Holiday Sketches Part 3 – Estuaries, harbours and towns



Three beaches along the Baie d’Audierne  


The first of these (le Gored west of Plozévet) was straight after our journey to Finisterre on 9th May. This was a good introduction to the hard, mainly crystalline rock geology here. My knowledge of French geology is not as good as that of the UK, but much of the geology of Brittany and the Amorican Massif underlying western France has been shaped by three continental collisions. The first one during the Neoproterozoic era c 600Ma, the second and third ones were the Caledonian and Hercynian (Variscan) orogenies during the Palaeozoic, as the components of Pangaea supercontinent came together. This has all resulted in extensive igneous intrusion (granites) and deformation – alteration of sediments under heat and pressure (metamorphism) such as schists and sheering. The layers (sedimentary bedding planes and foliation) in the low cliffs and wave cut platforms on this beach and the one we visited the following day (Porzambréval, almost nextdoor, 10th May) showed a consistent, distinctive roughly east – west alignment. Any sedimentary beds were steeply dipping, almost vertical in places.




At low tide rock pools in the platform. Among the birdlife, a comorant and little egret.
Eastwards along the coast, a marshy area, drained by streams. Got across the first one As there was a bridge and it was relatively narrow. Yellow irises along its banks. Second one, though, much wider and deeper, tumbling as it ran down the sloping backshore. No bridge near the beach, so couldn't go any further. Took these streams to be formed from springs. Though the bedrock is crystalline and impermeable, I believe there are fractures which hold water, forming an aquifer. There were wells marked on the map. As no bridge over the second one, took this to mean it was well topped up and flowing more copiously than usual.

After a slower paced morning at the cottage at the end of the first week (15th May) we went to Penhors which was about midway along the Baie d’Audierne. Car park busy, though at least to begin with, very few people on the beach. This was because the tide was in and the beach was being pounded by waves of considerable force. A few brave surfers. To the south, the more distant end of the beach a mass of white foam and sea spray. Near the car park, the waves crashed over a low seawall, two of them with a gap. Take it these walls were to dissipate at least some of the wave energy in that particular bit of beach-the waves having eaten into the cliff forming a small bay. At either end were banks of granite rock armour. The cliffs here were low, generally no higher than about 3m. The upper metre or so was unconsolidated loess, making them particularly vulnerable to erosion. In places, the GR34 path was getting close to the edge, some of the houses not that far off either. More rock armour. To the north, the cliffs gave way to shingle and a small lagoon like those we'd seen further along the Baie d 'Audierne last weekend. Once again, no way across the outlet. Part of the backshore fenced off far birds laying eggs on the shore. At the edge of the lagoon, a group of large gulls and a cormorant with its wings opened out. Sketched the waves, sat on the shingle.

Pointe du Raz and Pointe du Van

Pointe du Raz from Pointe du Van
These are the most westerly points on the mainland of southern Finisterre with the Baie de Trépassés between them. We visited Pointe du Raz, the more southerly one, during the middle of the first week, beginning by walking round to the point from Bestree. Here, there was a small harbour, reached by a very steep slipway and a lift down from the end of the lane above the cliff with a crane. Built originally service the lighthouses just off the Point. It was formed by a line of rocks, with two sections of concrete wall filling the gaps. Though very sturdy looking, this wall has been breached by the waves several times during storms. On this particularly exposed stretch of coast, the south side of the Point is about as sheltered as it gets.  



From there, there was a short but tricky, narrow stretch of path with sheer drops to our left. It opened out near the Pointe, but we really had to concentrate and watch our footing. It was a bright day, with superb visibility. The Point itself was a gradually tapering area of granite, with rock outcrops just offshore. Behind us was the Semaphore tower for safe navigation, in front of this a Mary figure - Notre-Dame-des-Naufrages, Our Lady of the Shipwrecked. Two lighthouses, La Vieille the nearest, with slanting blocky stone design. Beyond these was the low lying Île de Sein, with its own long narrow lighthouse on the north side.  Far out to sea beyond the island was the especially exposed Phare Ar Men.




The Raz at Pointe du Raz was the Raz de Sein, between the Pointe and the Île. The waves and currents here are especially treacherous, with tidal currents of the order of 7 knots according to the display in the visitor centre.  We were here on a calm day with very 5kph winds and a neap tide. Even so the waters here were very turbulent, with white breakers, especially around the rock outcrops with the lighthouses. Seagulls in their wake. Several boats braving them. Some impressive Youtube footage of stormy seas here, with waves exceeding 10m and overtopping the lighthouses.

It was very busy on the Pointe, this being one of the key attractions in this area, though the crowds thinned notably at lunchtime.



To the north of the Point was the Baie de Trépassés. On the far side of it, the Pointe du Van. In the distance beyond it, the next Finisterre peninsula northwards. We may have seen the western end of the Brest peninsula which sticks out westwards beyond it.

The north side was relatively sheltered, with a the sandy beach. We walked to far southern end of this along the coast path, enjoying the vivid greens of the sea nearer the shore, the energy and white water wave patterns as waves broke on the shore / over the rock outcrops. Some interesting wave patterns as the water shallowed towards the sandy beach.


We looked round the Pointe du Raz visitor centre after we had walked back up the cliff. It was striking to compare and contrast the management of Pointe du Raz to England’s Lands End. The latter wasn’t too bad when I visited as a child in the late 1970s, when there was just the signpost. By the early 1990s, however, it had been ruined by commercial development in the form of a theme park and shopping area.  Since 2004, Pointe du Raz has been one of France's National Sites which are given special protection. This was one of a number of steps taken during the past few decades to protect the area from environmental damage, including tourist erosion, and intrusive commercial development. The car park is now 800m from the Point (shuttle bus if wanted). This was the only place throughout our holiday when we had to pay for parking (six euros) but we didn’t mind as it went towards the upkeep of the site. Given all these improvements, I was astonished to learn at the visitor centre that they very nearly went and built a nuclear power station just along the road at Plogoff. The locals were up in arms –literally. A photo from 1980 of people clad in metal armour brandishing shields. Thankfully, the powers that were back then listened and nothing came of it.

We visited Pointe du Van towards the end of our second week. As the day went on, it became more hazy / misty, but when we arrived, it was bright and clear, with views back to Pointe du Raz and westwards beyond the Ile-de-Sein where the houses and lighthouses caught the light. To the north was  the Presqu'Île de Crozon and western tip of the Brest peninsula beyond it. Above the cliff was a chapel and a stone structure housing a fountain, presumably a spring, though any upwelling pretty paltry and subsumed by green algal gunk. We did a short walk rounding the Pointe du Van to the next headland on the north coast, the du Castelmeur. Another stretch of coastline with sheer cliffs and the path was narrow in places, though it wasn’t as busy as at Pointe du Raz. The rocks here seemed to be more mixed, with resistant granite nearer the Pointe du Van and steeply dipping, less resistant bedded rock on the . In places, there had been slippages, Some slate-like rock on one cliff lower down.

Point de Penmarc’h

This was the headland at the southern end of the Baie d’Audierne. Pointe du Raz was visible at the far western end. This Pointe was very different to those on the north and western coasts: it was built up, with an interest mix of lighthouses, beacons and working harbours with fishing boat making for an interesting mix of sketching material.  We made two visits here, parking next to the Phare Eckmühl, the taller of the two lighthouses and furthest inland at the Pointe, built in 1897. In front of it was le Vieux Phare (the old lighthouse) which now housed a small museum and art gallery. Nearest the rocky shore was a semaphore / coastguard station and a C15th church immediately behind it. Some colourful snail shells on the shore here. Next to the car park, a small park with an installation comprising various funnels to speak into and listen to what came out. They were about the trans-Atlantic cable terminus here.



On our first visit (13th May) we walked north from the lighthouses to the working harbour at St. Guénolé and the more massively rocky granite shore beyond it, following the GR34. I liked this bit of coast for all the lighthouses and beacons, though I preferred everything during the morning, before the cloud cleared. The colours were stronger. When the sun came out later the light was a bit harsh. By then, too, the tide was further out, exposing lots of smelly seaweed on the wave cut platform either side of the lighthouses. Though there was more of a mix of seaweed species than the green scum afflicting the Hamble etc., the smell stayed with me like an after-taste all the time we were looking round the museum and even, for a while, back at the cottage. In Brittany, they harvest seaweed for use as fertiliser, though the blooming algae can go too far, just as it does back home. I gather it’s worst along the north coast, which says something about the water quality of the English Channel.


In the harbour at St. Guénolé were various size boats from smaller cruisers to the heavy duty fishing boats near the warehouses. One of these, appropriately for a granite coast, was called Pluton.  A lifeboat and lifeboat station. To our eyes, the random colourful blobs of paint decorating the walls near the path round the edge of the port were reminiscent of some forms of abstract art. A selection of signs and notices noticed, mainly relating to the port and the sea.

Round from the port was the Plage de Pors Carn. Here, shore was very rocky with massive boulders of granite. The shapes these formed were interesting, but it was all steeply shelving and prone to big powerful waves and swells. All the warning notices about dangerous waves (vagues) and risk of drowning (noyade), even when the sea is calm suggested this stretch of coast was dangerously deceptive. I hope the authors of the youtube footage here during the storms the winter before last were being careful.

Just beyond here, the backshore opened out, with some older, potentially very exposed buildings. A view across the Plage to Pointe de la Torche. Beyond this, the Plage de Tronoan, the long sandy beach running along the southern end of the Baie d'Audierne, its bright sand showing up strongly as the sky began to brighten. Apparently bathing is dangerous here, too. When we saw the waves at Penhors two days later, we got a fairly good idea why.

After walking back to the Pointe, we had a look round the museum and art exhibition in the Vieux Phare, though we decided against the Phare Eckmühl as didn't fancy the vertigo-inducing steep, long, narrow spiral staircase. In the museum, a display about lighthouses: the evolution of lamps from basic wood fires to Incandescent bulbs set in arrays of parabolic lenses to focus amplify the beam. A selection of gas / oil lamps, big incandescent bulbs, associated tools. Photos showed the development around the Pointe, including construction of this lighthouse; the evolution of the harbour at St. Guénolé, the various beacons. As usually happens, everywhere became progressively more built up.  Saw from one of the later photos at Penmarc'h (1980 and after) some beach on the SE side of the lighthouses reclaimed and built on, having previously been a seaweed harvesting site.

On the first floor of the Vieux Phare, an unusual at exhibition space, now housing an exhibition of paintings by Henry Kérisit depicting sailing boats. A mix of drawings, paintings in gouache, ink and wash, along with collages on canvas / linen. I liked the simple boat and sail forms in the collages. The boat portraits much more precise and more illustrative.  The portraits of Portuguese barges were interesting for the different design of the vessels compared to more familiar northern European barges: a more curved form. Their colourful decoration was reminiscent of UK canal boats. Views through the windows out to the shore were pictures in themselves.

Our second visit (18th May) was for a few hours during the middle of the day, after postponing Menez-Hom (see Estuaries, harbours and towns) because of the rain, drizzle and mist. It was murky out to sea, the showers were coming and going. During an early lunch, I tried sketching the Vieux Phare from the car, though windows quickly steamed up. I then went outside, where I could see over the wall and had a go at sketching the view to the north, towards St. Guénolé with the two black and white striped beacons in the middle distance. The tide was now well out, revealing a broad wave-cut platform comprising low, rounded granite rocks / boulders interspersed with lots of seaweed and a few pools. It was very blowy and I forgot to bring a buff or scarf, so my hair blew everywhere. As usual, l worked with Inktense water soluble pencils and dual tip brush pens. The lighthouse offshore from St. Guénolé disappeared into the murk. When it got a bit damper, I cowered behind the wall and carried on, meaning l didn't see the short but sharp shower coming. I dashed into the car just in time, before everything onto page ran into a sodden, soggy mess. Actually, I hit the sweet spot – just enough soaking to loosen everything up by allowing the colours to blend wet-into-wet. I dabbed a few bits, then left my sketchbook to dry on the backseat of the car while I went and joined my other half at the harbour at Kerity to the south of the lighthouses as the rain eased off. No more showers after that one.



There, we walked out onto both the piers at the harbour, beginning with the longer, more easterly one. Views east towards le Guilvinec and the fishing port there. Les Etocs rocks offshore to the south. On the seafront near the piers, a restaurant named after them. The tide was now beginning to come in, quickly covering, the wave-cut platform. There were subtle but noticeable currents in the shallow water near the piers, interplaying with the water movement in the wind. Presumably, the currents arose from water flowing between the rocks as the tide rounds the Pointe de Penmarc'h.


Back at the car, sketchbook now dry, I drew the Phare Eckmühl. On our way back round the lighthouses, we spotted a barometer on east side of the Vieux Phare. The pressures on the gauge ranged from 920 millibars up to 1070 millibars. Both these extremes were beyond the all-time highs and lows recorded in north western Europe. The accompanying weather ranged from Tempête (storm) near the lower end, then Pluie ou vent (rain or wind), to beau temps (fine weather) and Très Sec (very dry)at the highest pressures.







Cap Sizun north coast – Pointe du Millier



Visited during the middle weekend (16th May). We parked bear Pointe de Millier and walked from there to the next headland westwards, the Pointe de Trenaouret. A grey, at first drizzly start, but the sky cleared around late morning. The rest of the day and evening were sunny. First, we had a quick look at Pointe du Millier near the lighthouse. Certainly from behind, it looked more like a house than a lighthouse, semi-circular tower with the light being built into the seaward facing wall of the house.  

We then had a look at the watermill, the moulin a eau in the small steep valley to the SE of the Pointe. The wooded valley here was very lush and moist. Below the mill, a stream divided into rivulets and flowed down the slope. Above it, it was channelled into a narrow conduit running directly to the water wheel on the west side. It was a large wheel, wider than the two storeys of the stone building / slate roof. It was turning as the stream was flowing well. A spring-fed stream? A few small seasonal streams marked on the maps in the Cap Sizun area, usually uppermost reaches.

From the mill, we rejoined the coast path and walked westwards. Stopped to sketch at the small sandy beach called the Plage de Pors Peron. Just round the cliff to the west was a small, inaccessible cove. Path then climbed steeply up again, then down again to a small inlet with a slipway. Memorial plaque on right, August 1943.

Lunch on the Pointe de Trenaouret, looking back towards Pointe du Millier, as it was a bit chilly, blowy on the west side of the Pointe. Some vocal small birds about. Nests among the bracken, gorse etc., perhaps. A mix of rounded granites, especially at the headlands and more blocky / bedded rock apparently dipping upwards of 45 degrees.




Les Tempetes d’Hiver 2013 - 2014

Like much of the UK Brittany took a hammering during the seriously, serially stormy winter December 2013 – February 2014. At the time I was too wrapped up in what was going on this side of the Channel to follow it, by all accounts the effects of gale force winds, heavy seas, high tides, coastal and fluvial flooding were all just as bad. Firstly, there was the Tempête Noël, aka Cyclone Dirk, the exceptionally deep low pressure system which brought the damaging, disruptive gales just before Christmas 2013. There was bad flooding in Morlaix on the NW coast. In Quimper on Christmas Day, the Odet was rising and at Châteaulin the Aulne transformed into a raging torrent. Come the new year, warning maps from Météo France pointing to the same high tides which prompted the severe flood warnings on the Severn (beginning of January and February). The exposed western and northern coasts, notably Pointe du Raz and St. Malo were pounded by waves, some exceeding 10m. There was flooding along la Vilaine, the longest river in Brittany, around Redon, along with further, repeated episodes of débordement in Châteaulin and Quimper –Le Steïr sort de son lit (out of bed) in one youtube video, the town bracing itself as the Odet rose during the first week of February. 

Like the same storms in the UK, it all generated plenty of youtube footage. These are links to a selection of it:
