Hel is city on the end of Hel peninsula in Poland. It is surrounded by the sea from all sides beside the peninsula and therefore a perfect water sport center. The settlement was first mentioned in the early Middle Ages and its inhabitants lived on piracy. In 1266 Hel received its town charter which was affirmed in 1378. From 1454 until the Second Polish Partition in 1793 Hel was a private property of the city of Gdansk. After World War One Hel was the biggest Polish fishing harbour and defended itself for other one month against the German invaders in the beginning of World War Two.
The only way on land you can take is along the peninsula. The city is pretty small so you can get on foot everywhere. The main road is the Ulica Wiejska with a lot of cafes, bars and souvenir shops. Its fine buildings are from the 19th and early 20th century. The south boulevard leads from the old military harbour to the new harbour, where tourist ships leave for a trip on the sea.
There is an interesting Museum of Fishery in the 15th century Gothic St. Peter and Paul Church. From the top of the church tower you have a wonderful view other the city, the beaches and the sea. The museum is open 10AM-6PM.
At the south boulevard there is the Sealarium of the Gdansk University. There are performances for tourists but the goal of the basin is to grow the seals and to set them free. The seals are fed from 9AM-3PM.
Museum of Coastal Defense with very interesting Blockhouses and exhibits. 
An open-air-museum of the Polish Navy can also be visited from 9AM-4PM. You are allowed to enter the exhibits.
In the pine forest north-west of the city there are old WWII trenches and bunkers. You can climb right into the bunkers, but look out for the barbed wire strung along the ground in some places.
The white sandy Big Beach is situated in the north of the city near the pine forest. A big (41,5 metres) lighthouse of brick stone can be climbed. It was a place of severe fighting between the German invaders and Hel defenders in September 1939. There is a beautiful view from the top.
