You can also drive, ride, pedal or walk into Portugal, with major border posts open around the clock. Getting Around Flights inside Portugal are expensive and hardly worth considering, given the short distances involved. Trains are much cheaper, but it's almost always quicker to go by bus - especially as a number of private companies operate express services between major cities and the Algarve. There are dozens of car-rental agencies in Portugal, though you should bear in mind that petrol is pricey. Bicycles can also be rented in some tourist areas.
Local transport includes trams, buses and plentiful and cheap taxis.
