Everyone visiting Bilbao ends up with the same shortlist: the Guggenheim, a walk along the Nervión, pintxos in the old town. There's one more experience that belongs on that list, and most visitors — even locals living twenty minutes away — still haven't heard of it. It's tasting a wine that spent months ageing 18 metres beneath the Cantabrian Sea, with that same sea right in front of you as you drink it.
That's not a marketing line. It's literally what you can do at Crusoe Treasure, in Getxo's marina, and it's not something you can do anywhere else on the planet.
Why "must-know" isn't an overstatement here
We say this without exaggeration: there is no other visitable underwater artificial-reef winery in the world. A handful of other projects have experimented with submerged wine, but none combine what Crusoe Treasure does — a facility open to the public, inside a working marina in a European city, reachable by metro without renting a car or booking a tour in advance.
That last point matters more than it sounds. It turns the visit into something rare in the wine world: an experience you can decide to do on the same morning you think of it. Leave the Guggenheim mid-morning, take the L1 metro to Algorta, walk ten minutes downhill toward the marina, and — with zero advance planning — you're holding a glass of underwater-aged wine looking out at the Cantabrian Sea.
What you'll actually find there
The exhibition and the 360° immersive room. Before the glass comes the story: how the project began in 2008 under the scientific oversight of the LSEB marine research station in Plentzia, what the submerged structures actually look like, and how, over the years, they've grown into a living artificial reef. The immersive room takes you down to the seabed without getting wet.
The comparative tasting. This is where people stop listening and start understanding. The same wine, two lives: one aged on land, one aged under the sea. Poured side by side, the difference doesn't need explaining.
The wine bar overlooking the marina. No booking required — a glass, sea view, no rush. It's the twenty-minute plan that regularly turns into two hours.
The shop, with bottles that genuinely exist nowhere else. This is where you can buy bottles recovered directly from the seabed, carrying the textures and markings only the ocean can leave behind. No two are alike, so whatever you take home is, quite literally, one of a kind.
Meals, live showcooking, and events for up to 150 guests. From a paired dinner overlooking the marina to a corporate away-day built around a tasting — few team-building activities generate as much conversation as a wine that spent a year underwater.
Who this is actually for (spoiler: you don't need to know wine)
Visitors tell us this constantly: they arrive unable to tell a tempranillo from an albariño and leave asking questions about wine they'd never thought to ask before. The story doesn't require jargon, and the comparative tasting is built to be understood by the senses, not the textbook. If you already know wine, even better — you'll leave questioning a few things you'd taken for granted.
It's also, increasingly, a favourite stop for cruise passengers arriving in Bilbao: Getxo's cruise terminal sits just 300 metres from our door. No other cruise port in Europe has an underwater winery within walking distance.
What sets it apart from a standard winery visit
A Rioja or txakoli winery shows you a process you can already picture: barrels, cellar, ageing room. At Crusoe Treasure, the actual ageing process happens somewhere you can never physically stand — the bottom of the sea — which is exactly what the immersive room and the comparative tasting are built to solve. We're not competing with the wineries of Bizkaia or Rioja Alavesa; by design, we're telling a story they simply can't tell.
FAQ
Why is Crusoe Treasure considered a unique wine experience? It's the only visitable underwater artificial-reef winery in the world, ageing wine on the seabed of the Cantabrian Sea, with a comparative tasting that lets you try the same wine aged on land and underwater — something no other winery offers.
Can you get there from Bilbao without a car? Yes — it's actually the easiest way: take metro line L1 to Algorta, then walk about 10 minutes to Getxo's marina.
How long does a full visit with tasting take? Around 90 minutes. The exhibition alone can also be visited at your own pace, without a tasting.
Is it a good stop for cruise passengers arriving in Bilbao? Yes — Getxo's cruise terminal is just 300 metres from our entrance, making it the closest possible stop on any northern Spain cruise itinerary.
Do you need to book in advance? Yes, for the tasting, guided tour, meals, showcooking and events. The wine bar and shop are walk-in, though it's worth checking opening hours.
Do you host private or corporate events? Yes, for groups of up to 150 people: product launches, corporate days, tasting-based team building, and private celebrations, with in-house catering.
