Nasca...not as great as I´d thought it would be. Didn´t do the flight as was told it was not really worth it, and after a night bus from hell really didn´t want to get up that early especially for that privellage.
On our way to Ica we stopped at the watch tower to view two of the lines, the tree and the hand. The ground where the lines are can no longer be walked or driven on, but this only came into effect about 30 years ago, so there are lots of other tracks across many of the drawings.
They say that the lines were used for astronomical calendars but no one really knows. They were built before the Incas...it is strange thinking about how they could have got them so precise.
