Bélon estuary, countryside and coastline starting from Kerfany Beach

Three complementary and very different atmospheres for this hike:
- The Bélon estuary via Beg Porz, Port du Bélon and the coves of Lanriot and Sainte-Thumette,
- The countryside, with its picturesque villages and the tranquillity of the Kerfany stream valley,
- The cliffs, small beaches and viewpoints of the customs officers' path.

Please note: following a landslide, it is no longer possible to connect the points (1) and (2) via the GR®34 cliffside path. See Practical Information for a detour.

Description of the walk

Park in the Kerfany Beach car park.

(S/E) Cross the beach esplanade on a wooden walkway, follow the path uphill towards the Lotissement de Kerfany les Pins road and turn left to Pointe de Kerfany. Beautiful views of the Bélon and karstic cave estuaries, Pointe de Penquernéo and Port Manec'h on the other side of the estuary.

GR® markings (white and red)

(1) Retrace your steps for a few metres, turn left onto the GR®34 immediately after the monument to those shot in 1944 and follow it along the cliff to the Domaine de Beg Porz. Please note: this cliff path can be dangerous and is not recommended for young children or those prone to vertigo. See Practical Information for an alternative route.

(2) Continue on the GR®34 along the Bélon to reach Port du Bélon. Beautiful view opposite Château de Bélon and its oyster farms.

(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 that leads to the Chapelle de Lanriot. Note the Christianised protohistoric stele and outdoor pulpit.

(4) Retrace your steps and continue right on the GR®34. Reach the bottom of the cove, cross a stream on a footbridge, pass a fountain and continue to the sign for the Kermeur Bihan covered passage. Take the time to go 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 passage.

(5) Retrace your steps and continue right on the GR®34. On the other side of the Bélon, you will see 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 Kersaux slipway.
Off the marked trail

(6) Follow this path uphill and cross a trail 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.

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

Follow it until you reach a trail on the left after No. 5.

Mountain bike trail markers 57, 58 and 59 (orange)

(12) Pass the chapel, turn left onto a barely visible path and reach Allée des Chaumières. Turn left and follow this small road to the end, which continues as a path. Note the beautiful collection of old houses and thatched cottages along the way. Continue on this path, ignoring a path on the right, then on the left, and reach Rue des Embruns (D116).

(13) Cross it carefully, turn left for a few metres and then turn right onto a small street called Hent ar Len towards the village of Kerdoualen. Continue along this road, which gradually turns to the right, and continue right onto a sunken path (marked VTT 57, 58 and 59). Follow it until you cross Hent ar Len again.

Notes

Between (1) and (2), the GR®34 cliffside path is closed due to a landslide. To avoid it, after point (1), continue along the Kerfany housing estate road and turn left to reach the Domaine de Beg Porz, then theGR®34 at point (2).

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

The Visorando app or GPS are recommended to follow the route in the countryside, where many paths intersect.

The GR®34 coastal path can be busy in the summer months. It is much quieter once you leave the coast and head into the countryside.

You can shorten the route by about 3 km by turning left at the point (5) after the covered walkway to reach the village of Kermeur Bihan at the 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 Domaine de Beg Porz (2) and Port du Bélon (3) (preferable in summer).

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

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.

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

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.
