Suomenlinnan Pursiseuran (SuPs) satama Marina

This marina belongs to the Suomenlinnan Pursiseura sailing club and sits right on Suomenlinna, the UNESCO-listed sea fortress island just off Helsinki's coast — making it one of the most atmospheric places to tie up in the whole country. You're essentially mooring inside a living historic monument, with old stone fortifications, museums, and centuries of naval history all around you. The club has a solid reputation for welcoming visiting sailors at fair prices, and the ferry connection to Helsinki's Market Square runs regularly so you can easily head into the city.
