The trip is incredible. The scenery varies every day and you'll ride on all possible terrains: sand, rock, gravel, tarmac and every day offers a lot of fun. The landscape of the Moon Valley in Chile is surreal and the Tatio geyser excursion is a stunning experience. Chile and Argentina are lovely countries; the areas visited still haven't been reached by mass tourism and you barely see any other tourists while travelling.
As my wife mentioned, we made this tour to Argentina and absolutely loved it. The tour is great because it combines three destinations that we were willing to visit this time in Argentina which were Buenos Aires city, Iguazu Falls and the northern region of the country, which are all very different from each other. Great experience!
