|After the heat of Lima, Huaraz was a bit of a shock! At over 3000m, it's a bit chilly! We came to acclimatize to the altitude (and temperature!), and get ourselves sorted to go trekking in the Cordillera Blanca - which means we spent a couple of days lazing about, catching colds, and getting headaches going over high-altitude passes to visit a beautiful mountain-reflecting lake, and the architectural site at Chavin. 'Chavín de Huantar' contains ruins and artifacts originally constructed by the Chavin, our earliest pre-Inca culture yet - it was built in around 900 BC(!), and contains amazing underground labyrinth-like tunnels with sticky-out stones where they apparently hung prisoners to be eaten by vampire bats!! On a clear day (and we did have one!), you can see the snow-capped mountains that surround Huaraz - it's beautiful then, and it was a good introduction to the area for us.
