The Salkantay Trek is one of the best adventure alternatives. It will allow you to visit Machu Picchu in 5 days and 4 nights on a 73 kilometer (45.3 miles) hike. Of course, you should be in a good physical condition since the route is relatively longer and you could even say that the road is somewhat more rugged. However, there are several points in favor of this Inca Trail passing Salkantay.
One of them is that it is definitely an even more authentic adventure than the classic Inca Trail. You will explore a remote road and climb up one of the highest peaks of Peru: the Salkantay mountain top. Then, descend through the cloud forest near the jungle. Another point in favor of this trail is that you won’t find many people on it compared to other treks to Machu Picchu. So you will travel with a small group with a maximum of 8 people and the road won’t be crowded.
