Mercado de San Martin on Calle Loiola in San Sebastian's Centro is the city's largest covered market, with two floors of fish, meat, vegetable and pastry.
Tip: Fish counters peak between 09:00 and 12:00; pair a market wander with a Sakona filter.
The Saturday outdoor producer stalls rotate through Donostia plazas (Plaza Easo, Plaza Berri, Calle San Francisco in Gros, Plaza Gaskuna), bringing Gipuzkoan.
Tip: Producer-direct Saturday only; the plaza changes weekly. The 3rd Saturday lands on Calle San Francisco in Gros.
