I don't think there are words in any language that can sum up Machu Picchu. To say it is a World Wonder doesn't do it justice - it stands alone.
For three days we explored the Inca ruins and the surrounding valley and at every turn were left breathless by what was in front of us (and the altitude).
Machu Picchu became very special to us - partly for it's own beauty, because it was a major bucket list item we crossed off, but also because the day we first saw it was my father's birthday.
Other than to say that if it isn't on your 'To-Do' list it should be, I think I should let the pictures speak for themselves.
