Money, Safety, Trains & eSIM in Spain
Spain's currency is the euro (€) — cards are widely accepted almost everywhere, including small tapas bars, so carrying large amounts of cash isn't necessary, though a little is handy for markets and tips. Spain is very safe overall; the main real risk is pickpocketing in crowded tourist areas, not violent crime. The AVE high-speed rail network connects major cities faster than flying door-to-door — Madrid to Barcelona or Seville both run under 3 hours. eSIM and local SIMs both work well for staying connected.
The unglamorous questions that actually shape your trip: how to pay for things without ATM fees eating your budget, what's genuinely risky versus just annoying, how to move between Spain's big cities efficiently, and how to get online the moment you land.
Money and ATMs
The euro (€) is used everywhere; cards — including contactless — are accepted at the vast majority of restaurants, shops, and even most small tapas bars, so Spain is easier to navigate cash-light than many destinations. When withdrawing from an ATM, always decline 'dynamic currency conversion' (being offered the amount in your home currency) — it carries a worse exchange rate than letting your own bank convert it. A card with no foreign-transaction fee saves real money over a two-week trip.
| Payment method | Where it works best |
|---|---|
| Card (contactless) | Nearly everywhere — restaurants, shops, transit, most tapas bars |
| Cash (euros) | Small markets, tips, some very traditional bars |
| Mobile pay (Apple Pay/Google Pay) | Widely accepted alongside contactless cards |
Is Spain safe?
Very safe by any international standard — violent crime against tourists is rare. The real, statistically common risk is pickpocketing and bag-snatching in crowded tourist zones: Barcelona's Ramblas, metro, and Barceloneta beach; Madrid's Puerta del Sol and metro; Seville's Santa Cruz quarter at peak times. Keep bags zipped and worn to the front in crowds, and don't leave phones or bags unattended on restaurant tables or beach towels.
Getting between cities: the AVE
Spain's AVE high-speed trains connect Madrid to Barcelona (around 2.5 hours), Seville (about 2.5 hours), and other major cities faster city-center-to-city-center than flying once you count airport transfer and security time. Book on Renfe's official site (or via Trainline) a few weeks ahead for the cheapest fares — prices rise noticeably closer to departure, similar to airline pricing. Seat reservations are included; just double-check your platform, since Spanish stations sometimes assign it only shortly before departure.
eSIM and staying connected
eSIM is the easiest option if your phone supports it — providers like Airalo and Holafly sell Spain or EU-wide data plans from around $5–20 for 7–15 days, activated before you land. A physical local SIM (Vodafone, Orange, or Movistar, sold at the airport or any phone shop) costs a similar range for two weeks of largely unlimited data and is just as easy to set up on arrival.
Overtourism and local etiquette
A handful of Spanish destinations — Barcelona especially, plus parts of the Balearic and Canary Islands — have seen visible anti-overtourism protests since 2024, driven mainly by local housing and rent pressure rather than hostility to individual travelers. Practically, this means: higher tourist taxes in some cities (Barcelona raised its overnight tax meaningfully in April 2026), occasional graffiti or banners in busy neighborhoods, and it's worth being a considerate guest — quieter in residential areas late at night, respectful of 'no photos' requests, and not treating short-term rental buildings as party venues.
