Trip Details The North Europe cruise package includes seven nights aboard the Costa Mediterranea, an 86,000-ton ship featuring 17th- and 18th-century Italy motifs as well as elements from Mediterranean Sea mythology. The vessel also boasts the ornately decorated Maschera d'Argento Atrium, which spans 10 decks.

The ship sets sail in Copenhagen, the Danish capital, at 7 p.m. You'll spend a night on the sea before arriving at your first destination, Tallinn, Estonia. The history here is interesting. After only a brief period of independence, interspersed with a succession of foreign rulers, including the Danes, Swedes, Germans, and Russians, Estonia finally regained its independence in 1991. The country's capital, Tallinn, is a full-blown metropolis, famous for its historical landmarks, music festivals, and sailing.

Sightseeing attractions include a 13th-century fortification at Toompea hill and the Gothic Town Hall, which is topped with a weather vane of the town's symbol, Vana Toomas, which dates back to 1530. Its rich history aside, Estonia is known for its intricate embroidery, leatherwear, and ornate jewelry. Explore the city on your own or opt to join a guided sightseeing tour, which starts from €48 for an adult and from €34 for a child (ages 4-14) for a 3.5-hour excursion.

The next stop is St. Petersburg, Russia's second city, built in the delta of the Neva River. Some of the city's most recognizable sites include the Peter and Paul Fortress on Zayachy Island in the Neva River and the Hermitage art museum, with its Russian-baroque-style Winter Palace. Be sure to visit Nevsky Prospekt, a popular street that counts as the city's commercial and cultural center. Optional guided sightseeing starts from €53 for an adult and from €37 for a child for a 3.5-hour tour.

From St. Petersburg, you'll sail to Helsinki, the capital of Finland. Here you can admire the landmark architectural work by local designer Alvar Aalto, such as the music venue Finlandia Hall. Other attractions include the Presidential Palace, the Lutheran cathedral in Senate Square, the Temppeliaukio Church, and the Uspenski Orthodox Cathedral. You could also take a ferry shuttle to Suomenlinna Island, home to the ruins of an 18th-century fortress. Organized tours start from €53 for an adult and from €37 for child for a 2.5-hour tour of the city by coach. Each tour is followed by a boat cruise along Helsinki's canals.

Hop back on the ship and leave Helsinki for Sweden's capital, Stockholm, a 14-island part of the archipelago on the east coast where Lake Mälaren meets the Baltic Sea. Cultural and historical attractions abound here, partly because this city luckily escaped bombing during World War II owing to the country's neutrality.
