So, is this about landscapes to admire or where we would like to live?
Rivendell for me - beautiful and comfortable and it has a library. When reading Tolkien's description of it in THE HOBBIT, I wanted to move there! A perfect place for a writer like me, or an artist ,and spending your evenings in the Hall of Fire and gazing out at those lovely waterfalls or hiking through the woods by day... Ithilien would be nice for a hike, though, especially Henneth Annun with its gorgeous curtain of water,and perhaps a yearly beach holiday in Dol Amroth (admittedly not described, but it's on the coast) or the Grey Havens.
