First Time in Lisbon: The Mistakes That Cost You a Day and a Lot of Small Change

Paying for every ride on board

This is the most common and most avoidable Lisbon mistake. Carris charges €2.30 for a bus ride bought on board, €3.30 for a tram and €6.20 for the Santa Justa lift. Buy a reusable Navegante Ocasional card for €0.50 at any Metro machine, load it with zapping credit, and the same tram or bus ride costs €1.72 on one card that also works on the Metro. Tapping a contactless bank card at a Metro gate is easier but not cheaper — €1.92 a journey — and a single loaded Carris/Metro title is €1.90.

• Navegante Ocasional card: €0.50, valid a year, reloadable at any Metro station.
• Zapping fare: €1.72 per Metro journey, and €1.72 for an hour across the Carris network.
• Riding more than four or five times in a day? The 24-hour Carris/Metro ticket at €7.25 wins — €10.35 with the Transtejo ferries, or €11.40 with the Sintra and Cascais trains.

Arriving on a Monday and heading straight to Belém

Portugal’s national monuments and museums generally take Monday as their closing day, and Belém is almost entirely national monuments — Jerónimos and Belém Tower included. A Monday in Belém leaves you with a riverside walk, a queue at the pastelaria and two locked doors. Check each site’s own page and move Belém to any other day; Mondays are better spent on the viewpoints, the ferry to Cacilhas, or the privately run sites that stay open.

Treating Sintra as a spontaneous afternoon

Sintra is forty minutes from Rossio station and genuinely worth a full day — but Pena Palace tickets are sold for a specific date and time, so turning up without one can mean the next available slot is hours away or gone. Book the slot first and plan the rest of the day around it. Park-only entry is €12 and the park-plus-palace visit is €20; the walk up from the town is steep, and the shuttle-bus queues in summer are long.

• Book Pena’s timed entry before you travel, ideally for the morning.
• Sintra plus Cascais in one day looks fine on a map and does not work in practice — choose one.

Wearing the wrong shoes on the wrong pavement

Lisbon’s calçada portuguesa — the hand-laid limestone mosaic underfoot almost everywhere — is beautiful, polished by a century of footfall, and treacherous the moment it rains. Combine that with a city of steep lanes and stairs and smooth-soled shoes become a genuine hazard rather than a style choice. Bring grip. It is the single most practical thing on this list.

Planning your climbs around funiculars that are not running

Half the Lisbon guidance written before this year assumes you can ride the Glória up to Bairro Alto or the Bica down to Cais do Sodré for the price of a ticket. Carris currently lists the Glória, Bica and Lavra ascensores as closed or suspended, and points passengers to ordinary bus routes instead — the 51E in place of the Glória, the 22B in place of the Bica. If you have been picking a hotel or a walking route on the assumption that a funicular will do the hard metres for you, check carris.pt against your own dates and plan a bus, a taxi or the stairs instead.

• Glória → take the 51E; Bica → take the 22B; both climbs are otherwise on foot.
• The Santa Justa lift is a separate vertical lift, not one of the funiculars — but at €6.20 on board for up to two journeys, the free walk up through Chiado to the Carmo terrace reaches the same height.

Queuing for tram 28 at Martim Moniz

Tram 28 is a working tram line that happens to run a spectacular route, and the queue at its Martim Moniz terminus can eat an hour before you board a carriage packed tight enough to be a pickpocket’s favourite address in Portugal. Board mid-route instead, go early or late in the day, keep your bag in front of you — or ride tram 12E on its shorter loop, or simply walk the Graça-to-Alfama descent, which is the best part of the route anyway.

Assuming Lisbon is still cheap Europe

Transport, coffee and a pastel de nata remain genuinely inexpensive. Central lodging is not: short-term rental registrations are capped in the historic parishes, hotel supply in the old city is constrained by the buildings themselves, and the two annual spikes — the Santo António nights of 12–13 June and Web Summit week in November — reprice the whole city. Budget the room like a Western European capital and the rest like Portugal.

Trying to day-trip Porto

Porto is a beautiful, entirely different city and it is around three hours away each way on the fast train. Squeezing it into one day from Lisbon means six hours of rail for a few hours of Porto. Give it two nights of its own. For a real day out of Lisbon, the realistic options are Sintra, Cascais and Estoril on the coastal line, or Setúbal and Arrábida across the bridge.
