Home to the nation’s capital and biggest city of Warsaw, Central Poland is the entry point for most travelers who arrive in the country by air. Industrial Lodz, the second biggest city, is here too, almost exactly at the country’s middle. Poznan and Torun are also popular with tourists, each boasting very pretty Old Town areas. Kampinos National Park, Poland’s second-largest, covers about 150 square miles. It's within easy reach of Warsaw and is a great site for hiking, cycling and skiing.
