Trekking is the major activity in the Machu Picchu area --  with the Inca Trail being the highlight. With routes that take either four or two days, choosing to hike is not a decision to take lightly. Given its exposed nature and high altitude, the trek can be quite strenuous at times, so be sure you are in good shape prior to hitting up the trail. However, if you just want to get a mini-feel of the trek, consider taking the hike from Agua Caliente up to the ruins rather than taking the shuttle bus. Note, however, that the trail is quite steep in places, and should be avoided during or after a rain, as the trail can become quite slippery.

Birdwatching is another great outdoors activity at Machu Picchu. There are over 400 species that are known to inhabit the Machu Picchu area. Some common sightings include birds of prey such as Aplomado falcons, mountain caracaras, and black-crested buzzard eagles. Other birds to mark off your life list  include quetzals, motmots, and guans.
