Gdansk Trip (Oct 13-15)Gdansk, Sopot and Gdynia are collectively known as the Trojmiasto (Tri-City). Together, they dominate the coastal vantage point of northern Poland along the Baltic Sea. Man this trip has almost everything. From cobblestone-paved towns, churches, monuments to sandy beaches and nice long boardwalks, we even had the chance to take a short hike up the hill to catch an aerial view of Gdansk.
