In Prague, parking on the streets outside of the paid car parks is a very complicated matter for both tourists and locals. On the streets in the city centre and in many residential areas, there are different parking zones reserved mainly for residents.
These zones are blue, orange, purple and green, each with slightly different conditions of use.
The parking in Prague is free on weekends in some districts.
The application https://www.easypark.com/en-cz will save you the time to determine which zone you are currently in and how much you have to pay. In addition, you will no longer have to look for a payment machine because you can pay directly from this application.
To avoid any troubles with parking in Prague, we strongly advise you to opt for safe and monitored parking.
