1. Take Advantage of Luxembourg's Free Public Transportation
Everyone in Luxembourg benefits from free public transport. You can use buses, trams, trains moving in the city and even the funicular for free. Just get on and go! The only time people are required to buy a ticket is when they want to travel by first-class on train.
Moreover, if you are going to other countries, you have to bear the cost of that part too. There is no need to have a ticket to use public transport but you may be asked to produce your identification details.
Pets and luggage are also allowed free of charge. You can plan your trip using the Mobiliteit app. It is simple and thus an excellent opportunity to take a tour around the country of Luxembourg.
