You can download a bus route map and timetable from www.titsa.com (the site is in English).
Tenerife offers both urban and inter-urban bus lines, making it easy for travellers to get from one place to another on the island, whether they are trying to get across one town or between several areas. The TITSA website offers a convenient mapping system which allows visitors to see which buses to take and to check route schedules.
The Bonovia (formerly BonoBus) discount ticket (€15 or €30)
allows heavily discounted fares. Purchase from bus stations, bookshops or other outlets carrying the green circle logo; simply tell the driver the destination and put the ticket in a machine which deducts the fare from the initial payment; put it in the machine twice for two people etc; when it runs out, pay the difference in cash to the driver; it also allows free or very cheap connections if you use another bus within two hours of the first; it also gives discounts at some museums.
The Bonovia ticket is available at the South airport from the last shop at the departures end - La Alpizpa opposite gate 47 and the Information Desk. U-Turn left when leaving Arrivals - it's 2 minutes walk from arrivals to the shop and 2 minutes back to the bus stops! The shop is open 1000-1800 - but not on public holidays.
