Best Family Activities in San Sebastián — Trip Planner

San Sebastián with kids, realistically

The bay does the childcare: La Concha is shallow, sheltered and lifeguarded, and Ondarreta at its western end is calmer still. Zurriola over in Gros has rips and suits teenagers rather than toddlers. The Aquarium and the Eureka science museum cover indoor hours. Monte Igueldo's century-old rides, including a water toboggan and a little mountain train, are aimed squarely at under-tens.

When the weather turns in San Sebastián

This coast is properly wet, near a hundred and fifty rainy days a year, and the city is built accordingly: the Parte Vieja's lanes are narrow enough to run a pintxo crawl half-sheltered. San Telmo, the Aquarium, Tabakalera and the Eureka museum are all indoors, and Tuesday's free San Telmo entry makes the cheapest wet afternoon. The Kursaal's glass cubes programme film and concerts.

What things cost in San Sebastián

San Telmo is ten euros, free on Tuesdays and free under twenty-five; the Aquarium around fourteen. A dbus single costs 1.95 euros and the night Búho fare 2.65. Pintxos run 2.50 to 4 each with a zurito of beer or a glass of txakoli near 2, so four bars and eight bites lands close to 30. The Igueldo funicular return is a few euros.

What to eat in San Sebastián

Pintxos are not tapas: you order them one at a time at the counter, and the hot ones come off the blackboard cooked to order rather than sitting under glass. The gilda, anchovy with guindilla pepper and olive on a stick, was invented at Casa Vallés. Ganbara does mushrooms, Txepetxa anchovies, Bar Néstor one tortilla at one o'clock, and La Viña baked the burnt cheesecake everybody now copies.

San Sebastián after dark

The evening is a txikiteo, one pintxo and one small drink per bar before moving on, worked outward through the Parte Vieja's grid from Calle 31 de Agosto. Txakoli gets poured from a height to raise its fizz. Bars run to about three, and Gros across the Urumea holds the younger, surfier crowd. Semana Grande in August puts an international fireworks contest over the bay nightly.

When to go to San Sebastián

The month to avoid is January — around 12°C (54°F) with roughly 14 rain days. Prices and crowds track the weather here: July is the sweet spot, January the month most people skip.
