If you like visiting ruined châteaux, head north to the valley of the Orbiel. Just twenty minutes from Carcassonne is the village of Lastours. High on a ridge above the village, four separate châteaux stand in a line: Cabaret, Tour Régine, Surdespine and Quertinheux.

A gorge is a very deep crevice between two mountains or hills, formed by rivers running through and eroding rock over a very long period of time. Here are a couple to take your breath away.

I’m assuming you’ve already gasped at the Parc Güell, gazed at Gaudi, stared at the Sagrada Familia, and marvelled at Miró.
For me the charm of Barcelona is to be found in its more homely treasures, on foot or by its efficient public transport system.
