Bélon estuary, countryside and coastline starting from Kerfany Beach

Three complementary yet very different settings for this walk:
- The Bélon estuary via Beg Porz, Port du Bélon and the coves of Lanriot and Sainte-Thumette,
- The countryside, its picturesque villages and the tranquillity of the Kerfany Stream valley,
- The cliffs, small beaches and viewpoints along the Customs Officers’ Path.

Description of the walk

Start at the car park at Kerfany les Pins beach.

GR® markings (white and red)

(S/E) Cross the beach esplanade via a boardwalk, follow the path uphill towards the road to the Kerfany les Pins housing estate and turn left towards Pointe de Kerfany. Beautiful views over the Bélon and Aven estuaries, Pointe de Penquernéo and Port Manec’h on the other side of the estuary. Retrace your steps, passing the memorial to those shot in 1944 on your left.

Off the marked trail

(1) Continue along the road then turn right onto a wide lane closed to vehicles. Turn left at the end of the lane to reach a triangular junction with a central reservation. Ignore a street on the right, go round the reservation on the right into Rue Bel Air and turn left towards the Beg Porzh estate. Turn right downhill towards a car park, at the far end of which a flight of steps joins the GR®34.

GR® markings (white and red)

(2) Continue right along the GR®34, which runs alongside the Bélon, to reach Port du Bélon. There is a beautiful view opposite of Château de Bélon and its oyster beds.

(3) Follow Rue du Port du Bélon and, after No. 88, turn left onto a discreet path that descends towards Anse de Lanriot. Continue right on the GR®34, pass a small cove dotted with fishing boat wrecks and turn right onto a path leading to the Chapel of Lanriot. Note a Christianised protohistoric stele and an outdoor pulpit.

(4) Retrace your steps and continue to the right on the GR®34. Reach the end of the cove, cross a stream via a footbridge, pass a fountain and continue to the signpost for the Kermeur Bihan covered walkway. Take the time to head down to the left towards the slipway and admire the view of Port du Bélon and Château de Bélon. Turn right then left to reach the Kermeur Bihan covered walkway.

(5) Retrace your steps and continue right onto the GR®34. Note, on the opposite bank of the Bélon, Anse de Penmor, the village of Méjou Lannéguy and the Chapelle Saint-Léger. Follow the GR®34 until you reach a path on the right at Anse de Sainte-Thumette, just before the slipway at Kersaux.

Unmarked

(6) Follow this path uphill and cross a track on the left. Follow it for a few metres to reach the Fontaine de Sainte-Thumette. Retrace your steps and turn left until you reach a T-junction.

Mountain bike markings 57, 58 and 59 (orange)

(7) Turn right and follow a path that winds along the edge of the Bois de Kermeur. Ignore the paths branching off to the right and left and continue to a small road in the village of Kermeur Bihan.

(8) Turn left onto this road and continue to Kermeur Braz. Turn right, cross the village, continue down a path and reach a stream.

No signposting

(9) Cross the stream via a footbridge and turn immediately left. Climb this path and turn right at the next junction. Continue along this path, which leads onto a small road called Chemin de Park Roz, and cross Rue du Bélon. Follow it to the right for a few metres and turn left into Rue de la Plaine. Follow it to a trailhead on the left after No. 5.

Mountain bike markings 57, 58 and 59 (orange)

(10) Follow this downhill path, which gradually turns right as it runs alongside the Kerfany Stream valley. Continue along this path, ignoring all the paths to the left and right, until you reach the village of Clec’h Burtul. Turn left to reach the Kerfany Stream.

(11) Ford the stream, follow the path on the right and turn right to reach the Saint-Guinal Chapel (shown as Saint-Guinal on the IGN map, but Saint-Guénaël on the signposts).

PR®4 (Yellow) signposting

(12) Walk past the chapel, turn left onto a barely visible path and reach the Allée des Chaumières. Turn left and follow this small road to the end, where it continues as a path. Note the beautiful cluster of old houses and thatched cottages as you pass. Continue along this path, ignoring a track to the right, then to the left, until you reach Rue des Embruns (D116).

(13) Cross it carefully, turn left for a few metres and then right into a small street called Hent ar Len towards the village of Kerdoualen. Continue along this road, which gradually curves to the right, and keep right into a sunken lane (MTB markings 57, 58 and 59). Follow it until you cross Hent ar Len again.
(14) Turn left, pass a wash house and turn right onto a narrow path just before the Porzh Gwenn cul-de-sac. Follow it to join the GR®34 at Prat Hervet Beach.

GR® markings (white and red)

(15) Follow theGR®34to the right, passing Grise Beach and Pointe de Kerhermen to reach the car park at the start (S/E).

Notes

Due to the risk of landslides, it is currently not possible to use the GR®34 between points (1) and (2), although its route is still visible on the IGN map.

This route crosses several streams, the banks of which can be very muddy in winter or after heavy rain. Waterproof walking boots are strongly recommended.

The Visorando app or a GPS device is recommended to follow the route in the countryside, where numerous paths criss-cross.

The GR®34 along the coast can be busy in the summer months. It is much quieter once you head inland into the countryside.

You can shorten the route by about 3 km by turning left at point (5) after the covered walkway to reach the village of Kermeur Bihan at point (8).

For an even shorter route (just under 10 km), after the Notre-Dame Chapel at point (4), turn right at the end of Lanriot Cove onto a path that joins Rue du Bélon. Follow it to the left, then turn right onto a path that leads to Rue de la Plaine. Turn left to reach point (10).

Alternative starting points at Pointe de Kerfany (1), near the Domaine de Beg Porz (2) and at Port du Bélon (3) (recommended in summer).

Picnic tables at the starting point, at Pointe de Kerfany and at Lanriot Chapel.

Toilets at the starting point.

Worth a visit

Cliffs and beaches around Kerfany.

Beautiful views of the Bélon and karstic cave estuaries, the Penquernéo and Kerhermen headlands and, on a clear day, Île Percée, Île de Raguénez, Île Verte and Île de Groix.

Gorgen, Lanriot and Sainte-Thumette coves.

Kermeur Bihan covered walkway, one of the best preserved in southern Finistère.

Notre-Dame Chapel (19th century), outdoor pulpit and protohistoric stele of Lanriot.
Chapel of Saint-Guinal or Saint-Guénaël (18th century).

Fontaine de Sainte-Thumette (late 17th century).

Small port of Port du Bélon.

Rich architectural heritage (thatched cottages, bread ovens, wells, fountains and wash houses) in the inland villages.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

Thank you for this review.
I have reviewed the route and description of this hike following the closure of the GR34 between points 1 and 2. Please let me know if the signposting on other sections of this route needs clarifying.

A really nice route, with plenty of shade on hot days, but the signposting needs improving!

A lovely route. The first part is shaded by the woods, which is very welcome in hot weather!

Thank you very much for your feedback. I was not aware of this collapse.
I will amend the route and the description of the hike accordingly so that the cliffside path after point 1 is no longer mentioned.

an excellent route, as rich as it is varied! Definitely worth doing again and again, as the diversity of the landscapes you pass through deserves to be appreciated even more.
i would like to point out that the coastal path has collapsed just after the marker at point 1 on your description. The passage is blocked and you have to take the road to get back on the planned route. (I couldn't report it via the app because I'm following the track on my GPS... the app isn't reliable enough on my iPhone)

Thank you for your feedback and for adding photos.
As indicated in the Practical Information section, a GPS or the Visorando app are recommended for this route, where in some places the signage is conspicuous by its absence or is very discreet.

We did this hike in beautiful weather at the beginning of April, when the trees were still in bud, which made it easier to see in the wooded areas. The GR 34 section is magnificent. The return trip is pleasant through the wooded countryside. The app is very useful for finding your way, as the markings are not always very clear. It should be noted that the trees are magnificent, but some have suffered from storms in recent months. Nevertheless, the path is clear. We shortened the hike from point 12, St Guinal Chapel, to the finish for timing reasons. Overall, a very beautiful hike, fairly easy. Thank you. Bernard and Armelle.

A beautiful hike along the banks of the Bélon, where we saw many birds, then back inland through the woods, passing through a few hamlets. Almost no tarmac

The first part of the walk along the Belon was very pretty. We enjoyed tasting oysters in Belon. However, the rest of the walk was along the road, which was not enjoyable and even dangerous, especially with dogs. We should have turned back and stayed on the footpath.

Hike to do...
Three distinct sections with a variety of very pleasant landscapes. The banks of the Belon, the forest, the beach... Fairly uncrowded. Some sections are a little difficult or even dangerous (unprotected cliffs), particularly in the first section on the banks of the Belon and at the end.
Avoid in bad weather as the route quickly becomes muddy and a little dangerous (slippery?) in the estuary.
It's best to set off in the morning, otherwise the beach car park will be full. And the added bonus of setting off early is that you can go for a swim at Kerfany beach at the end! It's worth noting that there are few roads and built-up areas, which is great!
I recommend it

A very beautiful walk from start to finish. Varied, following the Belon river at the start, then through lovely woods and sunken paths, returning via the coastal path. Very pleasant.
