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.

The original settlement formed on the site of Casablanca by the Berbers became the kingdom of Anfa, and during the 15th century harboured pirates who raided the Portuguese coast. In retaliation for the attacks, the Portuguese destroyed Anfa and founded the town they called Casa Branca (white house). They remained here until an earthquake in 1755 and the town was subsequently rebuilt by Mohammed ben Abdallah, whose legacy of mosques and houses can still be seen in the old Medina. Casablanca acquired its present-day name when the Spanish obtained special port privileges in 1781. The French landed here in 1907, later establishing a protectorate and modelling the town on the port of Marseilles. Today Casablanca is Morocco’s largest city, its most significant port and the centre of commerce and industry. The city is a vibrant fusion of European, African and Arabian influences and its French colonial architecture and art deco buildings seamlessly blend in with the busy, colourful markets. Please note that vendors in the souks can be very persistent and eager to make a sale.

Also known as ‘La Isla Bonita’ (the beautiful island), La Palma is typified by lush forests of pine, laurel and fern which contrast with the rugged splendour of the gigantic Taburiente crater. The island is dotted with attractive villages, which are a delight to discover, and the capital Santa Cruz also makes for an interesting day of exploration. Perched on the edge of the volcanic crater of La Caldereta, Santa Cruz comfortably blends modern architecture with old colonial buildings. Perhaps visit the fascinating Natural History Museum, stroll around the historic quarters and the Plaza de Espana or travel a few miles outside the city to the exquisite Church of Our Lady. If you enjoy shopping, you can find reasonably priced silver jewellery, leather goods and beautifully embroidered clothes, tablecloths and napkins, a speciality of the Canary Islands.

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.
