The museum is located in the gothic post-evangelical church from 16th century. After WW 2nd museum - now you can see there almost everything: pictures, tables, models, old exhibits of boats, trawlers, fish and other animals (e.g. porpoise, Baltic whales, related to dolphin).
But probably the most attractive for statistic tourist is the tower of the former church, from where there is a nice view of the town, haven and "small beach".
Entrance (2004): ~1 euro / person (1,5 with entering the tower). Special charge for photo/video.
In the former historic, 15th c. church, the Museum of Fishery is seated. At the Museum, you can see the only open-air display of old fishing boats in Poland. Close by is also the seal aquarium where you can see the baltic seals, and buy all kinds of seal-inspired stuffed animals and t-shirts to help the cause. The shop that donates its proceeds to the seal cause is "Jantar" on ul. Wiejska 121.
This rusty wreck is located on the pier. Unfortunately, you won't be able to take a lovely picture like this one, because the wreck has been scrapped. The pier is huge, and serves as the docks and harbor for Hel. Here you can check out everyone else's boat, and also catch one of the touristy ships that take people on a little tour around the peninsula, or to Sopot, Gdansk, or Gdynia.
There are a few ships leaving every hour from the pier that take you on a trip around the peninsula. Believe me, you'll hear it loud and clear when they're leaving thanks to their megaphone advertisements. Sandra costs $3.75 and the trip is an hour long. It's pretty fun, but gets very cold sometimes. For that cheap, it's worth a try! You buy the tickets right on board. If you want to take a ship to Gdynia, Sopot or Gdansk, however, you have to buy your ticket in the little booth at the entrance to the pier.
The church of St. Peter and Paul in Hel is a gothic one and was built in XV century. There is a Museum of Fish now in the church.
Strolling through the main street you will find some renovated Fisher Houses. Have a look inside. In some of them there are souvenir shops.
For this purpose try for example go in evening at the "Great Beach". Of course, sunset on the sea is a kind of banality, but it is still a must-see.
Here's as good of a shot as I got of the pier. It's very big, and on a clear day you can see Poland on the other side of the gulf from the right side.
