Metro station Barceloneta. Here you need to buy a ticket T10. It costs 7.60 euros and will accompany you all day. This travel card allows you to make up to 10 trips on various types of urban transport. Every time you enter the subway or bus, you need to attach a ticket to the electronic device and the trip will be written off. All trips that were made within an hour are considered as one trip. Thus, the electronic system itself recognizes how many trips to write off from the pass each time it is used. Your detailed itinerary takes into account the travel time of the metro and bus and, by and large, you can make up to 4 trips. But if you buy each ticket separately, it will cost 2.20 and time will be spent at each metro station or on the bus. Thus, a single ticket T10 is more profitable. It saves time and money. Another advantage is that if you want to walk longer in a particular place, you are not limited to only 4 trips and can safely exceed the number of trips to 10. Payment is made in the machines with a card or in cash.
