After breakfast, join your leader on an orientation walk around Finland’s capital city. Once you get your bearings, the rest of the day is free to explore Helsinki as you wish. Maybe check out the UNESCO World Heritage-listed Suomenlinna Sea Fortress, located just a ferry ride away on a group of islands off the coast of Helsinki. The fortress was originally built by the Swedish to protect against Russian expansion. You could also acquaint yourself with Finnish sauna culture by visiting a public sauna to unwind. This evening, board the famous 'Santa Claus Express', a comfortable overnight train to Rovaniemi, known to many as the hometown of Santa Claus.
