Kotka.

Kotka is a dynamic coastal city built on islands at the mouth of the Kymijoki River where it flows into the Gulf of Finland, creating a landscape defined by water, bridges, and maritime heritage. The city serves as Finland's main port, giving it an international character and seafaring atmosphere. The Eastern Gulf of Finland National Park surrounds the city with pristine archipelago nature, accessible by boat for exploring rocky islands and observing seabirds and seals. Kotka's parks are exceptional, particularly the Sapokka Water Garden with its waterfalls and artistic landscaping, and the riverside Sibelius Park. The city center features Art Nouveau architecture and the impressive Orthodox Church of St. Nicholas. Excellent salmon fishing in the Kymijoki River and proximity to untouched coastal nature make Kotka ideal for combining urban comforts with wilderness experiences in the Gulf of Finland archipelago.
