Which international bank cards work best at Sri Lankan ATMs?

Visa and Mastercard debit cards work reliably at almost every ATM across the country including remote areas like Jaffna, Trincomalee, and Arugam Bay. Revolut and Wise cards generally work well too offering excellent exchange rates without foreign transaction fees. Commercial Bank, Sampath Bank, Bank of Ceylon, and HNB have the widest ATM networks. Most ATMs charge a local fee of around four hundred rupees per withdrawal on top of any fees from your home bank.
