Let's start with the thing the glossy photos won't tell you: it rains here. Cantabria is part of Green Spain, and it is green for a reason — the same weather that keeps the valley lush will, some weeks, close in for a day and put paid to the big walk. Anyone promising you guaranteed sunshine in northern Spain is selling you something. The better question isn't whether you'll get a wet day; it's what a wet day is actually like. And on a hosted, catered week, the answer is: still a good one.

First, the honest bit: it rains here

Not constantly, and rarely all week — but expect that at least the odd day will turn. The upside is written into the landscape: the oak and beech forests, the full rivers, the sheer greenness that people come for exist because this isn't the bone-dry Costa. You take the two together. Pack for it and a wet day is a minor rearrangement, not a ruined holiday.

Do walks still go ahead in the rain?

Often, yes. A bit of drizzle doesn't cancel a walk — with the right jacket and boots, a soft grey day in the forest can be one of the best of the week, quiet and atmospheric, the paths to yourselves. What does get called off is the serious high stuff when the weather makes it genuinely unwise: low cloud on an exposed ridge, slick rock on a steep descent. The distinction is always about safety, not comfort — getting damp is simply part of walking in a green valley; getting caught on an exposed ridge in poor visibility is a different matter entirely, and that's the line Walkwise are actually drawing. When they decide a mountain day is off for safety, that's not a disappointment to grumble about — it's exactly the judgement you want from people who know these hills. A guide who'd march you onto a fog-bound ridge to keep to a schedule is a guide to avoid.

What does a rained-off day at the house actually look like?

This is where staying in a proper house rather than a hotel between hikes earns its keep. A wet day doesn't strand you — it hands you the casona. There's the fire, the long table, books, and the underrated pleasure of doing very little somewhere warm and comfortable while the rain does its thing outside. Because it's half board, breakfast and a home-cooked dinner arrive regardless, so there's no trudging out into the wet to find lunch or fretting about where dinner's coming from — the house wine and beer are on hand too. A slow, sociable, indoor day with the other guests is one of the quiet highlights people don't expect, and Chispa the house dog is unbothered by weather either way. Some guests admit afterwards that the wet day was one of their favourites of the week — the one with nothing scheduled, nowhere to be, and the whole point simply being comfortable together.

Where to go when you would rather be indoors

A rained-off walking day is a ready-made day for the things you might otherwise not make time for. Medieval Santillana del Mar is about twenty minutes away, its cobbled streets and museums easy to duck in and out of. Comillas has Gaudí's El Capricho to wander through. The Altamira museum's Neocueva — the replica of the famous cave paintings — is indoors and genuinely worth it, though book ahead, as you can't just turn up. San Vicente de la Barquera is a fine spot for a long lunch watching the harbour through a rainy window. None of it needs the sun out, and none of it needs much planning beyond the Altamira booking — you can decide over breakfast and be there within half an hour.

You can't book the weather — but you can book for it

The practical honesty is this: bring a proper waterproof and boots that have been worn in, and a wet day becomes a choice between a moody forest walk and a cosy day of house, fire and villages — rather than a write-off. The one week you truly want to avoid a washout is a self-catering box in the middle of nowhere with nothing laid on. A hosted house with dinner cooked, drinks poured and company at the table is close to the opposite of that.
