If you only have time to do one thing in Barcelona, you should see the sound and light show at the Font Magica of Montjuic.
It runs in the evenings from Thursday to Sunday in the summer and Friday to Saturday in the winter.
It is wonderful and it is free.
La Font Magica de Montjuic, Barcelona, Spain
Girona is a city that sits in the northeast corner of Spain, a conveniently short distance from bustling Barcelona. Although you could explore the cobblestoned historic Jewish quarter of town (Girona was a stronghold of Spanish Jews before the expulsion in 1492), admire the largest Gothic vault in Europe at the cathedral, and walk atop the former ramparts of the Roman walls of the city in a day, Girona deserves more of your time than a quick day trip.
