Picnic with live music? Why not! Enjoy lovely views, shade and life music. Go a bit around the building and find quieter places free from tourists. Come also by night (best after seeing the fountains or watch them from up here!)
If you are visiting MNAC and you get tired you can simply enjoy the views while sitting on the grass around the building and listening to live music. Also if you plan to visit this area you should also think about Anella Olimpica which is very close. I will not recommend you the Botanic Garden which is really small and not very interesting.
MNAC is free on Saturdays afternoons and every first Sunday of a month.
Tu-Su: 10:00-20:00
