Jastarnia  is city in Pomorskie in Poland. The town is situated in the middle of the Hel peninsula. It is one of the most popular sea resorts at the Polish cost with interesting nightlife. The center is along the Ulica Sychty with a lot of bars and pubs. It leads to a big fishing harbour at the south beach. Tourist ships are starting trips to the Bay of Gdansk there.
The sea resort is not quite big, so you can easily walk on food or rent a bike. As it is situated on the Hel Peninsula its not easy to get lost.
The biggest biulding is a neobaroque church with a very interesing altar in the shape of a fishing boat. Old fishing houses are situated around the church. Some of them are turned into fishing museums (ulica Rynkowa 10 and ulica Mickiewicza 115).
A beautiful broad beach with white sandy dunes is north east of the center. A pine forest stars behind the dunes.
