From Gaudí to flamenco: a seasoned traveller’s autumn guide to Spain’s Barcelona–Seville route

Practical insights, vivid stops and smarter travel connectivity for your autumn Spanish journey

The first time I wandered down La Rambla in late October, it wasn’t the crowds or the street performers that stuck with me—it was the honeyed light catching the edges of Modernist facades, a gentle coolness in the air and the faint scent of roasted chestnuts. Spain in autumn is a different beast: quieter, golden, with the hint of mischief as Halloween nears and half-term brings families and solo adventurers alike.

Honestly, if you’ve ever tried navigating Spain’s train network with patchy mobile data (been there, done that), you’ll know how much smoother the journey feels when you’re always online. From finding hidden tapas bars in the Gothic Quarter to figuring out last-minute AVE train changes in Madrid, reliable connectivity is one travel essential I never compromise on anymore.

Must-visit stops: Barcelona, Zaragoza, Madrid, Córdoba, Seville
Getting around: High-speed AVE trains save time and are easy to book on the go

Why autumn transforms Spain’s Barcelona–Seville route

There’s something quietly electric about Spain in autumn. The crowds that fill Barcelona’s beaches in summer have vanished, replaced by locals wrapped in light jackets, sipping cortados in Plaça Reial. Trains run as frequently as ever, but you can actually find a seat by the window (my favourite way to see the landscape turn from coastal lushness to the ochres and reds of La Mancha). From experience, Madrid’s Retiro Park in late October bursts with colour—leaves crunching underfoot as joggers dart by. Meanwhile, Seville’s evenings cool just enough for you to actually enjoy an outdoor flamenco show. For families on half-term, it’s a godsend: fewer queues at the Sagrada Família, calmer plazas, and still enough daylight for impromptu ice-cream runs.

Why This Matters

Travelling in Spain during the autumn shoulder season means less time wasted queueing, lower accommodation prices, and more opportunities to connect with the real heartbeat of each city along your route.

Staying online in Spain: practical realities and eSIM know-how

Spain’s big cities—Barcelona, Madrid, Seville—boast excellent 4G and 5G coverage. Yet, I’ve found the signal can dip inside some thick-walled old town cafes or deep in the Madrid Metro. If you’re relying on data for Google Maps, digital tickets, or last-minute restaurant bookings (which, honestly, is most of us these days), having a plan B is essential. Traditional roaming charges are still a nasty surprise for many Brits and international visitors. Even in 2025, a few minutes on YouTube or a FaceTime call can rack up £10–£15 in charges with the wrong provider. That’s where eSIMs—a digital SIM you can activate before you even leave home—have changed the game. I first switched to an eSIM in Spain when my physical SIM got stuck in a dodgy rental phone; with instant activation on my iPhone, I was back online before my coffee cooled. Graba SIM’s Spain plans, for example, cover all the major networks (Movistar, Orange, Vodafone) and let you monitor usage in real time with their Data Pulse feature. For the perpetually forgetful (like yours truly), their home screen widget is a quiet lifesaver—no more guessing how much data you have left when streaming train times. Instant activation takes less than a minute, and—this is key—if something goes sideways, their live chat has been responsive even at 2am (Madrid time, anyway).

You can explore Spain eSIM plans or use the plan finder wizard to tailor your data based on your itinerary. Handy if you’re stringing together day trips—Zaragoza’s Basílica del Pilar makes a surprisingly charming Halloween background, by the way.

How to get started with eSIM in Spain (without the fuss)

Here’s my no-nonsense approach to getting connected before you hit the Spanish rails:

Check if your device supports eSIM

- Use Graba SIM’s compatibility checker. Most iPhones since XR and many Androids (like the Samsung S23) work perfectly.

Pick the right plan for your trip

- Estimate your data needs. For city-hopping with maps, bookings, and posting the odd photo? 3–5GB should last a week. For video calls or Netflix on trains, go higher.

Buy and activate in advance

- Purchase your plan online. You’ll get a QR code or link—scan it, and within about 30 seconds (on most devices), your eSIM profile appears.

Use Data Pulse and widgets

- Install Graba SIM’s lock screen widget so you can see your data balance at a glance. It’s one of those small things you only appreciate after you’ve been burned by surprise cutoffs.

Keep support contacts handy

- If anything feels buggy, use the 24/7 chat. Genuinely, I found their responses refreshingly human and quick.

Handy travel tips from Barcelona to Seville

Local Tips

In Barcelona, free Wi-Fi is everywhere but can crawl to a halt around Plaça de Catalunya during festivals or big matches.

Train stations (especially Madrid Atocha) have Wi-Fi, but the login process is fiddly and often asks for a Spanish phone number—skip the hassle with your own data.

If you’re heading to Córdoba for the day, book AVE tickets at least 48 hours ahead to avoid price spikes. The Renfe app sometimes glitches; mobile data helps you reload or use alternatives.

Halloween in Seville means costumed children parading through Santa Cruz in the early evening—worth catching if you’re around.

Battery drains faster on long AVE journeys, especially if you’re streaming. Pack a small power bank or use offline maps as backup.
