Do the 3 day hike/camping up there, was a couple of gobby young ones in the group but they were soon puffed out so got less annoying! If you ever down that way stay in the Sacred Valley, stunning.
Surprised Rio gets a mention, found it a large ****ehole. Beaches were not even that great.
Hard to pinpoint a place in all our travels, I think sat on top of Mount Kinabalu in the fresh early morning taking in the views is one of my most recent favourite ones, killed my legs though getting back down.
