GULF OF FINLAND - GULF OF PERNAJAN
Pernajanlahti and its archipelago is one of the largest inland bays in the Gulf of Finland. It is characterised by highly variable salinity. At the mouth of the Koskenkylänjoki River, the water is almost fresh, and all species that require salt in the Baltic Sea are found at the southern edge of the bay. The area is rich in birdlife and has several bird sanctuaries. Waterfowl are abundant in spring as they search for suitable nesting sites. It is also possible to spot white-tailed eagles and ospreys.
