Slowinski National Park
Słowiński National Park  (pronounced 'swo-vinski'; in Polish: Słowiński Park Narodowy) is a National Park in Poland in Pomorskie next to the Baltic Sea. The Park features unique shifting sand dunes, woods, lakes and a long coastline with a beach, and is designated in the UNESCO list of World Biosphere Reserves.
There is an entrance to the National Park around 3km west of Łeba. There are bicycle rental shops in Łeba (around 20zl to rent one bike for a day).
To get to Łeba, you can take the minibus from Lębork railway station. The Lębork-Łeba route is served by frequent minibuses operated by Boguś Bus  and the journey is around 45 minutes. Both PKP Intercity  and SKM  trains from Gdańsk and Słupsk stop at Lębork.
After getting off the minibus at the railway station in Łeba, continue walking straight ahead to the roundabout at the end of the road. Turning left at the roundabout takes you down a road which leads you to the entrance of the National Park after around 3 km. Turning right at the roundabout will take you into the town centre of Łeba where you can hire cycles and find places to eat and stay. The tourist information centre in Łeba is on the right hand side of the road next to the library after turning right at the roundabout.
Between 1 May and 30 September, there is an entrance fee of 6zl per person (adults) and 3zl per person (school pupils, students, pensioners, disabled people and active duty soldiers) to enter the National Park. Entry is free for children under the age of 6.
One of the best ways to explore the Park is by bicycle - see the Get in section above about renting cycles.
When entering the National Park from Łeba, as you go down the cycling/foot path, the Łebsko Lake is on your left while the Baltic Sea and coastline are on your right beyond the woods. The big sand dunes are located at the end of the cycling/foot path, around 10km west of Łeba.
In the summer peak season, there are cruise boats on the Łebsko Lake.
There are around 170 km of walking trails in the National Park.
Remember to take insect repellent as there are many mosquitos.
