||Bill leaves home at midday and drives 200 km to Bergamo. Flight on time and arrives at
Santander early 19:20. Collects car, phones hotel to advise after-midnight
arrival and seeks advice on where to eat nearby at tourist kiosk
in the airport. Mike passes the arrivals exit at 22:05 and we proceed
(as recommended) to Lincres where we end up at a rather unpretentious
Bar Carlos. But the food was remarkably good – and we were hungry.
Lomo for Mike, and jamón for Bill plus good chips all washed
down with Ribera del Duero.
Arrive at Llanes around 00:45 and after a quick walk round the town
we checked into the Montemar Hotel.
||Walked into town in search of breakfast and settled on the Xana bar by the estuary for
café con leche and an enormous slice of tortilla. The weather
was overcast and the Sierra de Cuera was hidden behind the clouds.
So a drive south was planned, but near Puente Nuevo the sky had cleared
and we decided to drive up to El Mazuco. Parked at the paddock
beyond the village and contoured round towards Ojo del Río. Very
low water levels and the cave entrance was more exposed, but the
entrance pool prevented inspection of the passage.
We proceeded up a steeper path climbing over walls and barbed wire
reaching the Vega del Cubo which is a large closed valley with some
sub-depressions. On the south side is a cliff face and cave entrance
(Collau Rubiera, GPS’d in 2004). It appeared to go
but we were not prepared for a flat-out crawl. Besides, the prospect
of lunch at El Roxin tempted us back to El Mazuco. For a first day’s
walk we were fairly satisfied.
Bill at Collau Rubiera
We ordered chorizo, criollo and patatas oli ali (just
3 plates) but we couldn’t finish the excellent food. After a drink
in “El Sucon” we returned to Llanes via Posada. For dinner we shared
a plate of cheeses at ‘La Amistad’ but we couldn’t finish that either!
||Grey drizzle in Llanes, so our automated response – head South – kicked
in. With the new motorway to Unquera open we were in La Hermida
in 45 minutes! As predicted we had left the clouds behind and we
were soon enjoying some picón (queso de Bejes)
in the sun outside Posada La Cuadrona.
Our objective for the morning was to walk up the Riega Cicera valley
from the Gorge to the village of Cicera. After some to-ing and fro-ing
to find a parking space (at altitude 170m), we started up the track
which was surprisingly steep in places. Fortunately the day wasn’t
particularly hot, and the path was often shaded by fig trees, etc.,
but even so we were very pleased to find a bar when we got to the
village, at altitude 500m!
Descent was much faster, for a total walk time of 2:45 (track), and we arrived back in La Hermida a little after 3pm –
in time for lunch (sopa and escalope). Back to Llanes via
Urdón and along the Cares Gorge, stopping at La Molinuca at the
road leading to Cueva Llónin, etc. Shared a dish of Fritos de
Pixin at Rte. Salero, for dinner.
||After the previous day’s walk we were feeling that more caving and less walking might be in order,
and as yet again the skies were overcast we planned on Cueva del Trumbio. The big cave is notionally only 10 minutes from
the road south of Covadonga to the lakes. However a previous attempt
in 2012 had failed as the entrance depression had been completely
overgrown by gorse.
Perhaps in previous decades, the gorse was kept under control by
cows but EU policy has been to reduce the butter mountain by reducing
the dairy industry. This has had the side effect of making cave
entrances less accessible! To add to the obstacles the access field
was very wet and muddy and protected by barbed wire. Bill managed
to lacerate a finger as a branch he was holding on to turned out
to be rotten. (Nothing too serious, a clean wound.)
Within sight of the entrance, we attempted a direct descent but soon
found ourselves surrounded by gorse and above a vertical cliff face.
Frustrated, we retrace our steps to the track and walked away from
the cave towards a llosa (meadow). At this point we were at stream
level (no water). The mossy rocks looked pretty treacherous so instead
of following the steep streamway we contoured along on the far (southern)
bank in the woods. No gorse here but plenty of holly trees! And
mud on the steep path. Bill managed to fall over and the second
time got rather dirty! However this new route worked and we got
to the entrance.
Cueva del Trumbio entrance
Honour satisfied and after a few photos we retraced our steps. The
llosa did not reveal anything of speleological interest but is full
of little sinks. As we walked up through the gorse there was some
slight drizzle; welcome, as we were warm from our exertions.
Lunch in Casa Morán, Benia, recommended for its excellent fabada,
followed by lamb. Good quality food for a menú del día but
pricey at €38 for 2 including Ribera del Duero. Back to Llanes
via Posada and autovía.
Dinner at El Almacén, bocarte (fresh anchovies) for Mike and
boletus mushrooms in Picón cheese sauce for Bill.
||Glorious weather, sun with some cloud, 20°C. As it was Saturday
we decided to avoid busy places such as the Lakes or Bulnes, and
headed to Tielve to reconnoitre possible tracks towards Valfrío,
to start us up towards the Majada de Tordín. A steep concrete
track led invitingly NE from the village, but it was exceptionally
steep and very soon the rental car declined to proceed further.
A complicated team effort succeeded in executing a multi-point turn
and a safe descent.
We decided the weather was ideal for a walk above Sotres, and headed
East. At the hairpin bend junction below Sotres, however, was a
large coach, blocked by cars parked on the bend. Unable to go up,
we turned off and went a short way along the track towards Áliva
to turn, seeing a number of tired runners and spectators. After
many dusty hill starts, etc., we made it back to the hairpin bend
and were able to depart down the hill. Meanwhile a stream of vehicles
– and a second coach – were joining the long queue that was trying
to get up the hill.
Very relieved to have open road, we returned to Arenas where we discovered
we had stumbled onto the final stages of the Travesera de Picos De
Europa, a 74km(!) run that started in Covadonga at midnight and whose
first runner arrived in Arenas as we were there, 13 hours later.
It now being lunchtime, we carried on to Mestas de Con for a welcome
menú del día. Thus fortified, and a bit frustrated after
the morning’s difficulties, we backtracked to Berodia to explore
the limestone behind the cave at La Foz that we had often noticed
from the Arenas–Ortiguero road. An enjoyable walk covered the area
to our satisfaction, although no significant speleology was found.
The Arenas–Ortiguero road
Back via Rales, but did not meet any of our old friends.
||A bright day but rain forecast. After breakfast at Bitacora, drove east towards Buelna on the old autovía
and stopped briefly near Pendueles after noticing some entrances
north of the road Δ. They may be real
caves but are clearly used by the local farmer and his animals so
were not accessible.
On to Buelna to look at another inland beach (connected to the sea
only by a sea cave). We arrived by car and on foot from the north;
realized this was not the best approach and reversed our path back
to the N634, parked there, and followed the tourist signs to Cobigeru.
A very pleasant walk through meadow and wood, and to our delight
we found a stream emerging from an enterable cave Δ. The same stream sinks in a much larger entrance further
on Δ and we walked in. The stream
meanders off to the right and a larger high level but muddy passage
continues on the left. We did not look for the resurgence to this
system but so near the sea it is likely to be close by and defended
Cobigeru ‘muddy cave’
Another 4 minutes walk brought us to the Cobigeru inland beach, almost
exactly at high tide. To the east, some 4m above sea level, there
was another entrance Δ which Bill entered
using a torch. Initially it was necessary to stoop but after 20m
bigger walking passage was reached with real cave complete with stal.
Bill called back gleefully “It goes” and continued out of sight of
daylight. The sea could be heard and soon seen via multiple entrances
at water level connected to a large chamber. Bill returned to call
Mike and both briefly explored. A satisfactory little through trip
– about 70m long.
Cobigeru inland beach, Buelna
Next stop was the sink cave at Cobijón village which we found in
2014. This is a fine vadose entrance Δ
10m high and 3m wide taking water (and no doubt refuse from the village).
Neither of us were prepared to paddle down the passage (there was
no dry land) so this cave will have to wait. Later googling failed
to reveal clear details of exploration but the cave is well known
to the locals.
We had an excellent menú del día at “Restaurante Las Filipinas”
in Comillas followed by a detour to Camijanes on the way back to
||Despite a poor forecast and ominous clouds, the sun came out and we
headed to the village of Póo de Arenas (1.7km WNW of Arenas).
After crossing the river, tracks to the west zigzag up the side of
Peña del Alba, which has inviting cave entrances in its cliff faces.
In 1975, Bill and Steve Newton found a cave possibly near there.
No such luck in 2016, although a very pleasant walk was had, with
wildflowers, butterflies, and lizards in abundance.
On to Mestas de Con for refreshment, then to Cangas for lunch –
which we expected to be quiet on a Monday. Cangas, however, was
chock-a-block with people and the main streets were closed for the
procession of the Fiesta de San Antonio de Padua. Unable to continue
and in a one-way street, we parked in a police-car rank and took
some pictures. Once allowed to proceed, we decided that the restaurants
in Cangas would be impossible, and headed to Ribadesella. What a
contrast! A cold wind blew, the streets were deserted, and only
3 or 4 restaurants were open. Fortunately one (El Ancla) offered
a menú del día that went down well (salad / fabada, escalopine
al cabrales). Back to Llanes on the ‘old road’, getting another
picture of the promising possible cave above the the Poligono Industrial.
MFC tucking in to fabada in Ribadesella
||Another sunny start, so off to explore a depression recently noticed on the map: Vega de Hibeo (track). Two km south of Meré, a narrow metalled track crosses Puente Cima Cosagre and hairpins up to Ilcedo. From there a pleasant and steadily ascending walk along a limestone boundary took us up a little over 200m in 2km and 1:20, reaching a grassy col overlooking the quite idyllic Vega, with grazing cattle and horses.
We followed the snaking stream to a promising limestone cliff Δ, with several holes and possible caves, but
none of them ‘went’. Back to the col, then down an easier ‘cow motorway’
we’d spotted earlier for the return downhill, which took 52 minutes.
Vega de Hibeo
To El Sucón for menú del día, €9 each, of which the
highlight was salmón a la plancha. Rain started while we were
eating, and more arrived later in the afternoon, but it was beautiful
walking weather in the morning.
||First part of plan was a photo trip in Cobigeru cave at Buelna.
Drove there using the (deserted) old autovía and arrived just as
a coach disgorged dozens of schoolchildren, many of them wearing
helmets. We ‘pushed’ the muddy cave a little further, then carried
on to the main cave. As we feared, a mound of day-sacks (guarded
by a teacher) indicated that a large party had entered the cave.
We walked around the cliffs for a while, then a short foray into
the cave showed that it was thoroughly misted-up and photography
would be pointless.
On (via Unquera and Merodio) to Cueva Toyu to solve some
questions about the survey (is the barn in the right place? etc.)
by GPSing the top entrances. A helpful farmer pointed out our old
nettle-filled favourite candidate and allowed us through his field
to GPS it Δ; we also re-GPSed
Δ the infamous barn NE corner (extended
in 2015). Unfortunately the electricity poles detailed in Peter
Robertson’s 1982 sketch map are long gone,
so we had to defer searching for the “Cueva Roza[da]” entrance.
Toyu ‘nettle entrance’ feature
Asking the farmer about Cueva Rozada elicited an unexpected response:
he directed us to a new (to us) cave entrance a few hundred metres
north – GPSed it Δ for future investigation.
Salmon at Casa Gloria
Key data secured, on to Camijanes for another above-average menú
at Casa Gloria.
Back in Llanes, analysis of the GPS readings and track conclusively
showed that the ‘nettle entrance’ is not one of the top entrances
to Toyu; instead it is the small feature, shown 120m SW of the barn
on the plan and elevation of our 1982 Speleogroup survey, that we had overlooked. We also calculated predicted GPS
positions for the ‘Cueva Roza’ entrance Δ
and the resurgence Δ.
It had rained most of the night but a brief respite at 9am allowed
us to cross the road to have our breakfast café con leche.
On the way to the lakes we stopped for a second breakfast of Gamoneo
cheese in Mestas de Con and it continued raining all the way up to
Bar “Maria Rosa” (1100m) which was doing a brisk business of sheltering
tourists from the damp. We were recognized immediately by the waitress
and granddaughter of the bartender in 1975 whose photograph is on
the bar wall. Although it was only midday, we ordered 2 plates of
food and a glass of tinto. For nostalgia, Bill ordered a half ration
of queso semi-curado – similar to the white crumbly cheese we
used to eat 40 years before, when exploring
Bar “Maria Rosa”, Lago Ercina
Our object had been to walk to to Vega de Comeya – a large flat
depression – but the rain ensured we never ventured further than
30m from the car! It continued to rain until we got to Posada where
we took the autovía back to Llanes. The rest of the afternoon
was sunny (on the coast).
Lago Ercina in damp weather
||Rain, so south again. New route (motorway + Bustio) to La Hermida
brought the driving time down to 40 minutes. Still raining, so the
planned walk to create a ‘SampleGPX track’ for MapGazer » became a drive from La Hermida to Bejes (track). Then to Potes, where the rain finally stopped, to buy a
map, etc. Given the improvement in the weather and not feeling like
going further south, we backtracked and headed north and east via
La Fuente to
Toyu determined to locate the oriental (NE) upper entrance.
First approach (direct up from the road) didn’t work, and nor did
the second (down from cart track above). However, the third (west
from the cement track) was successful: Bill found the small cliff
face and Mike confirmed a draughting cave. Mike descended to almost
out-of-daylight and confirmed it was the Toyu entrance; its GPS position
Δ was within about 12m of that predicted,
well within error bounds of GPS and the estimate. “Always carry
a spare light” proved its value when Mike’s main lamp went – literally
– on the blink.
Cueva Toyu, inside NE entrance
Well pleased, and with the wet weather blues firmly banished, we
continued on to Casa Gloria for another pleasant menú. Back
to Llanes via Pendueles.
A bright morning. Off to Buelna to Cobigeru inland beach and its
cave for a more thorough exploration and wearing more appropriate
clothes and helmets. Low tide. We took photographs of the sea funneled
into the cave and creating a spectacular spray (and lots of noise!).
Noticed that the rocks in sight of daylight were often green or purple
which Bill attributed to salt-loving algae and photosynthetic bacteria.
The purple was more common in wetter zones. Some interesting ecology
Inside Cobigeru cave
After an hour underground we made some rough measurements of distance
and bearings to be able to retrace our footsteps on the surface and
found ourselves on the cliff above the lower entrances, 135m from
the inland entrance. We had underestimated the length of the system,
which we now guess to be at least 200m (rather than 70m).
Cobigeru Cave – sea breaking
Drove west on the “new” autovía to Posada and on to El Mazuco descending
the cement-surfaced track towards Bolugo sink. After the rain there
was a lot of water and there were a number of distinct streams draining
the depression. This also meant that the tracks were very muddy
and slippery, but the undergrowth was mainly dry. Our object was
to GPS the Boriza resurgence but access was inhibited by the difficult
terrain, (woodland, brambles, bracken, mud, barbed wire). We probably
arrived within 50m of the entrance before retracing our footsteps.
We now had worked up quite an appetite, so lunch (chuletillas!)
in Roxin and return to Llanes.
Cliffs over Cobigeru cave
Nice weather, and with caving planned for Monday we eventually decided
to have a closer look at the Pechón peninsular (NE of Unquera)
visited by Bill some years ago. The small white roads shown on the
map were drivable, and by luck we chose the right way around them
– it turned out they are a one-way system starting June 15. We
explored a closed depression, La Hoya (NE of Pechón), on foot.
On the Pechon peninsular
a house occupied the exact place we predicted a cave, leading us
to speculate that there was a cave there, leading down to a sea cave.
Pijota at Casa La Aldea
The western end of the peninsular proved to be inaccessible, so we
retreated to Comillas for lunch; a reprise of 2014:
spectacular pijota a la plancha (baby hake) and chiperones
en su tinto at Casa La Aldea.
||Welcomed by a bright blue sky we had a good breakfast at Cafeteria El Latino then drove east to Venta de Fresnedo for some caving in Toyu.
After changing, Mike GPSed Δ the “Torca”
behind the barn but did not descend as it was partially filled with
tree branches. We retraced our steps along the track and turned
south to the other top entrance through the gorse, brambles, and
nettles we had thrashed through on Friday.
Bill descended first wearing his bright red shorts which rapidly
became quite muddy as he insisted on chimneying down the easy entrance
climb. We were both soon in the dry large chamber with various passages
descending on the left, and some ascending on the right. This was
the cave we had not entered in 30 years!
Inside Cueva Toyu
After some difficulty route finding, we found our old route down
via the second passage on the left. It seems some subsequent explorers
(Carlos Puch?) had made little cairns of stones to mark the route.
Nevertheless route finding was not easy but after 15 minutes we came
to the climb marked as 5m on our 1982 survey. In those days this
was an easy free climb (particularly when wearing rubber wetsuits).
But 34 years later a hand line or ladder was thought necessary so
we turned back to search for the “Torca” entrance and make a through
trip. Back to the chamber ... but there were many possible passages
We separated (remaining in voice contact) trying various routes and
consulting the printed survey which Mike had thoughtfully taken underground.
All to no avail. It looks like we will have to descend the Torca
another year to make the through trip. Spent about 1 hour underground.
Changed, and drove to Urdón to look at the famous (The Highlands
of Cantabria, Ross & Stonehewer Cooper, 1885) cave entrance there
Δ about 30m from the Tresviso path
and the main road. We had not visited it before, and it turned out
to be just 5m long so we could not even get out of sight of daylight!
It was now 14:00 so we drove back south to La Hermida and enjoyed
their €12 menu del día. Back to Llanes via Posada.
||Evening flights in effect allowed a full day of activity, but with
gear packed reconnaissance was in order. Anxious to re-sample the
lamb at Espinosa de los Monteros remembered from 2005
we chose a route via Torrelavega, Puente Viesgo, Vega de Pas, and
Pto. de las Estacas. On arrival at Vega de Pas, however, we found
the road over the pass closed for roadworks. Choosing the shorter
of two long options, we rerouted via Selaya and Portillo de Lunada
(1,350m). We were rewarded with spectacular views, limestone, and
even a little snow. Arriving in Espinosa on-schedule at 14:03, we
found (we think) the 2005 restaurant (Sancho García) in the main
square; hard to find as it was market day and the square was full
of stalls and vans. Lunch was exceptional for a menú (€10.50),
with paletilla (shoulderblade) of lamb being the highlight.
en route to Portillo Lunada
On to Ramales to see if it would make a suitable base for 2017 (on
the to-do list because of trips there in 1977), but it didn’t inspire.
Ditto for Laredo, after a ‘10 minute’ diversion to check it out.
Next to Solares to fill tank, etc., before arrival at Santander airport
– again on schedule at 18:30. A very full day, with lots of driving
for Bill over quite exposed mountain roads.
Bill made it home at 02:00, Mike got to Stansted hotel (after an
hour in passport queue) at 01:00.
