Sandwiched between the Namib Desert and the wild Atlantic coast, the geographically isolated town of Lüderitz is notable for its surreal Art Nouveau architecture. Most of these colourful buildings date back to the diamond rush period of the early 20th century, when Namibia was a German colony.

Walvis Bay is situated on the edge of a tidal lagoon, sheltered from the Atlantic by a long sand spit. This important wetland area is famous for its birdlife, home to one of southern Africa’s largest flamingo colonies, and it’s a short drive to the city of Swakopmund, known for its quirky German colonial architecture.

Bustling Cotonou is Benin’s biggest city, and the nation’s capital in all but name. We recommend taking an excursion out to the nearby town of Ouidah, a key transit port for the West African slave trade, where you can learn more about this dark period in human history.

Lomé is Togo’s capital and largest city, once known as the ‘Pearl of West Africa’, and there are still some architectural remnants of the colonial period, when the city was part of German Togoland. Perhaps more interesting today are Lomé’s colourful fetish markets, where you can learn about the role of Voodoo in West Africa.

Banjul is the capital of The Gambia, Africa’s smallest country, situated at the point where the Gambia river enters the Atlantic. City highlights include the National Museum and the bustling Royal Albert Market, and the nearby Tanji Bird Reserve attracts ornithologists from around the world, with hundreds of colourful species.

The busy, dusty streets of Senegal’s capital Dakar are filled with life and colour, noises, smells and local music. The people here are friendly and helpful, so expect a warm welcome – but watch out for the usual hustles and scams of a busy city.

Said to have the world's most perfect climate, cosmopolitan Las Palmas is the capital of Gran Canaria and the largest city in the Canary Islands. The charming old quarter, La Vegueta, is where you'll find the city's most interesting colonial architecture, while beach fans should head for lovely Playa de las Canteras.

In recent years Lanzarote has begun to shake off its mass market reputation and reinvent itself as a more upmarket destination. The extraordinary volcanic landscapes and the works of local artist César Manrique give the island a unique appearance, and the understated capital, Arrecife, is well worth exploring.

Bustling and modern, fizzing with industry and commerce, Casablanca is often overlooked in favour of Morocco’s better known tourist draws. But then this is part of its appeal: it’s an authentic and unvarnished city, and it’s also home to the spectacular modernist architecture of the Hassan II Mosque.

Sovereignty of ‘The Rock’ has been a thorny issue ever since Gibraltar was ceded to Britain in 1713, though on the ground it’s clear where most locals’ sympathies lie. Gibraltar is often described as ‘more British than Britain’, a curious enclave of red postboxes, double decker buses and chip shops.

Melilla is a post-colonial oddity, a Spanish enclave on the north coast of Morocco. The city is a fascinating blend of Spanish, Moorish and Berber influences, with an impressive collection of modernist buildings, plenty of bustling tapas bars and an atmospheric walled old town, the Medina Sidonia.
