Baltic Discovery – Helsinki & Tallinn

About this cruise

This one leaves Copenhagen on August 22, 2026 and spends 7 nights visiting Kiel, Warnemünde (Rostock) and Gdynia (Gdansk), with additional stops along the Baltic at a pace where every day has something going on but there's always time to just sit and watch the water too. You get off in Helsinki, which is a good excuse to tack on a few days on land. Every single day is a port day. 7 stops with no sea days in between. You're busy from start to finish. The route threads through 6 countries along the Baltic coast: Germany, Poland, Lithuania, Sweden, Estonia and Finland. Most ports give you about 10 hours, so you can do more than just tick off the main sights. As for the ship itself, There are 13 restaurants on Norwegian Sun, so you'd need to double up a few evenings to try them all in 7 nights. It's peak season, so the weather is at its best and the ship will be full. That's part of the fun. 7 nights of not thinking about anything except where to eat next. That's the pitch.
