The park contains the 'Piekło' (Hell) valley, a deep ravine known for its unique microclimate and specific geological erosion patterns.
It preserves a high concentration of erratic boulders, which are remnants of the last Scandinavian ice sheet.
The park encompasses over 10 separate nature reserves, including the 'Dolina Strzyży' and 'Wąwóz Huzarów'.
It serves as a critical habitat for populations of wild boar, roe deer, and red deer that periodically move toward the urban periphery.
The terrain is shaped by the Pomeranian phase of the Vistula glaciation, resulting in high-relief glacial formations.
Several old water mills, including those along the Radość stream, are hidden within the forested valleys.
Trójmiejski Park Krajobrazowy (Tri-City Landscape Park) is a protected area spanning over 19,000 hectares, serving as a forest buffer between the urban agglomerations of Gdańsk, Sopot, and Gdynia. The park features diverse glacial terrain, including moraine hills reaching over 150 meters above sea level and deep, V-shaped valleys carved by erosion. It is characterized by dense beech and oak-hornbeam forests, which act as a crucial green corridor for local wildlife. The area hosts multiple strict nature reserves, such as Dolina Radości and Lasy nadleśnictwa Gdańsk, designed to protect rare flora and specific forest ecosystems. Visitors encounter significant topographical variety, ranging from plateau areas to steep ravines, providing a stark contrast to the nearby Baltic coastline. The park's management office is headquartered at the Matemblewska address in Gdańsk-Oliwa. It is a strictly protected landscape, meaning human activity is confined to designated hiking, cycling, and equestrian trails.

Download offline topographic maps before entering, as the dense forest cover can lead to unreliable GPS signals in deep ravines.
Stick to marked trails to avoid crossing into protected 'strict reserve' zones where human access is prohibited.
Bring insect repellent, as the humid valley bottoms are prone to high tick activity during warmer months.
Attempting to hike off-trail in the steep ravine sections without proper footwear or experience.
No littering, no open fires outside designated areas, keep dogs on leashes, and maintain silence to avoid disturbing local wildlife.
