If you’re looking for a European destination that ticks all the boxes for a family holiday – beautiful beaches, fun attractions, and incredible food – then San Sebastián with kids should be right at the top of your list.
We visited during Easter 2026 with our kids (aged 10 and 8), and honestly, it was one of those rare trips where everyone was happy – from morning beach runs to evening ice creams along the promenade. If you’re planning family travel in Spain, this guide covers the best things to do in San Sebastián with kids.
🌊 La Concha Beach: The Best Beach in San Sebastián for Kids
When it comes to San Sebastián with kids, La Concha Beach is hard to beat.
The beach is set in a sheltered bay, meaning the water is calm and ideal for paddling, swimming, or even trying a bit of bodyboarding. The soft golden sand makes it easy for kids to play for hours, and there’s loads of space even during busy periods like Easter holidays.
There are also clean toilets, showers, and plenty of places nearby to grab snacks or drinks (a huge win when travelling with kids). We found ourselves coming back here every single day.
🎡 Monte Igueldo: A Must-Do in San Sebastián with Kids
One of the most fun things to do in San Sebastián with kids is a trip up to Monte Igueldo.
You can either drive or take the charming funicular railway to the top – which is already an adventure in itself. Once you’re up there, you’ll find a small vintage amusement park that feels like stepping back in time.
Think:
- Retro rides
- Simple rollercoasters
- Bumper cars
- Incredible panoramic views over the bay
It’s not a massive theme park, but that’s actually part of its charm. It’s manageable, affordable, and perfect for younger kids.
🐠 San Sebastián Aquarium: Perfect for Kids (and Rainy Days)
If the weather turns (or you just fancy a break from the sun), the San Sebastián Aquarium is a brilliant option.
Located right by the harbour, it’s engaging without being exhausting – ideal when travelling in San Sebastián with kids.
Highlights include:
- A glass tunnel where sharks and rays swim overhead
- Interactive exhibits
- Local marine life displays
It’s just the right size to keep kids entertained for a couple of hours without it turning into a full-day commitment.
🍽️ Eating Out in San Sebastián with Kids
One thing that really surprised us about San Sebastián with kids was how easy it is when it comes to food.
While it’s famous for high-end cuisine, there are loads of relaxed pintxo bars where kids can try little bites – or just stick to bread, chips, and croquettes if they’re feeling less adventurous.
If you’re looking for more ideas to keep everyone entertained back at your accommodation, I’ve also shared some family game ideas that actually work – perfect for winding down after a busy day exploring.
And of course… ice cream stops are non-negotiable. The promenade along La Concha is perfect for an evening stroll with something sweet in hand.
🚶♀️ Why San Sebastián is Perfect for Family Travel in Spain
What really makes San Sebastián with kids such a great choice is how easy it is:
- Everything is within walking distance
- The promenade is buggy-friendly
- It feels safe and relaxed
- There’s a great mix of beach, activities, and food
You don’t need to over-plan – just wander, eat, explore, and repeat.
Final Thoughts: Is San Sebastián Good for Kids?
Absolutely. If you’re considering family travel in Spain, San Sebastián is one of the best choices.
Between La Concha Beach, the vintage fun of Monte Igueldo, and the aquarium, there’s more than enough to keep kids entertained – without it feeling like a “kid-only” holiday.
It’s one of those rare places where adults get incredible food and scenery, and kids get freedom, fun, and ice cream. Everyone wins.
