Pomeranian Coast (Trójmiejski Park Krajobrazowy)
The Trójmiejski Park Krajobrazowy sits between three cities and belongs to none of them. Its beech and pine forests run along moraine ridges left by retreating glaciers, dropping sharply — slopes here exceed forty degrees in places — into flat-bottomed valleys where alder and willow crowd the streams. In the evenings, red deer move across the hillsides. In June, wild strawberries appear at the edges of grassy paths.
This is a landscape park in the literal sense: nearly 20,000 hectares of post-glacial terrain wrapped around the Tricity metropolitan area of Gdańsk, Gdynia, and Sopot. You can enter from a suburban train station and within twenty minutes be walking a ridge with no city in sight.
💛 What travellers fall for
People who know the park well tend to time a walk for late afternoon in summer, when the light drops into Jaśkowa Dolina and the deer start to move. The yellow-marked Trójmiejski Trail is the spine most return to — 46 km from Gdańsk to Gdynia, but easily broken into single-valley sections.
How Pomeranian Coast (Trójmiejski Park Krajobrazowy) came to be
The park was established on 3 May 1979, by resolution of the Voivodeship National Council in Gdańsk — one of the earliest landscape parks created in Poland, at a moment when rapid post-war urban growth was pressing hard against the forests and moraine hills surrounding the Tricity area. The founding area of 20,104 hectares was drawn specifically to protect the post-glacial terrain, the valleys, and cultural sites that were at risk of disappearing under expanding suburbs.
Boundaries have shifted modestly since: a small expansion in 1994 brought the area to 20,312 hectares, then a 1998 revision reduced it to 19,930 hectares while establishing a buffer zone of 15,208 hectares. Within those limits sit ten nature reserves, 167 natural monuments, and landmarks that predate the park by centuries — among them a 16th-century water forge in the Valley of Powaga in Oliwa, and the Kalwaria Wejherowska pilgrimage complex, founded in the second half of the 17th century.
