Those up for physical activity and a tad bit extreme outdoor pursuits should definitely try canyoning in Reunion.

Enclosed within a protective wall reaching up to 20 metres in width, the Ciudad Amurallada (or Walled City) is Cartagena's old beating heart. Packed with well-preserved colonial buildings, it's a pleasure to stroll through; its streets of colourful low-rise merchant homes marked by iconic balconies are now mostly walked by either tourists or students who attend classes at the University of Cartagena during the day and linger for meals and nightlife after school is out. Cafes in Plaza Aduana and Plaza Santo Domingo teem with patrons, forging an incredibly jovial atmosphere; the districts of San Diego and El Centro are two not to be missed. There is plenty of food and shopping to be had, with a mixed bag of world-class restaurants and street food hawkers and the incredibly photogenic palenqueras — women dressed in vibrantly coloured clothing selling fruit in the streets — images of whom have become emblematic of Colombia as a travel destination.

Oudayas Kasbah near Rabat's nedina has kept its old cannons placed on a bastion. Its massive gate is entirely carved, while its blue and white walls give it a Mediterranean atmosphere. Cobbled streets lead to the El Atiqa Mosque, the oldest in the city, and on to the old semaphore platform. The view from here, or the terrace of the neighbouring Café Maure, is splendid: Rabat, nearby Salé and Bouregreg river meeting the ocean. The Oudayas Palace, further on up, which now houses the National Museum, has conserved its markedly simple and balanced original decor. The Andalusian Gardens below are a heaven of peace full of fruit trees, rose-laurels and cascades of bougainvilleas.
