Marvel at the sheer magnitude of it all. The charming Old Towns of Stockholm, Tallinn, and Helsinki. Copenhagen’s picture-perfect Nyhavn Wharf. St. Petersburg’s imperial grandeur and treasure trove of visual and performing arts. Marvel again at the ever-changing panorama of emerald archipelagos, fairytale castles, and immaculately manicured gardens. Six countries in a week, yet nothing feels hurried. There’s time to stroll the Nevsky Prospect for amber earrings, explore the golden age of sail on Mariehamn’s classic windjammer, and spend a day at sea relaxing with a good book and a perfect massage in the WindSpa.
