Callejón de San Cecilio leads to the Mirador San Nicolás, a lookout with unbeatable views of the Alhambra and Sierra Nevada. Come back here for sunset (you can't miss the trail then!). At any time of day take care: skilful, well-organised wallet-lifters and bag-snatchers operate here. Don't be put off – it is still a terrific atmosphere, with buskers and local students intermingling with camera-toting tourists.
