Quick answer: La Concha is the most central and sheltered of San Sebastián’s three main urban beaches. Ondarreta suits a relaxed beach day and has a children’s play area on the sand. Zurriola, in Gros, is the city’s surfing beach and is generally more exposed to waves and currents. Sea conditions change with the tide and weather, so check the municipal bathing notices before swimming.
Donostia / San Sebastián has three main city beaches: La Concha, Ondarreta and Zurriola. Seafront promenades connect them, but each offers a different setting. This guide compares the beaches, helps you choose one for your plans and brings together practical advice. Santa Clara Island has a small seasonal beach of its own; it is separate from these three and access depends on boat services.
San Sebastián’s three beaches at a glance
| Beach | Location and atmosphere | A good choice for | Keep in mind |
|---|---|---|---|
| La Concha | Central San Sebastián, inside the bay | A first swim, a seafront stroll and combining the beach with the city centre | The tide changes the width of the sand and the space available |
| Ondarreta | Western end of the bay, beside El Antiguo | Families, relaxing on the sand and visiting Miramar or Igeldo | Currents can occur; check the flags and local advice |
| Zurriola | Gros, east of the Urumea River | Surfing, an energetic atmosphere and beach sports | More exposed to waves and currents; follow lifeguard instructions |
This is a general guide, not a forecast for a particular day. The city council describes Zurriola as the beach with stronger waves and currents. La Concha is more sheltered, although tides still matter; Ondarreta can also have lateral currents. Read the city’s official safe-bathing advice before you go in the water.
La Concha Beach: the central beach in the bay
La Concha curves around the centre of the bay, from the City Hall area to the Pico del Loro, the rocky point separating it from Ondarreta. Its average length is about 1,350 metres. The seafront promenade, views of Santa Clara Island and proximity to the Old Town and city centre make it easy to include in a city visit.
Choose La Concha if you want to swim without travelling far from the centre, walk along the promenade or stop at Alderdi Eder Gardens. The bay offers more shelter than Zurriola, but that does not mean the sea is always calm: tides affect the beach and currents may occur. Check the flags and daily notices before entering the water.
At low tide, a rocky passage at Pico del Loro may be exposed between La Concha and Ondarreta. Do not rely on it as a permanent route: the tide covers parts of the passage again. The city promenade is the dependable way to continue along the coast. For more detail, see our guide to La Concha Bay.
Ondarreta Beach: sand, play area and the western end of the bay
Ondarreta lies west of La Concha, in El Antiguo, below Mount Igeldo and beside the gardens of Miramar Palace. It is about 600 metres long on average and often feels quieter than the central part of the bay. The official tourism site notes that there is a children’s play area on the sand.
From here, you can combine time on the beach with a walk to the Peine del Viento sculpture or a trip up Mount Igeldo. The location makes it easy to plan a varied outing without spending the whole day on the sand. Check the flags and sea conditions before swimming; the bay’s sheltered position does not rule out lateral currents.
Municipal beach services operate during the official season. Showers, toilets, lifeguards, parasols and assisted bathing may depend on the date and change from year to year. Check the city’s current beach information before your visit.
Zurriola Beach: surfing and Gros neighbourhood life
Zurriola is in Gros, east of the Urumea River mouth, facing the Kursaal and close to Sagüés. It is the beach most closely associated with surfing in Donostia. Surf schools operate here and events are held on the beach; availability and conditions depend on each provider and the time of year.
Waves and currents can change, and are generally stronger here than at the other two beaches. That draws surfers and visitors who enjoy an active seafront, with Gros’s cafés and shops close by. If you are not experienced in the sea, ask a local surf school about the day’s conditions. Follow the lifeguards’ instructions and swim only in the areas and at the times indicated.
The beachfront walk links Sagüés with the Kursaal cubes and continues along the Urumea or towards the Paseo Nuevo. See our Three Beaches Promenade guide for a longer route.
Which San Sebastián beach should you choose?
- For a swim close to the city centre: La Concha is next to the Old Town, City Hall and the bay promenade.
- For a family beach day: Ondarreta has a children’s play area on the sand and is near Miramar and Igeldo. Check the sea conditions and services first.
- For surfing: Zurriola. Check the sea report and follow advice from the surf school or lifeguards.
- For a coastal walk: follow the bay promenade and continue towards Gros. This is an urban route with different stretches of coast and viewpoints.
- For more room on the sand: check the tide and expected crowds. The available sand changes, especially at La Concha.
If your plans depend on a specific service—assisted bathing, parasol hire, showers, toilets or lifeguards—check that it is operating on your date. The municipal beach season has set dates, and the city publishes current details on its beach-season page.
How to walk between the three beaches
A straightforward way to see them is to start at La Concha and follow the seafront promenade towards Ondarreta. From the western end, you can continue to the Peine del Viento. To reach Zurriola, return along the bay, cross the centre and follow the Urumea River to Gros. It is an urban coastal walk with promenades, rocky sections and open views; the whole route does not run along the sand.
The Pico del Loro passage between La Concha and Ondarreta depends on the tide. If it is covered, or you prefer to avoid the rocks, use the promenade. Our Three Beaches Promenade guide explains the route in more detail. Wear comfortable shoes and leave time for stops—the neighbourhoods and scenery are part of the walk.
Practical advice before going to the beach
Check the tide, waves and beach flags
The beach can look different within a few hours. At La Concha, the tide affects the amount of sand and access towards Ondarreta. At Zurriola, waves and currents need particular attention. Follow the flags and lifeguard instructions. The city council publishes safe-bathing advice.
Check which services are operating on your visit date
Beach services are not available every day of the year and their hours can change. Toilets, showers, lifeguards, parasols and assisted bathing may be seasonal. Check the city’s current information before travelling, especially if you need an accessibility service.
Find out about accessibility
La Concha has a municipal assisted-bathing service during part of the high season. Dates, hours and equipment are updated each year. Check the city’s assisted-bathing information before your visit.
Check the current beach rules
Rules on smoking, sound equipment, dogs and use of the sand may depend on the current municipal ordinance and season. Check official notices rather than relying on information from previous years. The beach-season page lists current notices and conditions.
Plan your journey
All three beaches are within the city and can be combined with a visit to their neighbourhoods. If you are driving, check parking options and the low-emission zone before setting off. For public transport, see our San Sebastián transport and mobility guide.
