At the heart of San Sebastián, the Bay of La Concha forms a sheltered curve between Mount Urgull and Mount Igueldo, with Santa Clara Island in the middle. The bay brings together two urban beaches, a long seafront promenade and landmarks that are easy to explore on foot. Tides change the amount of sand available on the shore; on Santa Clara, the small beach can appear or disappear with the water level. Check local conditions before planning a swim or a crossing to the island.
The Bay of La Concha is one of San Sebastián’s iconic places. See the complete guide to the city’s iconic spots.
For a first walk, start near City Hall and Alderdi Eder Gardens, then follow the La Concha promenade past the beach towards Miramar Palace. The route continues to Pico del Loro and Ondarreta, roughly 1.5 kilometres from City Hall. You can enjoy the view from the pavement or descend to the sand when the tide leaves enough room. From Ondarreta, continue to Eduardo Chillida’s Wind Comb, or return towards the city centre through the Antiguo neighbourhood.
History and Origin of the Bay
The bay and beach take their name from their shell-like shape when seen from above. La Concha became a fashionable seaside resort in the nineteenth century. In 1845, doctors recommended sea bathing in San Sebastián to Queen Isabella II; the court and aristocracy later followed the new custom. Summer visitors helped turn the city into a celebrated resort, and parts of the seafront still reflect that period.
The seafront preserves visible reminders of this bathing history. La Perla, built in 1912 as a bathing establishment and now a thalassotherapy centre, stands along the promenade. The ornamental railing designed by municipal architect Juan Rafael Alday has become one of the city’s best-known landmarks. Walking beside the bay brings together this architectural heritage, a working urban beach and views towards Miramar Palace and Santa Clara Island.
The bay is also a useful way to understand the city’s layout. From the centre, the promenade leads towards Miramar Palace and its gardens, then on to Ondarreta and the Wind Comb. In the opposite direction, the Old Town, harbour and Mount Urgull offer different viewpoints over the same curve of coastline. Beach, neighbourhoods and walking routes sit close together here, so La Concha is part of everyday local life as well as a visitor itinerary.
A practical way to see the bay is to walk from City Hall towards Ondarreta, stopping at La Perla or the Miramar gardens along the way. The route can be done in stages and does not require a car. If you plan to spend time on the sand, check the tide: the usable beach area changes noticeably through the day.
The Beaches of the Bay
The bay is home to three beaches, each a true treasure:
- La Concha Beach: the central beach stretches for about 1.5 kilometres, from City Hall to Pico del Loro. The seafront promenade provides easy access to the sand, including at the Clock area, one of the main entrances. The water is shallow, but the tide can greatly reduce the width of the beach. Check conditions if you plan to swim or spend several hours on the sand. The promenade also leads past La Perla towards Miramar Palace and Ondarreta.
- Ondarreta Beach: at the western end of the bay, it continues the La Concha promenade towards the Antiguo neighbourhood. Miramar Palace gardens sit above the shore; follow the seafront west to reach Eduardo Chillida’s Wind Comb. The waves are generally moderate, but sea conditions vary, so check the beach information before swimming. This stretch is a good choice for combining a beach visit with a longer walk along the coast.
- Santa Clara Island Beach: this small shore in the middle of the bay depends on the tide and can almost disappear as the water rises. In the boating season, visitors can reach the island by shuttle from the harbour; swimming is another option, but distance, currents and sea conditions must be taken seriously. The island has a bar terrace and seasonal services in summer. You can also visit Cristina Iglesias’s Hondalea, installed in the former lighthouse keeper’s house; check access arrangements and opening times before setting out.
Santa Clara Island: The Treasure of the Bay
Santa Clara can be explored on foot via its paths and steps, which lead to viewpoints and the lighthouse. In summer, shuttle boats connect the island with the harbour, although departures and swimming depend on the season and sea conditions. Its small sandy area is not always visible because it changes with the tide. Check boat times and Hondalea access details locally before travelling, and see our Santa Clara Island guide for more about the visit.
The La Concha Promenade
The promenade follows the bay from City Hall towards Ondarreta. Its ornamental railing and street lamps make the route easy to recognise; the lamps also serve as trophies at the San Sebastián International Film Festival. The Clock area is one of the main entrances to the beach. Further west, La Perla—built in 1912—and the gardens of Miramar Palace mark useful stopping points. Continue to the Wind Comb or turn back towards the centre. The walk from City Hall to Pico del Loro is about 1.5 kilometres, not counting detours or stops.
Activities and Events in the Bay
- La Concha Regattas: held in September, these traineras rowing races are a major event in the Basque coastal calendar. Spectators follow the crews from the bay and viewpoints along the shore. See our current regatta guide for that year’s schedule and results, which change annually.
- Aste Nagusia (Semana Grande): San Sebastián’s main summer festival takes place in August. The programme varies each year and includes cultural activities and the city’s international fireworks competition. Check the current year’s dates and programme before planning your visit.
- Water activities: kayaking, stand-up paddleboarding and sailing offer a view of the bay from the water. Rentals and guided outings depend on the season, weather and sea conditions; check availability with the provider before booking. Even in calm weather, follow local instructions and keep clear of bathing areas.
Gastronomy and Exceptional Views
The promenade offers places to pause around La Perla, City Hall and the Antiguo neighbourhood. For pintxos, continue inland towards the city centre and the Old Town, both a short walk from the waterfront. This makes it easy to combine the beach and seafront with a neighbourhood visit and a meal. Terrace hours and beach services vary through the year, so check current opening times rather than relying on a summer schedule.
Conservation and Sustainability
Before choosing a beach, check the tide: the sand at La Concha narrows at high water, while Santa Clara’s small beach depends on the water level. Follow beach flags and swimming instructions, especially if you are considering the swim to the island. Lifeguards, boat shuttles and some beach services operate seasonally; confirm their schedules on the day of your visit. Wear suitable shoes for Santa Clara’s paths and check Hondalea’s access information before setting out.
Landmarks and curiosities
A few landmarks help make sense of the view: the Clock area is one of the main beach entrances; the promenade’s street lamps are used as trophies at the International Film Festival; and Miramar Palace marks the transition between La Concha and Ondarreta. From Santa Clara, the perspective reverses, with the city and both hills framing the bay. At low tide, the island’s small sandy shore appears; at high tide it may nearly disappear.
La Concha is easy to explore on foot, from the promenade and beaches to Santa Clara Island. For practical details, see our guides to La Concha Beach, Ondarreta and Santa Clara Island. Before you go, check the tide and current information on boat services and beach facilities.
