How to use public transport in a new city and not get lost

November 8, 2026 · 4 min read

Public transport is often the best way to see a city. It is cheap, it takes you where residents go and it avoids the stress of driving and parking. It can also be confusing in the first hour: different lines, different tickets, different rules about validating and no obvious place to ask.

Most systems follow the same logic, and a little preparation makes a new one easy to read.

Work out the system first

Spend ten minutes before you arrive, or on your first evening, answering a few questions.

What modes exist? Metro, tram, bus, suburban rail, ferry, funicular, cable car. Some cities have all of them; some are mainly buses.
Is it one system or several? In many cities, one authority runs everything, and one ticket works on all of it. In others, each mode has its own operator and ticket.
Which parts do you need? For most visits, two or three lines cover everything you want. Learn those, not the whole map.
When does it run? Check the first and last service, especially at weekends and for night routes.

The city's own transport website or app is the best source, and the one that is up to date.

Paying for it

Ways to pay vary a lot, so check this before you try. Common systems include:

Single tickets bought from a machine, a kiosk, a driver or an app.
Day or multi-day passes, which are worth it if you plan several trips a day.
Rechargeable cards, which you load with money or a pass and tap in and out. Some cities charge a small deposit for the card.
Contactless payment with a bank card or phone, tapping at the gate or on the bus. This is now common in many cities, but not everywhere.

Whichever you use, a few rules help:

Look at what the ticket machine offers in a language you can read, and check for an English option.
If you have to validate a paper ticket, do it every time, because inspectors check, and an unvalidated ticket may count as no ticket.
Keep the ticket until you leave the station, since some systems check at exit.
Do not buy from strangers who offer to help at the machine.
For a group, check whether there is a group or family ticket, and whether it works out better than separate tickets. Prices and rules change, so look at the transport authority's site, not a blog post.

Reading the map

Metro and tram maps show connections, not distances, so they can be misleading when you want to know how far something is. Use them to work out which line you need and where to change. Then use a map app to see how far you will walk at each end.

How to read a route:

Find your start and end stations on the map.
Note the line colour or number and the direction, which is usually named by the last stop on the line, not where you are going.
Note where you change, and how far apart the platforms are.
Count the stops, so you know when to get off.

Apps such as the city's own and general map apps can give you a route with times and platforms. They need a connection, though, so download the offline map and take a screenshot of the route if you are unsure of the signal underground. Travel offline explains how to prepare.

Manners and mistakes

Every city has its own habits, and watching for a minute is the best guide. Some common ones:

On escalators, people often stand on one side and walk on the other.
Let people off before you get on.
Give up priority seats to people who need them.
Keep bags in front of you or on your lap in crowds.
At rush hour, trains and buses are full. If you have luggage, travel at another time.
Buses may require you to signal a stop, or to board only at the front.

Common mistakes include taking the right line in the wrong direction, tapping in without a valid ticket, or leaving a pass in a pocket you do not check.

Staying safe

Public transport is safe in most places, but crowded places attract pickpockets in any city. Keep your phone and wallet in a front pocket or a zipped bag, and be a little more careful at busy stations and on packed trains. If you travel late at night, choose well-lit stops and busy carriages. For more, see travel safety tips.

Plan your day around it

Having a plan beats working it out as you go. When you plan each day, group places that are on the same line or in the same area, so you are not crossing the city three times. Note which station is nearest to each place, and how you get from one to the next.

Cities like Lisbon, with its trams and hills, reward a plan that follows the lines.

Before you set off

Write down three things before you leave your accommodation: the line you take, the direction and where you get off. Check the last service back if you will be out late. After one or two journeys, the system starts to make sense, and the city gets much smaller.
