1. A single journey on Barcelona's metro/bus network costs €1.25. As you'll need to use some mode of transport at least three times, rather than paying for single journeys, buy a T-10 (ten journeys) for €6.90. It gives ten journeys for less than the price of six.

2. This watershow at the fountain in Plaza Carles Buïgas in Montjuic is truly unforgettable. The display of music, water acrobatics and lights generates over 50 kinds of shades and hues, to classical, pop and other types of music. Spring & summer: Thurs-Sun 9pm-11pm; Autumn & Winter: Fri & Sat 7pm-9pm.

3. Found in the heart of the Barri Gotic, this cathedral was built between the 13th and 15th centuries, although the spire and façade weren't added until the late 19th century. While the interior of the cathedral is breathtaking, make sure to visit Capella de Lepanto in the same grounds where you'll find a pond of white geese. Open daily from 8.30am-1.30pm & 4pm-7.30pm; admission free.

4. One of Europe's most famous streets, there is something going on along the Ramblas twenty four hours a day. Pet stalls, flower sellers, human statues, buskers, magicians and other street entertainers make it one of the liveliest streets in the world.

5. Located in the Gracia part of town, Parc Guell is Barcelona's most famous park. It has several trademark landmarks, such as the dragon at the entrance, the serpentine bench on the upper terrace, the Dorici columns that support this, and much more. It also boasts breathtaking views of the city. Open daily 10am-7pm; admission free.
