San Sebastián's main covered market in the Gros neighbourhood with excellent fresh fish, seasonal vegetables, and local cheeses.
Mercado de San Martín is the principal covered food market of San Sebastián (Donostia), occupying a dedicated market hall at Calle Urculu 8 in the Gros neighbourhood, just east of the Urumea river. The market has served the city's cooks — professional and domestic alike — since the mid-twentieth century, and its continued vitality reflects the extraordinary importance that Basque culture places on fresh, seasonal, locally sourced ingredients.
The stall mix is weighted heavily toward fresh fish and seafood, a reflection of the city's location on the Bay of Biscay. Counters display the morning's catch from nearby fishing ports: fresh anchovies (boquerones), gildas skewered with olive and pepper, sea bream, hake, and the kokotxas and txangurro that define Basque haute cuisine. The fish vendors know their product in minute detail and are accustomed to advising home cooks on preparation.
Beside the fish section, a row of vegetable and fruit vendors stocks produce sourced from smallholders across Gipuzkoa and the neighbouring Navarrese valleys. Seasonal variety is pronounced: late summer brings Gernika peppers and white beans; autumn brings wild mushrooms; winter showcases cabbages and root vegetables for the traditional puchero stew. A small dairy section offers Idiazabal sheep's milk cheese in varying stages of maturity, local cured chorizo, and farmhouse-style yoghurts.
Payment is accepted in cash and by card at most stalls, though card terminals are less universal here than at larger markets. There is no bargaining and no tourist-souvenir element; Mercado de San Martín is a working neighbourhood market where locals from the Gros, Amara, and Egia districts do their weekly provisioning. Tourists who venture beyond the Parte Vieja tend to find the atmosphere more relaxed and prices the same as or marginally lower than those in more central outlets.
The Gros neighbourhood is also celebrated for its pintxos bars, and several of those closest to the market incorporate the morning's produce directly into their menus by lunchtime. The combination of a market visit followed by a bar crawl through Calle Zabaleta and its adjacent streets constitutes one of the most authentic food experiences available in San Sebastián. The market closes firmly by 2:00 PM every day, and most stalls begin packing down from around 1:30 PM.

Frequently asked questions
Where is Mercado de San Martín in relation to the Parte Vieja?
It is a 15-minute walk east of the Parte Vieja (Old Town), across the Urumea river in the Gros neighbourhood. The route can easily be combined with visits to both areas in a single morning.
Is the market tourist-friendly or primarily for locals?
It is primarily a local market, but tourists are welcome. English is not widely spoken by vendors, though pointing and basic numbers work well. The absence of tourist staging is part of its appeal.
Does the market sell prepared food?
There is no dedicated prepared-food section or cafeteria within the market building, but the surrounding Gros streets offer abundant pintxos bars that open from mid-morning and serve fresh produce from the market.
What are the payment options at the stalls?
Most stalls accept cash; card acceptance is growing but not universal. Carrying €20–€30 in cash is advisable to cover stalls without card terminals.
