Board Columbus for our afternoon sailing from Tilbury, and enjoy your first evening on board.
Today is spent at sea, as Columbus cruises into northern waters.
Today Columbus docks in "wonderful, wonderful" Copenhagen. Stroll the stylish streets, or enjoy an optional excursion taking in the famous sights, including the famous bronze statuette of the Little Mermaid. Watch the world go by from a harbour-side bar in Nyhavn, and don't miss the sculpted walkways of the world-famous Tivoli Gardens.
This morning Columbus arrives in Rostock. Seat of northern Europe's oldest university, Rostock retains much of its medieval charm in the gabled houses and preserved warehouses surrounding Neuer Markt, the city's main square. However, for many the main attraction of this stop will be the optional excursion to Berlin. See the arch of the Brandenburg Gate, the Unter den Linden, the former East German sector and the shops on the 'Ku'damm', and visit the reminders of 20th-century conflict - from Hitler's Bunker to Checkpoint Charlie.
Spend the day at sea, enjoying Columbus' wonderful array of on-board entertainments.
Almost impossibly beautiful, the Estonian capital, Tallinn, with its enchanting and unspoilt old town, is one of Europe's most scenic cities. Discover this timeless gem, with its winding cobbled streets of storybook houses, spectacular steepled churches, ancient buildings and Toompea Castle.
Columbus will spend two days at the docks of St Petersburg, one of the world's most startling and glorious cities, with its world-renowned Hermitage Museum, its wide canal-side boulevards and its modern cosmopolitan atmosphere.
Days Seven and Eight
We'll have lots of time in the city, so don't miss our optional excursion to the Tsars' Summer Palace at Petrodvorets, the chance to explore the city's Haymarket, or the opportunity to see the opulence of the Mariinsky Theatre, home to the world-renowned Kirov Ballet.
This morning's destination is the wonderful port of Helsinki, where the City Hall overlooks the fresh fish stalls and historic, covered Market Hall in Market Square. Stroll through Esplanade Park, and take in the panoramic views of the city and the sea beyond from the cathedral tower before we set sail once more in the afternoon.
Columbus' third Scandinavian capital is Stockholm. Best explored on foot, the Swedish capital spans 14 islets and boasts a wonderful mix of historic sights and fine city parks. Its ancient heart is Gamla Stan, a beguiling labyrinth of cobbled streets, shops, cafes and restaurants.
Spend another day at sea, hopefully enjoying sunny skies, as Columbus heads back to the UK.
Settled for over 1000 years, Denmark's lively second city, Aarhus, is a delightful university seat boasting a cobbled old town of colourful shops, bars and cafes, all watched over by the imposing Gothic Domkirke cathedral. Don't miss the fascinating Viking Museum.
Make the most of your final day on board as Columbus cruises to London and home.
Marco Polo arrives back in Tilbury at the end of a wonderful cruise around the Baltic.
British Citizens will need a full, 10-year passport to travel on this cruise. Since some countries require visitors to be valid for at least six months after the return date of the cruise we recommend that all customers ensure that this is the case. Holders of non-British passports should check with the relevant embassies to see if any requirements and restrictions exist for any countries visited during the cruise.
