It is an amazing drive, and NO it is not all flat & boring. There are massive hills and valleys that we have to wind up and down. Before we leave the beachside town of Arica we do a detour to see some geoglyphs on the hills. These are huge pictures etched on the hills, probably used as route markers. Actually we find heaps more later on in our drive.
There are also 100's of mines in the desert. (They are the reason Chile went to war with Peru & Bolivia - Chile wanted the mineral wealth). Anyway we visited a fantastic old nitrate mine & town called Humberstone.
Another amazing site was the city of Iquique set right on the waterfront below huge desert cliffs. There was some very expensive beachfront real estate here, right in the middle of nowhere. Of course there have been heaps of gorgeous beaches and lots of busy ports shipping out Chile's wealth. Some of these have been a bit rough and downright ramshackle, but great to pass through.
Then of course we had to stop at Mano del Desierts (the huge granite hand) for a photo shoot- we now have a new brochere picture for SLR Motorhomes.
Finding camp spots in GR2 has been a breeze. Either at the beach or in desert we just find a quiet spot and drive off road.
