Lisbon to Barcelona

From Moorish walls and Manueline carvings to elaborate azulejo tiles and Gothic arches – the traces of Lisbon’s rich history can be seen and felt simply by wandering its storied (and rather hilly) streets. But Europe’s second-oldest city is also one of its most cosmopolitan, and amid historic landmarks like Jerónimos Monastery and São Jorge Castle, you’ll find chic rooftop bars with views across red terracotta rooftops and the sparkling Tagus river, design-led concept stores selling artisanal souvenirs, and stylish restaurants serving up inventive takes on local ingredients.

The white contour of a church on a hilltop, the narrow streets of the old fishermen and tradesmen quarter, the presence of the sea and the immense beach known as Praia da Rocha identify the character of Portimao. The old town is dominated by the architecture of the late 19th and 20th centuries: houses boasting wrought-iron balconies, ornate stonework around the windows and doors, balustrades of stone and tile-covered ceramics and walls. This southern Portuguese port is the gateway to many historic towns of the Algarve region. The town offers a rich heritage of historical monuments and the eternal natural beauty of the Ria de Alvor. Portimao is also known for its extraordinary Portuguese cuisine. To savour the spirit of Portimao, there is nothing better than to sit in the shade of the trees in the gardens of Manuel Bivar, to watch the fishing boats sail by and to walk through streets and squares that exude the ambience of an active, hard-working town.

Veiled in myth, Morocco’s enigmatic port, Tangier, reveals history at every turn.

Pick out travelers’ treasures to take home in the labyrinthine alleyways of the city’s Medina, within the walls of a 15th-century Portuguese fortress.

European and Moroccan traditions intertwine in everything from the beguiling blend of medieval and modernist architecture to the food in Melilla, Spain’s North African outpost.

And when you need more sustenance than this visual feast provides, tuck into everything from tapas to dishes laced with Moroccan spices.

A day at sea with Crystal can be as relaxed or as engaging as you wish.

Cagliari, capital of Sardinia, sprawls across the hills promising awe-inspiring views for those who venture to Monte Urpinu Park. At its heart lies the historic Castello district, where a Roman amphitheater, medieval towers built by the Pisans, and a 13th-century cathedral with an intricately carved crypt sit beside the monolithic architecture of the Mussolini era. Down by the harbor, the eateries and bars in the Marina buzz with life. In Via Sardegna and Via Cavour taste local flavors such as the peppery salami mustela, salty pecorino cheese, and carta musica, a wafer-thin flatbread said to sound like music when it snaps. They all go well with a glass of cannonau or vernaccia, the island's robust wines.
