If you have time go to Retiro Park in Madrid, it seems like Madrid’s “Central Park”, and most of the museums are close by. There is also a Patrick Blanc Greenwall that is worth visiting http://www.treehugger.com/files/2008/03/madrid_gets_a_v.php near the Museo Prado. The Atocha Train Station is an amazing structure and it’s full of tropical plants–a great place to stop and have some coffee. Have fun!
