Believed to be the oldest town on the Iberian Peninsula, the Andalusian port of Cádiz enjoys a stunning location at the edge of a six-mile promontory. The town itself, with 3,000 years of history, is characterised by pretty white houses with balconies often adorned with colourful flowers. As you wander around be sure to take a stroll through the sizeable Plaza de Espãna, with its large monument dedicated to the first Spanish constitution, which was signed here in 1812. Cádiz has two pleasant seafront promenades which boast fine views of the Atlantic Ocean, and has a lovely park, the Parque Genoves, located close to the sea with an open-air theatre and attractive palm garden. Also notable is the neo-Classical cathedral, capped by a golden dome.

A Mediterranean city and naval station located in the Region of Murcia, southeastern Spain, Cartagena’s sheltered bay has attracted sailors for centuries. The Carthaginians founded the city in 223BC and named it Cartago Nova; it later became a prosperous Roman colony, and a Byzantine trading centre. The city has been the main Spanish Mediterranean naval base since the reign of King Philip II, and is still surrounded by walls built during this period. Cartagena’s importance grew with the arrival of the Spanish Bourbons in the 18th century, when the Navidad Fortress was constructed to protect the harbour. In recent years, traces of the city’s fascinating past have been brought to light: a well-preserved Roman Theatre was discovered in 1988, and this has now been restored and opened to the public. During your free time, you may like to take a mini-cruise around Cartagena's historic harbour: these operate several times a day, take approximately 40 minutes and do not need to be booked in advance. Full details will be available at the port.

Tangier can trace its origins back to the Phoenicians and ancient Greeks. It was named after Tinge, the mother of Hercules’ son, and its beginnings are embedded in mythology. It was subsequently a Roman province, and after Vandal and Byzantine influences, was occupied by the Arabs with Spain, Portugal, France and England also playing a part in the city’s history. With such a diverse past it is perhaps not surprising that Tangier is such an individual city. Overlooking the Straits of Gibraltar, the city lies on a bay between two promontories. With its old Kasbah, panoramic views, elegant buildings, squares and places of interest, there is much to discover in both the new and old parts of the city.

El Ferrol has been inextricably linked to the sea for more than two millennia, being a major shipbuilding centre for most of its history. From its beginnings as a tiny fishing port in the 1st century BC, it endured conquests by Vandals, Suebis, Arabs and Christians. With the arrival of the Bourbons in the 18th century, Ferrol became a leading maritime centre, largely due to its large natural harbour on the Ferrol Inlet, an arm of the Atlantic. Now a large commercial port, Ferrol is also the gateway to the northern Spanish province of Galicia, a region noted for its green mountains, deep gorges and fast-flowing rivers. It is also well placed for visiting the medieval holy city of Santiago de Compostela. Interestingly, Ferrol's city centre is modelled on Lisbon in Portugal, a country with which it has strong historical and linguistic ties. The layout comprises of a rectangle lined with six parallel streets, with two squares on each side. These squares have the city's best shops, restaurants and bars.

Lying near the head of Southampton Water, a peninsula between the estuaries of the Rivers Test and Itchen, Southampton is Britain’s largest cruise port. It has been one of England’s major ports since the Middle Ages, when it exported wool and hides from the hinterland and imported wine from Bordeaux. The city suffered heavy damage during World War Two and as a result the centre has been extensively rebuilt, but there are still some interesting medieval buildings including the Bargate, one of the finest city gatehouses in England.
