Euronet

The Euronet ATM at 25is Martiou 401 in Thira is one of the more accessible cash machines on Santorini, operating around the clock every day of the week. Euronet is a widely recognized independent ATM operator across Europe, and this terminal accepts most international debit and credit cards. If you're heading out from the main town and need euros before a ferry, a restaurant meal, or a day trip, this is a straightforward stop.

Thira — also written Fira — is the island's capital and commercial hub, so having a 24-hour ATM in this part of town is genuinely useful. The address places it on 25is Martiou, one of the busier streets running through central Thira, within reasonable walking distance of the main square, the cable car area, and the caldera-facing hotels and restaurants.

Note that Euronet ATMs, like most independent (non-bank) ATMs in Greece, will typically offer a dynamic currency conversion prompt during the transaction. Choose to be charged in euros rather than your home currency to avoid unfavorable exchange rates applied by the machine rather than your own bank.

What to Expect

The machine itself is a standard Euronet terminal accepting Visa, Mastercard, Maestro, Cirrus, and most other internationally networked cards. Withdrawal limits vary by your home bank's daily cap, but the machine itself generally allows standard euro amounts in the range common across European ATMs.

Euronet charges a transaction fee, which will be disclosed on-screen before you confirm the withdrawal. This fee is separate from any charges your home bank may apply for international ATM use. If you hold a card from a bank that reimburses foreign ATM fees, the Euronet fee may still appear as a separate line item — check your card's terms before relying on reimbursement.

The ATM is located at street level and is accessible during all hours. Thira is well-lit and reasonably busy even at night, particularly in the summer season, so late-night withdrawals are not unusual. The surrounding street has shops, cafes, and accommodation, so the location is never truly isolated.

One practical note: with a Google rating of 1.4 from a small number of reviews, some users have reported issues that appear to be fee-related frustration or connectivity problems during peak season. These are common criticisms of independent ATMs across Greece and are not specific to this machine's reliability. That said, if you need cash for a significant amount, having a backup option — such as the Alpha Bank or Piraeus Bank branches also located in Thira — is sensible.

How to Get There

The ATM is on 25is Martiou street in central Thira, at coordinates 36.4200°N, 25.4319°E. From the main Fira square (Plateia Theotokopoulou), head roughly south along the main commercial street; 25is Martiou is within a short walk. If you're arriving from the cable car or the old port steps, walk up into town and you'll reach this part of the street in under ten minutes on foot.

Parking in central Thira is limited and congested in summer. If you're driving from elsewhere on the island, it's easier to park at one of the lots on the edge of town and walk. The street itself is not pedestrianized but is narrow, so driving directly to the ATM is impractical.

There is no specific bus stop at this address, but Thira is the central hub for the KTEL bus network on Santorini, and the main bus terminal is a short walk away on the road toward Kamari. From there, the walk to 25is Martiou takes around five to eight minutes.

Best Time to Visit

The ATM is open 24 hours, so timing is flexible. In practical terms, early morning — before 9:00 AM — tends to mean shorter queues if there are any, and you're less likely to encounter a machine that has run low on cash after a busy evening. Santorini draws very large tourist numbers from June through August, and ATMs in central Thira can see steady use throughout the day during peak season.

If you need cash ahead of a Sunday or public holiday, withdrawing the day before is a reasonable precaution. While this ATM operates continuously, some bank-linked ATMs on the island may have intermittent hours, so knowing where the 24-hour options are saves time.

During the quieter shoulder season — April, May, October — the machine is generally reliable and less congested.

Tips for Visiting

• Decline dynamic currency conversion. When the screen asks whether you want to be charged in your home currency or in euros, always select euros. The Euronet conversion rate is typically less favorable than your own bank's rate.
• Check your card's foreign ATM fee policy before you travel. Some travel-oriented cards waive foreign ATM fees; others charge a flat fee or a percentage. Knowing your card's terms helps you decide whether one larger withdrawal is better than several small ones.
• Bring a backup card. ATM connectivity issues are more common during peak season on Greek islands. Carrying a second card from a different network (e.g., one Visa and one Mastercard) reduces the risk of being stranded without cash.
• Note the fee upfront. Euronet will show you the transaction fee before you confirm. If the fee seems disproportionate to your withdrawal amount, consider withdrawing a larger sum in a single transaction rather than making multiple smaller ones.
• Bank ATMs are an alternative. Alpha Bank, Piraeus Bank, and National Bank of Greece all have branches and ATMs in Thira. Bank-owned machines sometimes have lower independent fees, though your own bank may still apply its own charges.
• Carry some cash for smaller vendors. Many smaller tavernas, local markets, and transport operators on Santorini prefer or require cash. Withdrawing on arrival rather than hunting for an ATM mid-trip makes logistics smoother.
• The machine is at street level and accessible at any hour, but if you're withdrawing a larger amount late at night, basic street awareness applies as it would anywhere.
