Side trips during a visit to the Macha Picchu Citadel in the Peruvian Andes. The Inca Trail goes deep into the mountains arriving to Macha Picchu from the town Agauas Calientes, and extending beyond Macha Picchu for many more miles. Most people, including me, stop walking the trail when you arrive at the Inca Bridge, with a few planks of wood spanning a precipice from which you would have a lethal fall.
Huayna Picchu overlooks Macha Picchu and is the mountain seen in the background in most scenic photos of the Citadel. Huayna Picchu has wet stone and well-known to be challenging to climb, with occasional wet "stairs of death" carved into the rock. We made it to the top (~9,000 feet high) and had breathtaking views of the Macha Picchu and the Andes.
