Hel Peninsula (fish smokehouses) ★ 4.5
Hel Peninsula, a 35-km sand spit reaching into the Baltic, is the Tri-City's day-trip for fishing-village food: smoked eel, salmon and halibut from working smokehouses, plus the Hel fokarium and Coastal Defence Museum.
Tip: Summer Motława ferry at 09:15 is the scenic route; train via Gdynia is faster.
