Euronet

The Euronet ATM on 25is Martiou in Thira (Fira) operates around the clock, every day of the week. If you need cash at any point during your stay on Santorini — whether you're paying for a taxi at midnight or picking up groceries before the banks open — this machine is accessible when most other financial services are not.

Euronet is one of Europe's largest independent ATM networks, with machines across Greece and the wider EU. Their ATMs accept most international debit and credit cards including Visa, Mastercard, and Maestro. Be aware that Euronet machines typically offer dynamic currency conversion (DCC) at the point of withdrawal, which means the screen may prompt you to confirm a conversion into your home currency. In almost every case, declining that offer and choosing to be charged in euros will result in a better exchange rate from your own bank.

The address — 25is Martiou 401 — places this ATM in the main commercial area of Thira, close to the bus terminal and the main road that connects Fira's town centre to the caldera-side streets. It's a practical stop if you're heading to or from the port or arranging transport around the island.

What to Expect

This is a standalone Euronet-branded ATM kiosk, not a full bank branch. There are no staff, no counter services, and no facility for exchanging foreign banknotes or traveller's cheques. The machine handles cash withdrawals in euros and provides a balance inquiry function. Transaction limits will depend on your home bank's daily withdrawal cap, which is worth checking before you travel.

Euronet machines are generally straightforward to use and offer on-screen instructions in multiple languages including English, German, French, and Russian — relevant given the diverse mix of visitors Santorini receives each season. The interface prompts you through each step clearly.

The location on 25is Martiou is a main arterial road through Thira, so the ATM is in a publicly visible, reasonably well-lit spot. That said, as with any ATM use, standard precautions apply: shield your PIN, be aware of your surroundings, and avoid carrying large amounts of cash unnecessarily once you've withdrawn.

The current Google rating of 1.4 from 10 reviews is low, which is not unusual for ATM listings — users often leave negative reviews after frustrating transaction experiences such as DCC prompts, declined cards, or out-of-service periods, rather than commenting on the ATM as a location. These issues are typically network- or card-related rather than specific to this machine.

How to Get There

The ATM is at 25is Martiou 401, Thira 847 00. This road runs through the commercial centre of Fira and is walkable from most accommodation in the town. From the main Fira bus terminal — the island's central transport hub — the address is within a short walk heading along 25is Martiou. If you're arriving by cable car from the old port (Skala), head uphill into town and look for the street signs for 25is Martiou.

Parking in central Fira is limited and congested during peak season, so reaching this ATM on foot is the most practical approach if you're already staying nearby. If you're driving from another part of the island, the main road through Fira passes along or near 25is Martiou.

Best Time to Visit

Because this ATM is open 24 hours a day, there is no wrong time to use it from an access standpoint. That said, the area around Fira's main commercial strip is busiest in the late morning through early evening during the high season (June to September), when cruise ship passengers and resort guests are both active in town. If you prefer a quieter transaction without a queue forming behind you, early morning or late evening visits tend to be calmer.

Santorini's high season runs from roughly April through October, and demand for ATMs spikes noticeably when large cruise ships dock at the island. On those days — which you can sometimes anticipate by the volume of coaches in town — ATM queues across Fira can form quickly. Carrying a small amount of cash as a backup during peak periods is a sensible habit.

Tips for Visiting

• Decline dynamic currency conversion. When the Euronet screen offers to charge your card in your home currency, always select the euro option. Your own bank's exchange rate will almost always be more favourable than the rate offered at the machine.
• Check your bank's foreign ATM fees before you travel. Many banks charge a flat fee per withdrawal plus a percentage. Withdrawing a larger single amount is usually more cost-effective than multiple small withdrawals.
• Know your daily limit. Your card's daily withdrawal ceiling is set by your home bank, not the ATM. If a withdrawal is declined, try a lower amount before assuming the machine is at fault.
• Have a backup card. It's worth travelling with two different payment cards in case one is blocked or declined by your bank's fraud detection system when used abroad.
• Notify your bank before travel. Many banks flag overseas transactions as suspicious. A quick call or in-app notification before departure reduces the chance of your card being frozen mid-trip.
• The nearest full bank branches are also located in Fira's town centre. If you need more complex financial services — such as currency exchange or a lost-card dispute — those branches are your best option during business hours.
• Keep your receipt. If you notice any discrepancy between the amount dispensed and the amount charged, the receipt and your bank statement together are what you'll need to raise a dispute.
