A walk around Tascon Island

Make the most of low tide to walk around the tiny island of Tascon, which is linked to the mainland by a submersible road. Spend a few hours feeling as though you’re in a little world of your own, walking along the foreshore facing the tranquil waters of the Gulf of Morbihan and its countless islands.

Description of the walk

Whether you’re coming from Vannes or Sarzeau, Île Tascon is very well signposted near Saint-Armel or Lasné. Within the village of Lasné, follow the signs for “Île Tascon” to reach the start of the submersible causeway leading to the island.
There is a large car park for cars, with a height restriction of 1.90 m. Another car park is reserved for motorhomes – free during the day and subject to a charge (€5) at night.

(S/E) As soon as the ebb tide has cleared the causeway, head towards the island.

(1) On arrival on the island, leave the tarmac road and head onto the foreshore. Sandy patches make walking easier there, between the rocks and the piles of seaweed.

(2) When you reach the hamlet of Tascon, you can either continue along the foreshore or opt for a stretch of road – which is the route suggested here – to explore the interior a little, notably the hamlet where, amongst other things, you’ll find the Ferme de Tascon, which sells local produce. If you choose the road, follow it to the end.

(3) Head down onto the beach and turn right towards the northern tip of the island. Pass this headland and continue along the beach towards the south-east. After a long walk along the beach, you’ll reach a cove bounded to the east by a sandy headland.

(4) Beyond this, you can continue along the beach to the southern tip of the island, where you’ll rejoin the access road. Here, you have the option of taking a grassy path that leads out onto the beach and takes you to the hamlet of Tascon, then take the island’s main road heading south.

(5) When you reach this three-way junction, take the left-hand road which heads across the fields and soon turns right at a right angle before joining the main road.

(1) Head back along the road in the opposite direction to return to the car park (S/E).

Notes

It’s a very easy walk and can be done in trainers or even sandals. Do, however, take care on sections where the rocks and seaweed may be slippery.

Of course, it is essential to check the tide times. It is best to set off on this walk as soon as the path has been cleared by the ebbing tide if you want to enjoy long hours of walking on the island and along the foreshore.

Worth a visit

Just off Tascon Island, you might want to venture as far as the tiny island of Enézy out of curiosity.

Furthermore, to the south, you can visit the Ludré marshes, former salt marshes that have become a nature reserve, which can only be circumnavigated from inland.

Another lovely walk is the route to the Passage Peninsula (Saint-Armel), following the dykes alongside the former Lasné salt marshes, another protected wetland that is vital for biodiversity.

A round trip along the western part of the island; it should be noted here that, under a biotope decree, Corn Bihan Cove, situated to the east of the island, is a protected area designated to allow birds to rest. Environmentally-conscious walkers should therefore turn back and enjoy the view from the shores of Saint Armel. Furthermore, there is no pedestrian access to the submersible causeway situated in the south of the island, unless you cross private property. Nevertheless, I highly recommend sampling the local cheeses produced by the island’s lodge.

Walking across the scree on the beach requires caution. At point 4, a sign prohibited continuing along the shore (bird sanctuary) and the grassy path leading to the village was not visible.
On the way back, crossing the ford requires EXTREME CAUTION. In our group of 24 people, two fell violently on this extremely slippery surface.

The end of the island walk is made more difficult by the challenge of finding the path, which is very well hidden and not clearly described in the guidebook.
Pay close attention to the tide times and, above all, take care when crossing: the path is slippery!

Sorry, I can confirm that it is indeed in point 4.

To ensure your comment is constructive, it would be helpful if you could specify exactly where you encountered difficulties. I imagine it’s in point 4? You’d still need to clarify that, though.

We couldn’t find our way back. We had to climb over a mound of earth and crawl under electric fences twice. Disappointing

We’re from Vannes but discovered this short walk thanks to Visorando.
It was lovely, with beautiful light and a real island atmosphere.

It’s true that I’m a “loyal son of the Ardèche” living in the Gironde, but I’m still very attached to my home region and my house back there, perched on top of a rocky outcrop. It’s a steep climb.
We really enjoyed our five days around the Gulf. We cycled round the island of Tascon just before heading back to Bordeaux, and it was lovely to finish off with that little ride.

@Ardechois33 (alias, perhaps, “Ardéchois Cœur Fidèle” – a reference to a famous TV series from days gone by!), do you think that climbing the stepped paths through the steep chestnut groves (so dear to Jean Ferrat) isn’t a bit of a slog?
I’m joking, of course, but we’re all-terrain walkers, and every setting has its own charm that has to be earned.
I hope that, during your walk, you still managed to breathe in the fresh, sea-scented air of the Gulf of Morbihan.
Thanks for your feedback anyway.

It’s mainly worth taking the submersible road
Walking along the foreshore is quite a slog, but it would be a shame not to go there
