Langinkoski sits about five kilometres north of Kotka's city centre on the banks of the Kymijoki river, where a significant set of rapids creates exactly the conditions salmon favour. Tsar Alexander III discovered the spot in 1880 when he was still crown prince, and returned in 1889 with a newly-built log cabin he used as a private fishing retreat. The cabin still stands — a modest, beautifully crafted structure in dense forest — and is now a museum open to visitors during the summer months.
The setting is the thing. The rapids are genuinely dramatic, the forest around the lodge is dark and quiet, and the gap between this rough log cabin and the imperial lifestyle of the period is striking enough to require thought. A small Orthodox chapel stands nearby. The site is reachable by bicycle from Kotka centre or by the Langinkoski bus route, and the walk along the river path from the parking area to the lodge takes about fifteen minutes through attractive forest.
