Route of Tréguennec beach and its vast dune area

After passing the remains of the pebble crusher – a reminder of the construction of the ‘Atlantic Wall’ – walk for about 3 km along the beach overlooking Audierne Bay.
Continue through the palud, a transitional zone between the dunes and the marshy areas which are heavily flooded in winter.
There are some lovely heritage sites to discover along the way: the hamlets of Le Stang and Saint-Vio, the latter restored for the Maison de la Baie d’Audierne, as well as two charming chapels, each set in its own unique surroundings.

Description of the walk

Access: on leaving Plonéour-Lanvern towards Plozévet, at the cemetery, turn left onto the D156 towards Tréguennec. Drive through the village and continue along the Route de Saint-Vio. Before the chapel, at a junction of small roads, turn right towards the sea onto the Route de Prad ar C’Hastel or Prat ar Hastel until you reach the imposing remains of the pebble crusher.
The car park is on the left.

(S/E) With your back to the car park, head north-west, passing between the remains of the pebble crusher used in the construction of the ‘Atlantic Wall’. Admire the murals decorating it. At the end of the last building, go up the ramp on the left leading to the beach, down which you then descend.

(1) On the beach, turn left towards the south-east and begin a long walk of about 3 km. Pass afirst group of blockhouses that have been washed up onto the beach – a testament to the encroachment of the sea – and continue until you reach another group of blockhouses, also on the beach. These remains of the “Atlantic Wall” are a favourite spot for graffiti artists.

Carry on a little further, veering left towards a metal post, near which there is a bin for collecting rubbish washed up by the sea.

(2) Climb up the dune via a sandy path, then continue to the right, despite the Yellow Cross, taking care to stay on the designated paths set out to protect the dune. Please ensure you follow these guidelines for the preservation of the dune environment. Look out for three houses on your left and turn left towards them to find theGR®® and PR®® routes.

GR® 34 (White and Red) +PR®® (Yellow)

(3) Go round the houses on the right, continue along the gravel path which leads
access these houses and reach a fork in the path.

No signposting

Let theGR®® andPR®® turn right and carry on straight ahead until you reach the junction with a road. Turn right and follow this road for about a hundred metres until you reach a signpost. On the right, a sign for a crêperie.

GR® 34 (White and Red) +PR®® (Yellow)

(4) Turn left and follow this wide path lined with spindle hedges. Pass a house (Kerfeunteun on the map), then leave the Vouden Lan estate on your left and arrive at a large tarmac area, which is in fact the training ground for a lorry driving school

(5) Turn left off the road, walk along the edge of a field on your left and continue straight on towards a marshy area. Turn right, walk up a long lane lined with spindle trees and reach a road blocked by a barrier. Continue to the junction with a small road branching off to the right.

(6) Carry on along the road through the pretty hamlet (thatched cottages and beautifully restored buildings). At the end of the hamlet, continue along the road coming from the right until you reach a three-way junction.

(7) Turn left at the three-way junction and carry straight on, past the last houses, along a farm track. You’ll come to a signpost and an inconspicuous sign reading ‘Chapelle Saint-Évy’.

(8) Turn left onto a grassy path that descends towards the Saint-Évy Chapel. Cross the footbridge, which is extended by walkways to help you cross this marshy area, and emerge at the chapel with its adjoining fountain. Head back up the opposite side of the valley (there’s a picnic table at the top).

(9) Turn left and follow the gently sloping path. Please note that this clay track, used by agricultural machinery, may have deep ruts, particularly after rain.

(10) At the signpost marking the fork towards the Étang de Saint-Vio, ignore the path leading down to the lake and continue straight on to reach the buildings of the Maison de Baie d’Audierne, housed in the restored farmhouses of the hamlet of Saint-Vio.

N.B. The watchtower (bird observatory) shown on the IGN map is no longer in use: entry prohibited.

At the road, turn right to reach the Chapel of Saint-Vio. Take a moment to admire this small chapel, standing alone in its enclosure surrounded by low stone walls, and walk past the Pierre de Saint-Vio, a stele with cup marks dating from the Iron Age (750 to 450 BC).

(11) Cross the road and continue along the grassy path leading to the fountain and the wash house.

(12) Cross a small stream via a footbridge to bypass a protected area for birds to rest, and reach a T-junction. Turn right and continue towards the clearly visible crusher and the car park (S/E).

Notes

To make the most of the vast expanse of the beach, visit at low tide. Check the tide times.

On the dunes, an area protected by the Conservatoire du Littoral, please stick to the marked paths and follow the posted instructions.

The wind can be very strong and, in summer, several sections of the route are in full sun.

On the beach, there are a few unmarked naturist areas.

An easy walk with little shade, and a lovely picnic spot by St Evy’s Chapel.
Bear in mind the tide for the section of the walk along the beach – it’s definitely better at low tide – and this stretch of beach is actually about 2.5 km long. You leave the sandy beach at exit 33; if you miss it, it’s no problem – you’ll rejoin the route at the next one.

Hello,
We completed the hike in dry and very cool weather. Despite this, we encountered a few setbacks due to the water level in the marshy areas:
The footbridge at point 8 consists of two sections which, as they were positioned, seemed too far apart for us to reach St Evy Chapel without risking falling into the marsh. The area can easily be bypassed by taking the country road, which allows you to rejoin the route at the chapel, but on the other side.
- On the marshy paths, there are not only significant ruts, as indicated in the description, but also sometimes deep holes.
By avoiding the winter months or taking a change of clothes in the car, this is a very beautiful hike that we will certainly do again, perhaps as early as this spring.
Best regards

A beautiful hike. The car park at the start is easy to find. The crusher and the wall are impressive. The duration and distance of the route are as indicated. We followed the marked route except between points 3 and 4, where we followed the GR34 via Pen ar Vouëz, which saved us 100 metres of road, and between points 10 and 11, where we took the path down to the St Vio pond and walked along the pond to reach the birdwatching tower. The two small chapels we came across are very pretty.
Thanks to the author.

A fairly easy route that takes 2½ hours to walk. Enjoy a breath of fresh sea air at the start, followed by the tranquillity of the countryside. Along the route, there are two beautiful chapels, which are unfortunately closed.

Thank you for this review.

As I did this trip outside of the summer season, I forgot to mention it.
I have just added it to the "practical information" section.
Kind regards

A very pleasant walk under a beautiful blue sky. I extended the route a little at the beach because I wanted to see some "Blockhaus", but overall, nothing to complain about: reliable route, very pleasant paths, beautiful natural scenery. However, it should be noted that along the beach, especially in summer when the weather is good, there is a naturist area... so if you go there with children, don't be surprised to see a few people walking around naked.

We enjoyed this very different walk along the entire length of the route: beach, marshes, a few roads, footpaths. A very pleasant afternoon in the sunshine.

Thank you for your opinion.
I think an information board had been put up.
Perhaps I imagined it, because I often had the same thought as other people to whom I showed these ruins.

Best regards
