For Lisbon city transportation, you have 6 different main options and 1 transportation card to use these options. You can easily reach any point you want to go by using these transportation options and the card.
Although Portugal is a small country, moving around is not the easiest. We have many options: buses, trains, barges/ferries, trams and of course cars (own, rented or shared). I will try to bring the subject closer to the interested.
Trams, buses, metros, ferries, taxis, Uber or Taxify, and walking are all options for getting around Lisbon. There's also a government-run bike-sharing program, albeit it's not the most well-thought-out or functional.
If you are in Lisbon it’s really hard not to notice and talk about the Electronic Scooters. They are one of the most favourite and enjoyable transportation vehicles in Lisbon.
