As with the rest of Ibiza and Spain, the currency in San Antonio Bay is the Euro. It’s an incredibly popular holiday destination, so you’ll find that both ATM machines and foreign exchange facilities are easy to come by. However, for ease and in order to get the best rate, we recommend that you buy your travel money before you leave the UK. You can order Euros online via ThomasCook.com or pop in to your nearest branch to get them.
