How to use Public transport in Prague
Mainly public transportation runs frequently during the day and night, just a single ticket is enough to travel on all trams, buses and the metro.
You can buy tickets at the metro machines, the news paper kiosk or at the Tabak stores. The tickets are available by time from 30 minutes, you can also get a 24 hrs, weekly and monthly ticket.
The time of transportation starts from the moment you stamp it. If you validate at 11:24 and your ticket is valid for 30 min, your time will end at 11:54. During this 30 min you can use the metro, trams or some buses (even combine them, no need to re-validate)
Be aware of the inspectors, they will check the tickets, to be safe VALIDATE your ticket in the yellow boxes. As you can see in the photo below, validate under the orange arrow. The fine for a non-validated ticket or not having one is up to 1000 CZK (30 EUR).
The taxis are one of the most common scams in Prague. Most of all don´t follow the law and they charge you what they want (including the taxis outside the airport). Maybe if you don´t have a lot of luggage you can use either the public transpotation sistem or you can use UBER.
