Things to do in San Sebastián: 10 must-see sights

Julieta Betancor Julieta Betancor GuruWalk · Updated 25 Aug 2026

Plan three days in San Sebastián with the essential sights, from La Concha and the Old Town to Monte Igueldo, Peine del Viento and San Telmo Museum.

Practical details reviewed: August 2026. Opening times, admission, transport services and seasonal activities can change, so check the relevant official website before you visit.

How to spend three days in San Sebastián

Urban rooftops and distant landmarks add a city-scale counterpoint to the bay.

Three days give you enough time to enjoy San Sebastián’s historic centre, coastal scenery and food culture without rushing. This itinerary groups nearby sights together so you spend more time exploring and less time crossing the city.

Day 1: the historic heart

Begin in the Old Town, where Plaza de la Constitución, San Vicente Church and the Basilica of Santa María del Coro sit within a few minutes’ walk of one another. Continue to the port, then return to the Old Town for pintxos.

Day 2: culture and panoramic views

Visit the Good Shepherd Cathedral in the morning, followed by the San Telmo Museum. Later, take the historic funicular up Monte Igueldo for a broad view across La Concha Bay, then finish beside Peine del Viento at the western end of Ondarreta Beach.

Day 3: beaches and a slower pace

Walk the promenade beside La Concha Beach and stop at Miramar Palace. If the weather suits, spend some time on the beach. In the afternoon, choose the Aquarium or a spa session at La Perla.

Tips for a three-day visit

  • Tickets: check the Aquarium’s current admission arrangements and the Monte Igueldo calendar before setting out.
  • Getting around: the centre is compact and best explored on foot, with local buses useful for longer journeys.
  • Food: leave room for more than one pintxos stop rather than trying to order everything in a single bar.
  • Rain plan: keep the Aquarium and San Telmo Museum in reserve for wet weather.

Paseo Nuevo

The active shoreline shows the city's coastal landscape as a lived public space.

Paseo Nuevo curves around Monte Urgull between the port and the Kursaal area. The full seafront walk takes roughly 40 minutes at an easy pace, although you will probably want longer for the views.

The route is exposed to the Bay of Biscay and is famous for waves crashing over the sea wall. Treat barriers and closure notices seriously when the sea is rough. Along the way, look for Jorge Oteiza’s Construcción Vacía sculpture; Peine del Viento lies across the bay at the far end of Ondarreta.

A brief history of Paseo Nuevo

The promenade was designed in 1915 by engineer Luis Balanzat with architect Juan Rafael Alday and opened in 1919 as Paseo del Príncipe de Asturias. Its name changed with Spain’s political history before Paseo Nuevo became the official name in July 1979.

Good Shepherd Cathedral

The Good Shepherd Cathedral is the seat of the Diocese of San Sebastián. Architect Manuel Echave designed the highly vertical Neo-Gothic building, constructed between 1889 and 1897 with clear references to German Gothic churches, particularly Cologne Cathedral.

Inside, highlights include the crypt, the stained glass designed by Juan Bautista Lázaro and the large 1954 organ built by Organería Española in Azpeitia. The stained-glass programme includes scenes of the Apostles around the apse. Remember that this is an active place of worship, so visitor access may change during services.

San Sebastián Old Town

Taste San Sebastián’s legendary pintxos

Traditional streets and buildings in San Sebastián Old Town

The Parte Vieja, or Old Town, packs several of the city’s essential stops into a small area: Plaza de la Constitución, San Vicente Church and the Basilica of Santa María del Coro. Kale Nagusia, also called Calle Mayor, runs between the basilica and the edge of the district.

This is also the classic area for a pintxos crawl. Order one or two specialities, have a drink and move on to the next bar. Gildas, txangurro, salt cod and local tortilla variations are recurring favourites, while pintxo-pote promotions depend on the neighbourhood and day.

Plaza de la Constitución

Numbered balconies in Plaza de la Constitución, San Sebastián

Plaza de la Constitución stands at the centre of the Old Town and hosts major civic traditions, including the raising and lowering of the flag during the Tamborrada on 20 January. Its main Neo-Classical building dates from 1829–1832 and served as City Hall until 1947.

Look up at the numbered balconies: they recall the period when the square was used as a bullring and the balconies functioned as spectator boxes.

San Vicente Church

Dating from the 15th and 16th centuries, the Gothic Church of San Vicente is one of the city’s oldest surviving buildings. Its main altarpiece, completed in 1586, is associated with sculptor Ambrosio de Bengoechea and Juan de Iriarte.

Basilica of Santa María del Coro

Baroque facade of the Basilica of Santa María del Coro

The Basilica of Santa María del Coro was built between 1743 and 1774. Its predominantly Baroque design incorporates Gothic, Churrigueresque and Neo-Classical elements. The high altar houses the Virgin of the Choir, one of the city’s patron figures alongside Saint Sebastian.

Peine del Viento

Peine del Viento is Eduardo Chillida’s best-known public work in San Sebastián. Installed in 1976 at the end of Ondarreta Beach, it consists of three large weathered-steel forms anchored where the city meets the sea.

The surrounding plaza, designed with architect Luis Peña Ganchegui, includes openings that channel air and sound when waves enter the cavities below. Keep back from the edge in rough conditions: the same Atlantic energy that makes the site memorable can also make it hazardous.

Monte Igueldo

Historic tower and coastline seen from Monte Igueldo

Monte Igueldo provides the classic view across La Concha Bay, Santa Clara Island and the city. You can reach the top by road or on the historic funicular, which opened in 1912.

Tip: opening days, funicular times, admission and attraction prices vary. Check the official Monte Igueldo visitor information for your date, and allow extra time during busy periods.

The Torreón

At the summit, the Torreón occupies the site of an 18th-century lighthouse and now serves as a viewpoint within the park. Its terrace looks over the city and the Gipuzkoa coastline.

Monte Igueldo amusement park

The small amusement park has retained much of its early-20th-century character. Long-running attractions include Montaña Suiza, the maze, Río Misterioso and the haunted house, although individual rides may close because of weather or maintenance.

San Sebastián Aquarium

The San Sebastián Aquarium combines displays about Basque maritime history with modern tanks and an ocean tunnel. It is an easy addition to a port and Old Town itinerary, and a particularly useful option for families or wet-weather days.

Talks, feeding sessions and other activities are programme-dependent, so check what is scheduled on the day rather than assuming a particular event will be running.

Food and drink at the Aquarium

The availability and format of the Aquarium’s restaurant, café and event catering can change. Confirm the current service before making it part of your plans.

San Telmo Museum

San Telmo Museum in the former Dominican convent

The San Telmo Museum explores the development of Basque society through art, ethnography, archaeology, photography and history. Its setting is part of the appeal: a former 16th-century Dominican convent at the foot of Monte Urgull, joined to a contemporary extension.

The historic building

The convent is mainly Gothic, with a Renaissance cloister. After being damaged in 1813, it served as a barracks following the confiscations of 1836 and later became a protected monument and municipal museum.

Inside the museum

  • Collections: Basque art, history, ethnography, archaeology and photography.
  • Artists: the displays include work by figures such as Oteiza, Zuloaga and Balerdi.
  • Practical information: free-admission periods, holiday exceptions and audio-guide availability can change; check the museum’s current visitor information.

Miramar Palace

Miramar Palace stands between La Concha Bay and Ondarreta Beach. Built in an English-influenced style, it served as the summer residence of Queen Regent María Cristina and helped establish San Sebastián’s reputation as a royal seaside resort.

The city acquired the property in the early 1970s. Today it hosts educational and cultural activities, including events connected with the University of the Basque Country’s summer courses. The surrounding gardens form a public park with views towards La Concha and Santa Clara Island.

La Concha Beach

A walk beside La Concha Beach is one of the defining San Sebastián experiences. The beach stretches for roughly 1.35 kilometres, with a continuous promenade towards the Pico del Loro rocks, Ondarreta and Miramar Palace.

  • Services: toilets, showers, lifeguards and beach rentals are seasonal.
  • Swimming: conditions and lifeguard cover vary; follow the beach flags and local advice.
  • Look out for: Juan Rafael Alday’s white railings and the Belle Époque streetlights along the promenade.

At the eastern end of the bay, the former casino now houses City Hall, while the port begins just beyond it.

La Perla spa

La Perla began its modern life in 1912 as La Perla del Océano. The Belle Époque complex now operates as a thalassotherapy centre with spa circuits, treatments and food service. Sessions, prices and opening times are especially time-sensitive, so confirm them directly before booking.

San Sebastián port

Boats and waterfront buildings in San Sebastián port

San Sebastián’s compact triangular port sits between the Old Town, Monte Urgull and La Concha Bay. It combines fishing and leisure areas, while a walkway links the waterfront with routes onto Monte Urgull. The Aquarium is beside the harbour.

  • Boat trips: departures around the bay are seasonal and weather-dependent.
  • Working harbour: fishing activity varies by day and season, and the fish auction is not open to the public.
  • Best light: the late afternoon often gives a warm view across the boats and waterfront.

A short history of the port

Historic waterfront and boats in San Sebastián port

The modern shape of the port developed over several centuries, particularly from the 15th to the 19th century, when new harbour works increased its capacity. It remains an active waterfront managed by Basque and municipal authorities.

Frequently asked questions about San Sebastián

When is the best time to visit San Sebastián?

Late spring to early autumn generally offers the mildest conditions for beaches and long walks, but it is also the busiest period. May, June and September can offer a useful balance. The Tamborrada on 20 January is a major cultural occasion, while rain is possible in any season.

How many days do you need in San Sebastián?

Two full days cover the main sights at a steady pace; three days allow time for museums, Monte Igueldo, the beaches and a more relaxed pintxos route. Add longer if you want day trips along the Basque coast.

Where should you go for pintxos in San Sebastián?

The Old Town is the classic starting point, especially around 31 de Agosto, Calle Mayor and Pescadería. Try one or two specialities in each bar and move on, rather than ordering a full meal in the first place you enter.
