Ever since the Romans constructed a fort here and began using it as a trading post, Oporto has been a prosperous commercial centre. In the 15th and 16th centuries the city benefited from the wealth generated by Portugal’s maritime discoveries, and later, the establishment of a lucrative wine trade with Britain compensated for the loss of the spice trade. Today, Portugal’s second-largest city is a thriving, cosmopolitan place and is famous for its production of the fortified, sweet 'port' wine. Its historic centre is a UNESCO World Heritage Site and the city was also awarded the status of European Capital of Culture in 2001. A large sandbar prevents ships from sailing into Oporto itself, so for over a century they have used nearby Leixões instead, a man-made seaport constructed nine miles from the city. Leixões is one of Portugal's major sea ports and is also home to one of the country's oldest football clubs, winners of the Taça de Portugal cup in 1961.

Offering solace on the long journey across the Atlantic, Ponta Delgada is the Azores Islands' largest city, and a welcome relief for any weary sailor. Located on an archipelago of Portuguese islands, some 1,100 miles from the mainland, you can explore humbling volcanic scenery, as well as Sao Miguel's verdant landscape - which glows with colour when the hydrangeas that the Azores are known for bloom into life during the summer months. The striking black and white facade of the Church of Sao Jose welcomes you to the city itself, while you can head to the markets to pick up the pineapples, tea leaves and coffee beans that add a little flavour to the island. As the largest city of the Azores, Ponta Delgada is well stocked with places to eat delicious local seafood, or pick up a little shopping, as you enjoy setting your feet on dry land, following a long journey at sea. Volcanic firepower has carved these stunning islands, and a journey up to Caldeira das Sete Cidades is a must do, where you can hike beside the water-filled crater, and admire views of steep green walls, and the uninterrupted Atlantic Ocean stretching beyond them. Lagoa de Fogo offers yet more humbling views, with the crater lake dropping off sharply to rippled ocean far below.

Set on the five-sided island of Faial, Horta is decorated with a colourful cacophony of artworks, which have been daubed across its concrete marina by visitors from around the globe. Left behind by sailors, they tell thrilling stories of life on the high seas. Sitting in the midst of the vast Atlantic, 1,100 miles away from the Portuguese mainland, Horta is the ideal pit-stop for yachts traversing the Atlantic, and one of the world's most visited marinas. The tapered, imposing peak of the Pico volcano, on neighbouring Pico Island, provides a glorious backdrop to the jostling yacht masts of the marina. For the ultimate view, however, you'll need to head up to Faial's own volcanic treasure - Caldeira. Look out from this colossal crater, to absorb the extraordinary views, and a demonstration of a volcano's ability to create as well as destroy. The crater is a natural reserve that blooms with wildflowers and lush green scenery, and scattered sky-blue hydrangeas. Flowers spread colour right across these islands - and you can learn more about the native species at the Faial Botanical Garden.

Formed by a volcanic eruption, Madeira lies in the Gulf Stream, about 500 miles due west of Casablanca. Discovered by Portuguese explorer João Gonçalves Zarco in 1419, this beautiful island became part of Portugal’s vast empire and was named for the dense forest which cloaked it - 'Madeira' means 'wood' in Portuguese. Sugar plantations first brought wealth here, and when King Charles II of England granted an exclusive franchise to sell wine to England and its colonies, many British emigrants were drawn to the capital, Funchal. Today’s travellers come to Madeira for the varied and luxuriant scenery, from mountain slopes covered with vines to picturesque villages and a profusion of wild flowers. The natural beauty of the island has earned it many pseudonyms such as ‘The Floating Garden of the Atlantic’, 'The Island of Eternal Springtime' and ‘God’s Botanical Gardens’ and our selection of excursions aim to show you why.

The largest of the Canary Islands, Tenerife is a beautiful and scenic island which enjoys year-round sunshine and is dominated by Mount Teide. The mountain range runs through the centre of the island, with fertile valleys on the northern side. In the central part of the range is the gigantic natural crater of the Cañadas del Teide, about 14 miles in diameter. Santa Cruz, the island’s pretty capital, was originally a small fishing village but has now grown into a modern city, and also contains 16th-century civic buildings and ornate private mansions. Near the pier is the Santa Cruz Palmetum, a Botanical Garden covering an area of 29 acres, specialising in palms.

Perhaps the prettiest of the Canary Islands, Gran Canaria is an almost circular isle with the peak of Pozo de Las Nieves, its highest point, at the centre. With a wealth of natural beauty and all the exciting attractions of city life in the capital, the island offers the best of both worlds. You will no doubt wish to see the sights of the capital’s old quarter, which dates back to the 15th century and encompassses the Vegueta and Triana districts, and wherever you go you can enjoy the glorious subtropical climate, perfect for growing exotic palms and fruits.

A volcanic island designated a UNESCO Biosphere Reserve, Lanzarote’s dramatic landscapes were shaped by an explosive past. Today, its pretty beaches and virtual absence of rain together with duty-free shopping make the island an extremely desirable destination. The main port and capital, Arrecife, is a pleasant town with a modern seafront and colourful gardens. Outside the capital there is plenty to explore, from the dazzling white salt flats of Janubio and the rugged terrain of Fire Mountain to the eerie caves of Los Verdes and an array of unspoilt fishing villages scattered around the coast. The island is home to a great selection of restaurants and local specialities including garbanzos compuestos – a chickpea stew; papas arrugadas – potatoes with carrots, peas, ham and green pepper; and of course, plenty of fresh seafood. Please note that those planning to participate in one of the shore excursions from this port may need to take an early lunch on board ship to suit the excursion schedules.

Dating from Roman times, the Galician city of Vigo has a fine natural harbour and is renowned as the biggest fishing port in the world. It is also full of history - it was in this fjord-like quay that the English and Dutch defeated the French and Spanish fleets in 1702. Today, the attractive marinas stand in contrast to the industrialised areas of the city, while further exploration will reveal the characteristic 17th-century architecture and attractive countryside beyond. The charming Old Town is a delight, with its labyrinth of winding narrow streets and shaded squares. Nearby is the Cathedral city of Tui, and further to the north is the pilgrimage centre of Santiago de Compostela, which can be reached by car in approximately 1¼ hours.

Just 22 nautical miles down river from the Tower Bridge in London, Tilbury is a popular turnaround port for cruises visiting Baltic and Northern European destinations.
