Turibús Circuito Turístico
Red double-decker buses run three circuitos (routes) across the city: Centro (downtown), Sur (south) and Basílica (north). Buses pass every hour or so and you can hop off and back on them at any designated stop. All routes stop on the west side of the cathedral. Fares are slightly higher on Saturdays and Sundays Turibús also offers themed tours, ie a cantina excursion.
