Poland’s territory extends across several geographical regions. In the northwest is the Baltic seacoast, which extends from the Bay of Pomerania to the Gulf of Gdansk. This coast is marked by several spits, coastal lakes (former bays that have been cut off from the sea), and dunes. The largely straight coastline is indented by the Szczecin Lagoon, the Bay of Puck, and the Vistula Lagoon. The center and parts of the north lie within the North European Plain. Rising gently above these lowlands is a geographical region comprising the four hilly districts of moraines and moraine-dammed lakes formed during and after the Pleistocene ice age. These lake districts are the Pomeranian Lake District, the Greater Polish Lake District, the Kashubian Lake District, and the Masurian Lake District. The Masurian Lake District is the largest of the four and covers much of northeastern Poland. The lake districts form part of the Baltic Ridge, a series of moraine belts along the southern shore of the Baltic Sea. South of the Northern European Lowlands lie the regions of Silesia and Mazovia, which are marked by broad ice-age river valleys. Farther south lies the Polish mountain region, including the Sudetes, the Cracow-Częstochowa Upland, the Świętokrzyskie Mountains, and the Carpathian Mountains, including the Beskids. The highest part of the Carpathians is the Tatra Mountains, along Poland’s southern border.

The Polish Baltic coast is approximately 528 kilometres (328 miles) long and extends from Świnoujście on the islands of Usedom and Wolin in the west to Krynica Morska on the Vistula Spit in the east. For the most part, Poland has a smooth coastline, which has been shaped by the continual movement of sand by currents and winds from west to east. This continual erosion and deposition has formed cliffs, dunes, and spits, many of which have migrated landwards to close off former lagoons, such as Łebsko Lake in Słowiński National Park. The largest spits are Hel Peninsula and the Vistula Spit. The largest Polish Baltic island is Wolin. The largest port cities are Gdynia, Gdańsk, Szczecin, and Świnoujście. The main coastal resorts are Sopot, Międzyzdroje, Kołobrzeg, Łeba, Władysławowo, and the Hel Peninsula.

With almost 10,000 closed bodies of water covering more than one hectare (2.47 acres) each, Poland has one of the highest numbers of lakes in the world. In Europe, only Finland has a greater density of lakes. The largest lakes, covering more than 100 square kilometers (38.6 square miles), are Lake Śniardwy and Lake Mamry in Masuria, as well as Lake Łebsko and Lake Drawsko in Pomerania. In addition to the lake districts in the north (in Masuria, Pomerania, Kashubia, Lubuskie, and Greater Poland), there is also a large number of mountain lakes in the Tatras, of which the Morskie Oko is the largest in area. The lake with the greatest depth - of more than 100 metres (328 ft) - is Lake Hańcza in the Wigry Lake District, east of Masuria in Podlaskie Voivideship.

has 21 mountains over 2,000 metres (6,561 ft) in elevation, all in the High Tatras. The Polish Tatras, which consist of the High Tatras and the Western Tatras, is the highest mountain group of Poland and of the entire Carpathian range. In the High Tatras lies Poland’s highest point, the northwestern peak of Rysy, 2,499 metres (8,199 ft) in elevation. At its foot lies the mountain lake, the Morskie Oko. The second-highest mountain group in Poland is the Beskids, whose highest peak is Babia Góra, at 1,725 metres (5,659 ft). The next highest mountain group is the Karkonosze, whose highest point is Śnieżka, at 1,602 metres (5,256 ft). Among the most beautiful mountains of Poland are the Bieszczady Mountains in the far southeast of Poland, whose highest point in Poland is Tarnica, with an elevation of 1,346 metres (4,416 ft). Tourists also frequent the Górce Mountains in Górce National Park, with elevations around 1,300 metres (4,300 ft), and the Pieniny in Pieniny National Park, with elevations around 1,000 metres (3,300 ft).
