Green Spain — España Verde — is the Atlantic north of Spain: Galicia, Asturias, Cantabria and the Basque Country, the strip of coast and mountains running between the Bay of Biscay and the dry interior. Ocean weather keeps it green all year round, which makes it unlike anywhere else in the country: cooler, lusher and far less built-up than the Mediterranean coasts.

Where does the name come from?

España Verde is the name the four northern regions use together for the coastline they share, and for once the marketing is simple description. Travel the north and the first word that arrives is the same for everyone: green. Hedgerows, oak and beech woods, dairy pasture, rivers with water in them in August. British visitors often say it reminds them of home, only warmer and with better lunches. They are usually saying it over one of those lunches at the time.

Why is it actually green?

Because weather off the Atlantic meets mountains that stand close to the sea, and the mountains collect the cloud. Rain falls through the year rather than in one violent season, temperatures stay mild in both directions, and the land responds. In our corner of it — the Saja-Besaya nature reserve in Cantabria — that means trout in the river Saja, red deer on the high ground and cattle on the lanes.

To be plain about it: yes, it rains here, occasionally even in August. If guaranteed sunshine is the whole point of your holiday, the south of Spain exists and is very good at it. What the north offers instead is shade, water, cool nights and a landscape still alive in high summer.

How is it different from the Spain most Britons know?

In almost every way that matters day to day. The food leans north: mountain cooking like cocido montañés, the local stew of beans, greens and pork; sobaos, the local butter sponges; cheeses from the dairy country; fish off the Biscay ports. The architecture is stone — balconied farmhouses and manor houses, the casonas, of which Casa Agara is an eighteenth-century example. And the tourism is small-scale: no high-rise strips, no clubbing resorts, mostly Spanish visitors. Summers are warm rather than punishing, which is why the walking season runs straight through the middle of the year instead of pausing for it. The full side-by-side is in Green Spain vs the costas.

What is there to actually do?

Walking is the headline. The trail network of the Saja-Besaya reserve starts at our door and grades honestly: the forest routes above Ucieda stay under 600 metres and suit ordinary fitness, while the Puertos de Sejos climb past 1,000 metres for those who want to earn their dinner, and the Picos de Europa wait about an hour away for the biggest days.

Beyond walking: surf beaches about forty minutes from the valley that take complete beginners; riding, including low-tide beach rides; road cycling up the Palombera pass from the front door; cave art at Altamira beside Santillana del Mar; Gaudí's El Capricho at Comillas; trout fishing on the Saja. Enough, in short, that weeks here run to themes rather than itineraries.

Does Green Spain work for a solo visit?

Very well — arguably better than the busy coasts, because the scale is human and the formula that suits solo travel best, the hosted week, is at home here. You join a scheduled group as an individual, days are escorted, dinner is shared, and the geography does the rest: even the shyest table finds conversation easy after a day of beech woods and sea air. The money is handled fairly too: no forced single supplement, meaning twin-share with a same-sex room-mate at no extra charge, the supplement covered if no match is found, or a room of your own for an optional supplement.

Where should a first visit start?

Cantabria makes the strongest practical case for British travellers: direct UK flights into Santander, Bilbao an hour and a half away, and Brittany Ferries sailing from England straight into Santander if you would rather not fly. It is also compact — from one base you can touch coast, valley and high mountain in the same week, which is precisely how walking holidays in Cantabria tend to be built.

Casa Agara is a worked example of the region's formula: an eighteenth-century casona in Fresneda de Cabuérniga where Rob and María have hosted scheduled weeks since 2023, with half board, vegetables from the garden, one long table, and a group made of guests who each booked as individuals. The weeks are booked through Spice Escapes, Casa Agara's exclusive booking partner, whose hosted holidays go back more than 45 years.
