It covers unlimited travel on all forms of public transport (city buses, trains and country coaches) for one day (which is considered to last until 8 am the next morning) throughout the country. It is not valid on sightseeing buses.
You can purchase a single ticket for 4.00 € [roughly £3.20], or a block of 5 such tickets for the cost of 4 single issue tickets: 16.00 € [± £13]. (or check Currency converter )
You may use the "Day-Pass" ticket in First Class accommodation (available on trains, but not on buses), by paying a supplement of 2.50 € [supplement payable in railway stations and on the trains themselves].
A "Weekend ticket" costing 6 Euro might be of interest to small groups. This type of ticket covers up to 5 people (who do not need to be family-related!) for unlimited travel on Luxembourg's public transport network for 1 day (either Saturday or Sunday) until 3 a.m. the next morning. Note that these tickets are not sold in blocks of 10, and that they are only valid in 2nd class
The airport is 6km from the city, the railway station in the centre.
The most economical way to get around in Luxembourg is by train and bus. Car rental rates in Luxembourg are among the lowest in Europe. A very economical way to travel Luxembourg and see its major attractions is to buy the Luxembourg Card. The Luxembourg Card, available from July 1 to October 31 each year, provides free access to the national public transportation network, free admission to 31 attractions, and discounts at three other attractions. Family or individual cards are available for a period of one, two, or three days. The price is very reasonable.
