A morning walk along the iconic Las Ramblas should be the sovereign cure after 22 hours on an aeroplane. Not so. Whilst the trees are shady, the crowds are thick, and the park benches too few. Fortunately, half way along is the historic la Bocqueria Market, full of smells and sights and sounds. It is also bustling, but stools can be drawn up at a tapas bar, and a serve of grilled mussels wahed down with a glass of cava is a superior tonic!
