Perhaps Etna? I doubt the tourism board of Italy would like to advertise their country as "the home of Mordor" though!
Shire - England Rivendell - somewhere with lots of waterfalls (I like the film design) and in a deep valley Misty Mountains - NZ, or perhaps the Rockies, Andes ... Lorien - difficult one ... I'm not sure Fangorn - plenty of suitable forests in Europe
