The currency in Tenerife is the euro. You can buy euros from your local Thomas Cook store before you go on holiday. Alternatively, you can order your Tenerife currency online or even get a Cash Passport, which is a prepaid travel card. These are the best ways in order to get the best conversion rate. It’s possible to exchange your money when you are in resort too, but avoid getting your travel money at the airport as this can be a lot more expensive.
