along the beach. It was quite cold, but the 50 metres in the water prevented us from turning back.
Thank you for this beautiful hike.

Thank you for this first hike with my dog. Everything was perfect, and as I was travelling alone, I felt reassured being able to share my progress with my partner.

Nice walk, beautiful views of the large sandbank. We did hesitate once or twice about whether to turn there or further on. And it should be specified that it should be done at low tide (which was the case for us), as is it passable all the way around the large sandbank at high tide, especially if the tidal range is high?

Hello,
The route and description need to be changed. Work is currently underway to restore water to the
François site, and it is no longer possible to take the path on the left, opposite the former café restaurant. At present,
The cycle path remains open while work is ongoing
