In Figueres there are a couple more museums you may want to visit.
The Museu del Joguet, where you can see more than 5,000 toys, old and new. This is a good museum for families with kids. Some of the toys belonged to Salvador Dalí himself!
The Museu Empordà displays works from the Greek times through the 20th century. Only worth visiting if you have plenty of time.
