Although it's known as the Granada metro, this means of transport is more similar to what we know as a tramway or light railway, since only three of its 26 stops run underground. Its only line runs through the city from north to south and reaches nearby towns such as Armilla or Albolote.
The price of the regular ticket is € 1.35 (US$ 1.40) and € 2.70 (US$ 2.70) if you take the round-trip ticket.
You can also buy a one-day tourist card for € 4.50 (US$ 4.60), which will allow you to use the metro as many times as you want during the day.
The Granada metro operates from 6:30 am to 11 pm from Monday to Thursday, from 7:30 am to 11 pm on Sundays and holidays, and from 7 am to 2 am on Fridays and Saturdays.
The main disadvantage of the Granada metro or light railway is that it does not go through the historic center of the city and, therefore, does not reach most of its major monuments and attractions.
