Ten Travel Card
If you’ll be travelling a lot by public transport then it is worth investing in a plastic Ten+ Travel Card (www.titsa.com), which can be used on all bus routes (except on Teide and Teno lines) and offers 30% off the trip fare. The travel card costs €2, with top-ups from a minimum of €5 to a maximum of €100, available at bus stations, tram-station vending machines and some newspaper kiosks. Swipe your card when you board and swipe off as you disembark (if you don't swipe your card when you get off you will be charged for the entire route). The same card can be used by several users.
