From April until October Żegluga Gdańska (058 301 4926; www.zegluga.gda.pl) runs pleasure boats and hydrofoils from Gdańsk’s wharf, near the Green Gate, to Sopot (one way/return 44/60zł), Gdynia (52/70zł), Westerplatte (29/43zł) and across the Gulf of Gdańsk to the fishing village of Hel (60/76zł). Concession tickets cost about two-thirds of the normal fare, but are not available on the hydrofoils.
Another way to go to Hel is aboard the Ferry Tram (Tramwaj Wodny; Map p408; www.ztm.gda.pl/ferry), which departs from a point further up the wharf to Sopot (adult/concession 8/4zł, four daily) and Hel (16/8zł, three daily) each weekend during May and June, then daily from July to August. Bicycles cost an extra 2zł to transport.
The paddle-steamer company Żegluga Pomeranka (058 301 1300), leaving from a similar location, also runs regular boats to Westerplatte (one way/return 20/30zł) from May to September, usually including a visit to the port.
From the same departure point, Ustka-Tour (0501 571 383) operates cruises to Westerplatte (adult/concession return 30/20zł, six daily) aboard the Galeon Lew, a replica 17th-century galleon.
These are a slower means of transport than the SKM but cover more ground, running from 5am until around 11pm, when a handful of night lines take over. Fares depend on the duration of the journey: 1.40zł for up to 10 minutes, 2.80zł for 30 minutes and 4.20zł for one hour. A day ticket costs 9.10zł. Remember to validate your ticket in the vehicle, so it’s stamped with the date and time.
Gdańsk’s busy traffic isn’t much fun to drive in, but if you’d like to hire a car for some day trips in the surrounding region, contact Pol-Rent (0601 502 501; www.polrent.com; ul Długa 67/68; per day from €25).
A commuter train, known as the SKM (Szybka Kolej Miejska; Fast City Train), runs constantly between Gdańsk Główny and Gdynia Główna (4zł, 35 minutes), stopping at a dozen intermediate stations, including Sopot (2.80zł). The trains run every five to 10 minutes at peak times and every hour or so late at night. You buy tickets at the stations and validate them in the big yellow boxes at the platform entrance (not in the train itself), or purchase them prevalidated from vending machines on the platform.
