Two beaches, one bay, and a wave that the regional tourism board openly recommends for the days when the rest of the coast is unusable. Plentzia and Gorliz sit at the end of metro Line 1, in the mouth of a river, where the Bay of Biscay breaks offshore instead of on the sand.
What are Plentzia and Gorliz beaches like? Plentzia and Gorliz are two sheltered bay beaches at the end of Metro Bilbao Line 1, joined by a promenade of about 1,500 metres. Gorliz runs 842 metres, according to Turismo Euskadi, and the white footbridge at Plentzia crosses the estuary in 117 metres. Lifeguards cover 11am to 8pm in summer.
The Bay of Plentzia is a natural inlet at the mouth of the Butroe estuary, and it holds two beaches joined by a single promenade. They mark the end of Line 1 on the map of beaches near Bilbao without a car.
The calm-water beach on a rough day
Sheltered water is the whole point of this bay, and the Basque Government says so in writing. Its tourism board describes the Plentzia wave as one of the best alternatives when conditions are adverse and the sea is out of shape, calling it a long, manageable left. For a visitor, that is an official answer to the question of where to go when the forecast ruins the plan.
The same board describes Plentzia as calm water suited to families with children, and Gorliz as preferred by families for its wide sands and the safety of its bathing. Neither description is marketing filler: both beaches sit inside the bay, so the swell that hits the open coast at Sopela arrives here already broken.
That makes this the fallback for the whole stretch. If you were heading for Sopelana beach on metro Line 1 and the swell turns, three more stops fixes the day at no extra fare.
What it costs and where to get off
Plentzia and Gorliz sit in fare zone 3, the same zone as Sopela, according to the Diputación Foral de Bizkaia, which publishes the zone map. A three-zone metro ride costs €1.30 on a Barik card and €2.25 on a single ticket according to the Consorcio de Transportes de Bizkaia, so riding to the end of Line 1 costs exactly the same as stopping halfway.
Biscay’s provincial tourism board assigns both beaches to Plentzia station on Metro Bilbao, which is also the terminus. There is no way to miss your stop, and it is the last beach in the province the metro reaches.
Plentzia beach sits beside the old town, a short walk from the platform. For Gorliz there are two options: the promenade around the bay, or the bus linking Gorliz town centre with the station.
Gorliz has the services
Gorliz runs 842 metres through the middle of town, ringed by a promenade, according to the Basque Government tourism board. It was the first beach in the Basque Country certified with the Q for Tourist Quality, and it carries free wifi.
What separates it from the rest is everything off the sand: wide parking at beach level, green areas with tables, benches, barbecues and playgrounds. For a long day with small children that matters more than the beach itself. Lifeguards cover 11am to 8pm in summer.
In the water there is surf, sailing, kayaking, big SUP and coasteering. Around it stand the old Marine Sanatorium, now part of the public hospital network, the Gorliz lighthouse, and the Granja Foral, Biscay’s wildlife recovery centre, which works among other things with the pottoka, the native Basque pony.
Plentzia has the town
Plentzia beach has a historic old town at the edge of the sand, and that is its advantage over Gorliz. It is fine golden sand inside the bay next to the river mouth, also ringed by a promenade, with lifeguards covering the same 11am to 8pm.
The town supplies what a beach cannot: narrow old-quarter streets, the Arco de Santiago, the Puerto La Gallarda, a former commercial and fishing harbour sheltered inside the estuary, and the Gazteluondo park with its tidal mill, which stored water at high tide and released it as the sea dropped. The Plentzia footbridge, a white span of 117 metres, crosses the estuary and is the image the town is known by.
For surf, Plentzia has two schools operating all year, according to the Basque Government. It is not a big-wave beach, and that is precisely why it works for learning.
| Beach | Length | Best for | Assisted bathing | Main limitation |
|---|---|---|---|---|
| Gorliz | 842 m | Long family day, barbecues, parking | Yes | Further from the station than Plentzia |
| Plentzia | n/a | Old town at the sand, learning to surf | Yes | Less leisure equipment around it |
| Arrietara-Atxabiribil, Sopela | 826 m | Open coast, sunsets | No | Strong swell, no assisted bathing |
| Ereaga, Getxo | 882 m | Zone 2, urban setting | Yes | Neither open coast nor closed bay |
Booking assisted bathing before you travel
Both beaches in this bay run the Provincial Council’s assisted bathing service, which is unusual: of the beaches Line 1 reaches, only Ereaga, Plentzia and Gorliz have it. The Diputación Foral de Bizkaia runs it at eight beaches across the province, the others being La Arena in Zierbena, Arrigorri in Ondarroa, Isuntza in Lekeitio, Laidatxu in Mundaka and Bakio.
The service covers two different things: personal assistance into the water, and loan of equipment for people who are largely independent and only need support. That equipment includes beach access chairs, hoists, walking frames, crutches and buoyancy vests. It runs across June, July, August and September.
Booking works three ways, and this is the part worth sorting before you fly. The Provincial Council’s Citas Previas site takes bookings from 30 May to 30 September; the phone line is 662 92 13 97; and you can also book at the desk in the beach marquee once you are there. Associations and organised groups have to book online.
The promenade that joins the two beaches
A promenade of roughly 1,500 linear metres links Plentzia beach with the Astondo breakwater in Gorliz. The Spanish Ministry for Ecological Transition describes it within its works to reshape and manage the Gorliz and Plentzia beaches.
It is nine metres wide, split into about six metres of pedestrian walkway and roughly three metres of shared cycle lane. In practice that turns the two beaches into a single visit: arrive by metro at Plentzia, walk the bay, and finish at the other end without retracing your steps.
It also means switching beaches mid-afternoon costs nothing but the walk. When the tide narrows one strip of sand, the other is a stroll away.
The dates that catch visitors out
Almost everything described here is seasonal, and the calendar is tighter than most visitors expect. Lifeguards cover 11am to 8pm, and the Provincial Council only publishes live flag colour, occupancy and swell during those same hours. Check at nine in the morning and the system returns nothing.
Assisted bathing runs across June to September, with the booking channels open from 30 May to 30 September. Outside that window the beaches stay open and the promenade still works, but there is no lifeguard cover, no live flag data and no equipment loan.
Bathing season aside, the bay is the one part of this coast that still functions in bad weather. The promenade, the old town and the 117-metre footbridge do not close, which makes Plentzia a reasonable winter afternoon when the open beaches are unusable.
Frequently asked questions about Plentzia and Gorliz
How do I book the assisted bathing service in advance?
Through the Provincial Council’s Citas Previas booking site, open from 30 May to 30 September, or by calling 662 92 13 97. You can also book at the desk inside the beach marquee. Associations and organised groups must book online rather than by phone.
Where can I learn to surf near Bilbao as a complete beginner?
Plentzia. According to the Basque Government tourism board, the beach has two surf schools operating all year and a long, manageable left-hand wave suited to learning. It also names Plentzia as the best alternative when swell conditions elsewhere on the coast turn rough.
Are the beaches worth visiting outside the summer season?
The bay is, more than the open beaches. Lifeguards, live flag data and assisted bathing all run only from June to September, but the 1,500-metre promenade, the Plentzia old town and the 117-metre footbridge stay open year round, and the two surf schools operate all year.
Which beach near Bilbao is best for small children?
Gorliz. The Basque Government tourism board highlights its wide sands and safe bathing, with 842 metres of beach, parking at the sand, green areas with tables, benches, barbecues and playgrounds, and free wifi. It was the first beach in the Basque Country to earn the Q for Tourist Quality.
The Bay of Biscay does not calm down inside the Bay of Plentzia. It simply stays outside, which is the entire reason to come here.
