ATMs are accessible in large cities like Havana or smaller cities with a large amount of tourists like Viñales, but are rare/non-existent in other parts of Cuba. Please note that you won’t be able to use cards that are linked to US banking institutions. Ensure you have other payment options available in case you can’t access an ATM while traveling in Cuba. The ATM restrictions are another great reason to budget properly and bring the proper amount of cash.
