This museum is certainly worth a visit and a bonus is you get a great view both from the terrace of the museum and from Montjuic park. It is not expensive, the collection of Miró's paintings and sculptures is fantastic, and it is not an overwhelming museum (meaning in less than 2 hours you can cover a great deal). In addition, you also get to view the work of other contemporary artists influenced by Miró's work. I was able to get a free one hour group tour that the museum offers. Make sure to ask about this because it is worth it. They take you to Miró's most celebrated works, and you get to discuss some of the paintings, the context surrounding his works, his relationship with other artists, etc..
