Give San Sebastián, also called Donostia, two full days: the Old Town and La Concha, then one chosen Urgull, Aquarium or slower neighbourhood plan. Keep hill walking optional and exposed seafront paths weather-dependent. You do not need to collect every beach, hill and paid attraction to have a complete city visit.
Two days: old town and bay, then one chosen interest
- Day 1: Old Town lanes, Plaza de la Constitución, the port area and a chosen La Concha promenade section, with an actual meal break.
- Day 2: a manageable Urgull walk in suitable conditions, or a separately ticketed Aquarium visit, with time for a shorter city or Urumea riverside section.
Arrival/departure are extra. No hotel, transport, guide, hill access, boat trip, Aquarium ticket or meal is booked or included. € means euros, not INR; hours are local. This is not an aviation, train, visa or medical-rule guide, and a seaside itinerary is not a swimming-safety assessment.
The official tourism itinerary connects the Old Town, port, bay and hill choices. We spread those ideas over two days and leave alternatives rather than copying its one-day route as a compulsory pace. Bilbao is a separate onward-city plan, not an extra block that must fit here.
Day 1: Old Town, port and a shorter La Concha section
Use Plaza de la Constitución and the Old Town as the main first-day area. Choose lanes, a cafe break and the port before a manageable section of the La Concha promenade. An attractive walking route is not a promise that every museum, church or bar interior is open.
The tourism office's walking page also offers the Urumea river and Cristina Enea Park as distinct route ideas. Use them as alternatives when a quieter or shorter day suits, not more compulsory stops after the whole bay. Decide how far to go based on the group, conditions and time for returning.
Pintxos are part of the city experience, but a vegetable garnish is not an ingredient list. Ask about fillings, sauces, eggs, dairy, fish/meat stock and shared preparation before assuming vegetarian, vegan or Jain suitability. The Indian restaurant below is a separately checked menu option rather than a guarantee about every bar.
Urgull: seasonal gates are not a universal easy walk
Monte Urgull has uphill paths and several starting points, including near Santa María, San Telmo/Zuloaga and Paseo Nuevo. The tourism page describes tarmac routes and viewpoints; that does not mean the climb is flat, suitable for every wheelchair or effortless in wet conditions.
Official access hours are 1 May-30 September 08:00-21:00 and 1 October-30 April 08:00-19:30; access is closed at night. These are hill-gate hours, not proof that the Casa de la Historia, library or every facility is open for the same period.
Keep the hill optional rather than promising both Urgull and another summit. If you want a building interior, check its own current programme. If the climb does not fit your group, a shorter lower-city section is a valid replacement, not a failed itinerary.
Paseo Nuevo is not an all-weather route. The tourism office explicitly says it is usually closed when weather becomes too bad. Do not turn dramatic wave photographs into an instruction to approach the breakwater, walk past a barrier or make the full loop regardless of conditions. Follow actual local closures and choose an inland alternative. This article does not establish that any particular viewpoint is safe during a storm.
Aquarium: admission still involves the ticket office
The Aquarium is at Plaza Carlos Blasco Imaz 1, by the port. It is an alternative to hill walking or a chosen main visit, not merely a stop to add after every outdoor route.
For October-March, tourism sources list Tuesday-Friday 10:00-19:00, weekends/public holidays 10:00-20:00 and Monday closed except stated holiday/long-weekend exceptions. Other seasonal periods have different schedules. The tourism shop also lists 25 December, 1 January and 20 January as exceptions, so confirm the actual holiday date directly instead of assuming normal hours.
The ticket office closes one hour before site closing. The operator's own shop and tourism shop both say online purchase does not avoid the ticket-office queue or validation. Do not describe these products as guaranteed skip-the-line admission. Allow time for entry and the visit, not a closing-time rush.
Two Aquarium sales channels, different terms
The Aquarium's own shop displays an adult €16 product valid for one month from purchase, for a single entry. It requires presenting the QR ticket at the ticket office, says no refunds or ticket changes, and directs reduced-rate categories to buy at the counter with relevant proof.
The tourism shop separately displays adults €16, children 4-12 €8 and ages 0-3 free, but says its ticket is valid only on the selected calendar date. It also has separate cancellation wording saying no cancellation less than 48 hours before service and refers to its contract terms. That is not a blanket refund right and is not the operator shop's one-month/no-change product.
The pages also disagree on paperwork for under-4s: the operator shop says they also need a ticket; the tourism shop says no ticket required. Do not tell a family simply to arrive without one. Confirm the chosen channel's process with the Aquarium before purchase or arrival. Keep validity, refunds, child documentation and reductions tied to the product actually being bought, rather than combining the most generous line from each page.
The tourism accessibility page describes stairs, a ramp and a platform lift at the entrance, noting the ramp is steep, over 8%. Inside it lists lifts and an alternative platform/main-lift route where part of the tour uses stairs. Ask staff about the actual entrance and route you need; "accessible" does not mean every path has no slope or no assistance requirement. Some touchable replicas need advance arrangements. The operator's shop prohibits food/drink inside, so plan a separate meal.
Indian food: Taj Mahal's vegetarian section needs reading
Taj Mahal's own site gives Río Deba 2, local A, Donostia/San Sebastián 20012. Do not replace that with a similarly named restaurant or assume it is beside whichever beach you are visiting.
The site has separate delivery and collection tables, including different Tuesday lunch availability and some later collection endings. These are ordering-channel hours, not verified dine-in kitchen or table availability. Ask directly for the service you need. It also labels some offers delivery only and some menus in the restaurant only; an amount in one section is not automatically a final bill in another.
Its vegetarian section describes mushroom and aubergine dishes, Aloo Goobi with cauliflower/potato, and Vegetable Balti with vegetables in sauce. These short descriptions do not list every cooking fat, base or side. Ask about rice, bread, sauces, stock, butter, cream and shared utensils.
Palak Paneer is explicitly spinach, cream and cheese; Tarda Dal is lentils with a strong garlic sauce. Thus vegetarian does not mean vegan, and a lentil dish is not automatically no-garlic or Jain. A mixed "Vegetable Samosa + Chicken Curry + Keema Naan" set is not vegetarian because the first item is vegetable. Confirm the complete order and allergies, not only the first familiar dish name.
With only one full day, keep the Old Town and a chosen bay section, or one major paid visit with a shorter city block. Browse other travel guides for a separate onward-city plan.
Source check: 15 November 2026. Eight primary tourism, attraction and restaurant sources were read. Recheck actual weather closures, hill/facility hours, selected ticket product, under-4 paperwork, accessible route and meal requirements.
