Porvoonjoki

Porvoonjoki is a river in southern Finland that flows through the Uusimaa region and empties into the Gulf of Finland at the town of Porvoo. It is a coastal river that has helped shape the landscape and development of eastern Uusimaa and the historic Porvoo region.

The river rises in inland lakes and runs toward the Baltic Sea, passing through rural farmland, forests, and the urban area of Porvoo. The valley is relatively varied, producing diverse habitats along its course and providing scenic views for residents and visitors alike.

Historically, Porvoonjoki supported timber floating and served as a transportation route for goods between inland settlements and the coastal market. Several mills and small industries operated along its banks, and the river helped connect Porvoo to regional trade networks.

In modern times, the river is used for recreation and tourism. Boating, kayaking, fishing, and riverside promenades are common, particularly near Porvoo’s well-preserved old town. Environmental management focuses on water quality, habitat restoration, and the protection of aquatic and riparian ecosystems.

The Porvoonjoki remains a defining feature of Porvoo, contributing to the town’s historic character and attractiveness as a visitor destination. It is also part of local identity and landscape planning in the surrounding municipalities.
