Huaraz is a city in Ancash. It’s 3052 meters above sea level and a place I recommend spending at least a week: two or three days to acclimatize without doing demanding activities and the rest to venture in the beauty of nature. In the search for attractions (I love mountains and hiking)), I found a small company that offered tours at a good price (you will realize that Peru is a very cheap country, at least much cheaper than Costa Rica and for some activities, a guide is a must).
