Day by day

Open the plan when you need the detail.

Start with the short version. Open a day when you want the fuller story, the timings, the moving parts, and the useful practical bits.

Day 1Friday

Landing at Bilbao and the drive west

A flight, a rental car, and under two hours of motorway before the week actually starts.

Flight Into BilbaoDrive Bilbao to Santillana del Mar on the A-8, about 1 hour 45Stay Villaverde Village
Nothing is asked of day one except arriving. Pick the car up at Bilbao and drive west on the A-8, which runs the length of this coast a ridge inland from the sea — an hour and three quarters, no passes, no navigation worth the name. The country changes on the way and it is worth watching: the industrial approaches to Bilbao give out into the wet, folded, aggressively green landscape that earns northern Spain its nickname, with the Picos somewhere south behind whatever cloud is in the way. Arrive late afternoon, work out where the loungers are, and let the week start tomorrow. Dinner in Santillana del Mar chosen on effort rather than merit, because the only job tonight is to stop moving.

Getting there

  • Collect the rental car at Bilbao airport.
  • West on the A-8, straight through.

Landing

  • Arrive late afternoon, unpack, and stop.
  • First dinner in the old town, low effort by design.

Planning notes

  • Check-in is autonomous, so arrival time is flexible and nobody needs to be met.
Day 2Saturday

Santillana and Altamira

The old town before the coaches, the painted ceiling at Altamira, and an afternoon with nothing in it.

Day two starts gently on purpose. is a genuinely beautiful medieval village that has been thoroughly discovered — cobbles, a Romanesque collegiate church, stone houses with wooden balconies — and for about two hours each morning it belongs to whoever is already standing in it. After that the coaches arrive. So the morning is a walk through it before that happens, and a coffee on the way back. The anchor is , two kilometres out of town. What you actually visit is the , an exact replica built beside the real cave, which has been closed for decades because the breath and body heat of too many visitors began damaging paintings that had survived at least fourteen thousand years. That sounds like a compromise and partly it is, but the effect in the low chamber is the intended one: a ceiling crowded with bison, painted by people who used the bulges in the rock to give the animals their shoulders and haunches. Then lunch, and an afternoon with nothing in it.

The first morning

Open any place below for the fuller background behind the route.

Fixed points

  • - Booked ahead; the only thing the day is committed to.

Early

  • Walk the old town while it is still quiet.
  • Coffee somewhere on the way back.

The anchor

  • , a few minutes out of town.Fixed

The rest of the day

  • Lunch, then deliberately nothing.
  • An easy first proper dinner.

Planning notes

  • slots are limited and sell out well in advance, so this is the one booking that shapes the morning.

Optional ideas

  • The Colegiata de Santa Juliana, if the Romanesque church is worth more than the walk past it.
  • Nothing at all after lunch — the garden and the loungers are a legitimate use of day two.
Day 3Sunday

Comillas and San Vicente de la Barquera

A Gaudí folly at midday, then a harbour lunch and a castle above the estuary.

Two towns, both taken at strolling pace. first, early enough to have it to yourself — a small town that became improbably grand in the nineteenth century when its emigrants came back rich from the Americas and spent the money on architecture. The anchor is , which Gaudí built here in the 1880s for one of them: a summer villa banded in sunflower tiles with a tower like a minaret dropped into a Cantabrian garden, and one of only three buildings he ever completed outside Catalonia. It is small, strange, and takes about an hour. Afterwards the road runs fifteen minutes west to , which sits on an estuary behind a long bridge with a ruined royal castle on the hill above it. Lunch by the harbour — sorropotún, the tuna and potato stew the town is known for, if anyone is making it — then the castle, the estuary, and a walk with no particular destination.

Money from the Americas

After

  • West to and a late harbour lunch.
  • The castle, the estuary, and no fixed time to leave.

Practical tips

  • Park at the municipal polideportivo in — free, rarely full, and ten minutes on foot from .
  • The bakeries in sell corbatas, a twisted puff pastry worth carrying home in a paper bag.

Optional ideas

  • Oyambre beach on the drive back, if the afternoon is holding.
  • The rest of — the Sobrellano palace and the old pontifical university are visible from most of the town and free to walk around.
Day 4Monday

El Soplao and the road into the hills

An hour underground in one of the odder caves in Europe, then a mountain village and whatever the afternoon wants.

The only early start of the week, and it earns it. was found in 1908 by miners cutting into the hillside for zinc and lead, which is the usual way these things happen, but what they broke into is unusual even by cave standards: the chambers are full of eccentrics, thin mineral filaments that grow sideways and upward against gravity in defiance of how a cave is supposed to work. The tour runs about an hour and is in Spanish only, which matters less than it sounds — the guide talks, and the cave does the rest. Afterwards the day turns rural. is a small stone village in the hills with almost nothing in it, and the point of going is that it feels nothing like the coast twenty minutes away: darker timber, steeper ground, kitchens that cook chicken with paprika and ham rather than anything out of the sea. Then either a river walk or a slow drive back, depending entirely on how the legs feel.

Underground and inland

Open any place below for the fuller background behind the route.

Fixed points

  • 10:00 , Visita Turística - Booked; about 55 minutes, Spanish only.

The anchor

Midday

  • Up to — a short walk around it is the whole village.
  • Lunch there if the kitchen is open.

Whichever way the afternoon goes

  • The Nansa valley on foot, or the same valley through a windscreen.

Planning notes

  • Rural kitchens inland keep their own hours and can be shut on a weekday, so lunch in is worth confirming before driving up.

Optional ideas

  • The Valle del Nansa river path, roughly six kilometres out and back through chestnut woods.
  • The valley road back to the coast at half speed, with a coffee stop and an early afternoon at the house.
Day 5Tuesday

Santander, slowly

A headland walk, the local lunch hour around the Mercado del Este, and no fixed time to come home.

gets a morning and no plan beyond it. The first, early, when it is just sea and joggers and nobody selling anything — a headland with a royal summer palace on it and a path around the edge that takes an hour if you dawdle. Then a slow drift inland as the bars around the Mercado del Este start setting up, which they do towards lunchtime and not a minute before. What follows is the anchor, and it is the one anchor of the week that nobody booked: the . You stand, you point at what looks good, you pay a couple of euros, you move to the next place. — squid rings fried crisp, lemon, nothing else — are the standard order and a fair test of any bar. After that the day has no opinion. Another neighbourhood, a coffee with a view, or the drive back the moment it stops being fun.

The city and its lunch hour

Open any place below for the fuller background behind the route.

Early

  • Drive in and walk the before the day warms up.

Around one

  • Drift towards the Mercado del Este as the bars open.
  • Eat standing, a couple of things at a time, and keep moving.

Open end

  • Stay as long as it stays interesting.
  • Drive back whenever.

Practical tips

  • The bars near the Mercado del Este do not get going until close to lunchtime, so arriving early just means an empty street.

Optional ideas

  • MUPAC, the prehistory museum under the Mercado del Este, which follows on well from Altamira.
  • The market itself, for cheese and a browse rather than a meal.
  • A second neighbourhood, if the city is holding your attention.
Day 6Wednesday

Santoña and the anchovies

A free factory tour, a working fishing port with no tourists in it, and the coast road home.

Santoña is forty-five minutes east, past the that make up one of the better bird reserves on this coast, and it is the least decorated place on the whole itinerary. It is a working port that happens to produce what most of Spain agrees is the best in the country. The tour at the cannery is free, runs every hour, needs no booking, and is genuinely interesting: the fish are salted and pressed and left for months before anyone touches them again, then filleted by hand, one at a time, by women who have been doing it for decades. There is a tasting at the end — the salt-cured fillets in oil, and the paler in vinegar, which are a different thing entirely and worth trying side by side. Afterwards the town: a harbour, a fort above it, no gift shops to speak of, and lunch on the waterfront. The drive back can take as long as you let it.

Getting there

The anchor

  • The tour — film, factory floor, and a tasting at the end.
  • Try the as well as the salt-cured fillets.

The rest

  • Harbour walk, the fort, and lunch on the water.
  • Home slowly, with or without a beach on the way.

Practical tips

  • The tour runs hourly through the late morning and takes no reservation, so going on the first one means a smaller group.

Optional ideas

  • Noja or Trengandín on the coast road back, if a beach stop appeals.
  • The fort above the harbour, for the view rather than the history.
Day 7Thursday

A day with nothing in it

No anchor, no drive, no obligation — and the one day the coast gets to explain itself.

The Ermita de Santa Justa above the cove at Ubiarco, highlight for day 7
This is the day the week has been building towards, which is to say it contains nothing. It is also the right moment to say what this coast actually is. Cantabria is the wet green edge of Spain, a two-hundred-kilometre strip where the mountains come down almost to the water — the Picos de Europa are barely thirty kilometres inland, which is why the weather arrives so fast and why the grass is the colour it is. It never became a resort coast. It stayed dairy country and fishing country, and the result in September is a shoreline with proper sand on it and nobody standing on the sand. The food divides along exactly the same line as the geography: anchovies and hake and squid on one side of that thirty kilometres, and on the other, bean stew with blood sausage, beef from a mountain breed, cheese aged in caves. Somewhere in the middle sits , the dense baked custard that every restaurant makes slightly differently, which is as good a reason as any to order it twice. Today is for a beach or a lounger, and no further plan than that.

The coast itself

Open any place below for the fuller background behind the route.

If the weather holds

  • , ten minutes away — a small cove with a rock arch and usually nobody in it.
  • Or , twenty-five minutes east, where the limestone breaks up into towers and pools.

If it does not

  • The garden, the jacuzzi, and no apology for either.
  • Or drive somewhere on impulse, on the grounds that nothing is booked.

Practical tips

  • Tonight is the last proper dinner of the trip, so it is the one worth booking a day ahead.

Optional ideas

  • Llanes, an hour west into Asturias — a walled old town, a working harbour, and the painted concrete blocks on the breakwater, which are better than they sound.
  • Castro Urdiales, an hour and a half east, for a Gothic church on a sea cliff and a quieter coastline.
Day 8Friday

Departure

Last coffee in the old town, the coast road back east, and a car to hand over at Bilbao.

Departure morning on the Cantabrian coast highlight for day 8
Drive Santillana del Mar to Bilbao airport, about 1 hour 45
The last morning is a transfer with a coffee in front of it. Pack, walk the old town once more while it is still quiet, and then the A-8 back the way it came — the same hour and three quarters, the same green, in the opposite direction. The only thing worth watching is the clock at the far end.

Last morning

  • Breakfast, packing, and a final walk through Santillana.

East along the coast

  • The A-8 back to Bilbao.
  • Return the car with time in hand, then fly.

Planning notes

  • Car returns at Bilbao airport back up badly at peak times, so the schedule wants twenty or thirty minutes of slack in it.
