The Cantabrian Sea in Bareyo isn't just for surfers. The Ría de Ajo — the estuary separating Bareyo from Noja and Isla — has calm waters, gentle tides and protected marshland, exactly what you need to go kayaking or paddleboarding near Bareyo with no previous experience required.
Less than 20 minutes by car, there are three operators who rent equipment or guide trips along the estuary, from a single hour to a full guided route. We cover all three, with indicative prices and what's worth knowing before you get in the water: when to go, what to bring, and which option suits each type of group best, from a couple who wants to paddle on their own to a family with kids who'd rather go guided.
Why the Ría de Ajo is perfect for paddling
The Ría de Ajo opens right next to the Marisma de Joyel, part of the Santoña, Victoria and Joyel Marshes Natural Park, the most important wetland on the Cantabrian coast, with more than 130 recorded bird species. Water flows in and out with the tide, so there's almost never any swell inside the estuary: perfect for anyone starting out with kayaking or stand-up paddleboarding.
Unlike surfing at Ajo beach, there's no wave to fight here. It's flat water for most of the route, with stretches of gentle current depending on the tide — one more reason to go with a guide the first time. It's also an outing that pairs well with birdwatching: herons, cormorants and waders are a common sight on the sandbanks left by the low tide.
Nojactiva, in Noja — kayaking near Bareyo with rentals and guided routes
On the seafront promenade in Noja, about 15 minutes from Bareyo, Nojactiva rents single and double kayaks for exploring the estuary independently, as well as running guided routes for anyone who'd rather go with company. They ask for ID for rentals, and minors need authorisation from an adult.
Hourly rental is the most flexible option if you just want to try it for one afternoon without committing to a fixed-schedule route; guided routes, on the other hand, make sure you don't miss the corners of the marsh that are hard to find on your own.
Sup Isla — guided paddleboarding on the Ría de Ajo
Sup Isla, based in the village of Isla, offers guided stand-up paddleboarding (SUP) trips of around two hours along the Ría de Ajo, starting with a short technique session before heading onto the water. The local guide explains how to paddle and stand on the board, so it works just as well for anyone who's never tried paddleboarding before.
Trips run in small groups and usually include a photo record of the route, a nice touch if you're going with kids who already stand confidently. Since it's a guided activity from start to finish, it's the option that leaves the least room for error if you're going with people who've never stood up to paddle before.
Loredo Aventura — kayaking at several points along the coast
Loredo Aventura doesn't have a fixed base on the Ría de Ajo, but includes it among its canoe and kayak rental points alongside Santander, Somo, Pedreña, Noja and Isla. The price includes a life jacket, dry bag and civil liability insurance, with the option to rent by the hour, day or week.
It's worth considering if you're moving between several points along the coast during your stay and would rather not depend on a single pickup location, or if you fancy combining a day of kayaking on the Ría de Ajo with another in Somo or Santander bay without switching provider.
What you need to know
Best time of year: April to October, when the water is warmer and there's less wind. July and August are the busiest booking months, so it's worth booking ahead in high season.
With kids: a double kayak with an adult is the safest option for the youngest ones; paddleboarding on the Ría de Ajo, with its calm water, works well from around age 8-10 with good balance.
Tide: it's worth checking the tide tables before heading out. When the estuary is empty, some stretches don't have enough water to paddle through, and at full high tide the incoming current can be more noticeable than expected if you're going unguided.
What to bring: swimwear, water shoes (some operators lend them), a towel and water-resistant sunscreen. The technical gear — kayak, paddle, life jacket — is always provided by the operator.
Bookings: in high season, especially weekends in July and August, it's worth booking two or three days ahead; on weekdays there's usually availability from one day to the next.
On the Ría de Ajo, you don't need to fight a wave to have a good time on the water. Just let the tide carry you along.
Between surfing at Ajo beach and quiet paddling on the estuary, Bareyo has both faces of the Cantabrian Sea within reach: the wild and the calm. If you'd rather ride waves, we've also covered where to learn to surf near Bareyo.
The Ría de Ajo is also visible from several of the villas at Bareyo Residences, which will open its doors in September 2027.
