Getting there 

Although Lublin is the biggest city in Eastern Poland, its proximity to Warsaw always made it feel that an airport is not needed. You can get there by rail or by road. 

Trains

Lublin is a major railway hub, with direct connections to most bigger citities in Poland and a handful of Ukrainian ones. There are several connections every day to and from Warsaw Central (Warszawa Centralna) station in a 2-3 hours tact (the journey takes 2h20 on a "fast" train), 2 trains a day to Cracow (4h30), Katowice (5h) and Wroclaw (8h), one to Bydgoszcz (5h30), Poznan (6h), Szczecin (9h) and Gdansk (6h). The train station is situated approximately 2 km from the Old Town. To get there, you can take buses #1 (3 stops) or  #13 (3 stops) departing from bus stops located in the Western part of the Station Square.
See www.pkp.pl for trains timetable.

You can also book a train to Lublin online, unfortunately - since most of the trains are without seat reservations - it's currently possible to book only one train online.

Buses 

The main bus terminal (Główny Dworzec Autobusowy) is located just across the street from the Castle of Lublin and services almost all cities in Poland. Apart from regular buses, you can choose a faster "minibus" option. The "minibus" stop in Warsaw is located on the Jana Pawla street, outside of the Holiday Inn hotel.

Getting around

Most of the tourist attractions in Lublin are located in and around the Old Town, along the streets Grodzka - Bramowa - Krakowskie Przedmieście. The Concentration Camp Museum of Majdanek, the Open Air Rural Museum in Sławinek and the Botanical Garden are located on the outskirts, within a 20 mins bus ride from the Old Town. 

A local flavour is introduced to the public transport system by trolleybuses, operated by the municipal carrier MPK. In trolleybuses and buses operated by MPK you should use tickets which can be purchased at kiosks and newsagents' throughout the city. A single ticket costs 1.80 PLN, you must also have one 2 PLN ticket per every piece of luggage, whose sum of dimensions exceed 120 cm. You need to validate the tickets on the bus already in the stamping machine.

At ul. Przystankowa 1, not far from the gate to the old town Brama Krakowska you can buy weekly tickets (29 PLN). 

Private carriers constitute about 50% of the buses used in the city. They are listed in timetables and operate under a concession system. Contrary to the municipality buses, you don't need to buy any tickets, you simply pay the driver or the ticket officer on the bus. The fare price is listed on the bus and it's usually less than the one by MPK.
