Public transport on the island is provided by an extensive network of buses and run by TITSA, who operate a fleet of modern, air-conditioned buses. TITSA buses cover most of the island and they are fairly frequent. For more than one journey, customers can purchase a TenMas contactless smart card for €2, which can be topped up with up to €100 travel credit. Using the TenMas card provides a discount over cash fares, and, for Tenerife residents, a card allowing unlimited travel for a montly fee is also available. The card can be purchased and topped up at bus stations and many newsagents. It is also valid on the tram in the capital, Santa Cruz (See Below).
