A look back at Timothy West and Prunella Scales' travels in Sweden, where they finally fulfilled their lifetime ambitions of crossing the country coast-to-coast by boat. The 350-mile journey takes in the mighty Göta Canal, Sweden's three biggest lakes, the islands of the Swedish Archipelago, and the Baltic sea - a huge challenge for any sailor let alone two octogenarians more used to the Kennet and Avon Canal. Even the relaxation is testing - a Swedish sauna with an icy plunge into the waters of the canal, but the long tranquil summer days, island-dotted lakes, and woodland glades make it Tim's favourite-ever trip.

Timothy West and Prunella Scales share some memories of their canal journeys overseas, including their first trip, which was to France on the Nivernais Canal. Tim is reminded of the time he tried to park his boat in Venice, at St Mark's Square, and the couple reminisce over a moonlit gondolier trip down the Grand Canal. Having successfully mastered the waterways of Europe, Tim and Pru then set forth on even more ambitious and remote journeys across the world - to India, Canada, Argentina and a trip down the Nile.

Timothy West and Prunella Scales embark on an epic adventure along one of the greatest achievements of British canal engineering. It's a world heritage site, and historically highly significant, yet very few people in this country have ever heard of the Rideau Canal. Heading 3000 miles from their London home, Tim and Pru arrive at Kingston, Canada, where the Rideau begins. Wending its way through the backwoods of Ontario, the Rideau links rivers and vast lakes to create a waterway that connects Lake Ontario with the city of Ottawa. Tim and Pru follow its 125-mile course, all the way to Canada's capital. En route, they take in Fort Henry; a lakeside resort; and navigate the famous Ottawa lock. They also discover the huge human cost of the canal's construction and meet with descendants of the Algonquin guides who helped with the build.

Timothy West and Prunella Scales return to the English canal system as they navigate the Lancaster Canal. An early masterpiece of the waterways, 'The Lanky' wends its way north, through the city of Lancaster and along the coast at Morecambe Bay. The waterway is largely rural, running through rolling open countryside and deep woods. It also boasts one of the most elegant pieces of canal architecture in the country, the Lune Aqueduct. When their journey reaches Carnforth, Tim and Pru visit its train station, which was used as the key location in the film Brief Encounter. This is a very personal voyage for Pru. Long-forgotten memories rise to the surface as she visits the lakeland village of Near Sawrey, where her family lived during much of the war and as a child she once saw Beatrix Potter.

Timothy West and Prunella Scales embark on their first Latin American adventure and head for Argentina. A few miles from Buenos Aires, lies a vast labyrinth of canals and rivers that meander ever deeper into the jungle. Hiring a traditional cargo boat, known as a chatta, Tim and Pru voyage into the remoter corners of the Paranß delta. 'When you're my age, a trip from Wandsworth to Putney on a 37 bus can seem quite an adventure,' remarks Pru. 'And here I am in South America on a tramp steamer, heading into the jungle - I mean I can't believe it.' Tim and Pru discover the Belle Epoque splendour of the jungle town of Tigre. They visit a remote enclave of Anglo Argentines, who still drink G and T and toast the Queen. They also learn about the 'dirty war' of the 1970s. They marvel at the local flora and fauna and admire the hummingbirds, and perform Argentina's national dance.

Tim and Pru decide that they've had enough of kicking their heels at home in Wandsworth and head off to explore one of the world's great waterways, the River Nile. At first Tim is unsure, but Pru is determined: '...all the journeys I've done with him have opened doors for me and given me new and thrilling experiences'. Travelling from Luxor to Aswan, Tim and Pru uncover the secrets of this great artery of an ancient civilisation and discover how some of the first-ever canals were used to build the temple at Karnak. They also visit a Nubian village; purchase aphrodisiacs in the souk; and dance by moonlight.

Timothy West and Prunella Scales return to Wales to explore a canal that has eluded them for over half a century. The famously beautiful Monmouthshire and Brecon canal is cut off from the rest of Britain's network of waterways by the Black Mountains. The isolated gem meanders its way through the tranquil Usk valley. Tim and Pru visit the old iron works at Blaenavon, where children as young as five were once put to work; and the beautiful 15th-century castle at Tretower - rumoured to be haunted. They also lend a hand with some lock restoration work.

The Douro's dramatic geography is unlike any of the other waterways Tim and Pru have experienced - with the deepest lock in Europe and sites of ancient historical importance. Tim and Pru visit the Factory House, a very traditional English gentlemen's club that lies in the heart of bustling Porto. They also follow the water route taken by Baron Forrester, the Yorkshire born port entrepreneur, and visit some stunning wine estates.

Timothy West and Prunella Scales set off on their adventure along the French canal system, as they travel down the Marne-Rhine Canal in Alsace and Lorraine, close to the German border. Their journey takes in enchanted forests and fairy-tale castles; mountains and valleys; the baffling French lock system; local wines; and a visit to Strasbourg and the European Parliament.

Timothy West and Prunella Scales continue their journey exploring the Highlands and islands of Scotland, navigating their way through two of Britain's most remote canals. Having already crossed Scotland on the Caledonian Canal, they face the open sea as they island hop their way through the Hebrides, bound for the Crinan, a rarely travelled canal described by some as the world's most beautiful shortcut. Tossed around by the Atlantic waves off the coast of Mull, they are forced to head back to the safety of Tobermory. They eventually visit the holy island of Iona, the Isle of Jura, and lastly the magical nine-mile Crinan on the Mull of Kintyre.

Timothy West and Prunella Scales embark on a journey into their pasts, via the Leeds and Liverpool Canal, which celebrates its 200th anniversary this year. Despite living most their lives in the South, they both have Northern roots, and as the canal winds over the Pennines and down through the Dales they're transported back to their Yorkshire origins. Starting at the highest point of the canal, they're immediately faced with the challenge of a bumpy ride through Foulridge Tunnel. Emerging on the other side, Pru steps back into her childhood memories when they visit the country's last surviving steam-powered textile mill. Meandering through the 'curlies', the canal's most winding and beautiful stretch, they are joined by the acclaimed poet, Simon Armitage, whose work is inspired by the rugged beauty of the Yorkshire landscape.

Tim and Pru explore a network totally new to them as they embark on a voyage across the Netherlands. Travelling from the Windmills of the Kinderdijk to the vibrant city of Amsterdam, they explore a country that was partly created by its canals. Half the land was once under water, and it's the combination of windmills and canals that over the centuries prevented the Netherlands from flooding. The voyage takes them to the gardens of Keukenhof, where seven million tulips are on display. There they discover why in the 17th century, one tulip bulb cost the same as a house in Amsterdam. In the city of Haarlem they visit the Teylers Museum, which agrees to open up its archive of rare Rembrandt self-portraits for Tim and Pru to admire. Arriving in Amsterdam, they explore the capital's historic canal district known as the Grachtengordel. Braving Amsterdam's crazy canal traffic they visit one of the most elegant canal-side mansions of Holland's Golden Age.

Timothy West and Prunella Scales embark on more spectacular canal journeys. This time they travel to Venice. The journey begins 14 miles west of Venice on the Brenta, a river that was first canalised in the 13th century. Lined with palaces that were once holiday homes for Venetian nobility, they follow the route that Casanova and Lord Byron took to the city. After crossing the Venetian lagoon, Tim and Pru arrive at St Mark's Square, where they escape the busy Grand Canal and discover the tranquillity and beauty of the smaller canals that tourists rarely see. Their journey's end is on the marshy island of Torcello, the place where Venice began.
