Where is the high country? Head south a little, and cross some braided rivers. Head inland until the land curves up, and the grass flats start turning into scree slopes. If there isn't some bog and some spaniards, you're in the wrong place. But when you're there, you'll know it. Glacial mountains, steep sided valleys, and people trying to look fierce.
Looking at these photos reminds me of how many people there are here in Switzerland. Nowhere can you go where there is this much empty space. Lovely open terrain where it would take a fool to get lost. Just move your legs and walk till the sun goes down. Wake up and do it again.
