Crossing the Frozen Sea to Suomenlinna Fortress

Suomenlinna Sea Fortress is the only UNESCO site in Helsinki. The fort is currently a frozen haven for exploring with three large islands to walk around and some beautiful sights of the decommissioned snow covered forts to be seen. The ferry has a small cost but there is no admission fee to the islands. This early morning ferry was pushing through the frozen sea to make the short 15min journey. 📍Suomenlinna, Helsinki, Finland #suomenlinna #helsinki #finland #finlandtravel #frozen
