The Salkantay Trek is one of the most popular alternative treks to Machu Picchu in Peru. Here is some information about the Salkantay Trek:

The Salkantay Trek is a challenging and rewarding trekking route that takes you through diverse landscapes, including snow-capped mountains, high-altitude passes, cloud forests, and remote Andean villages. It is named after the majestic Salkantay Mountain, which stands at an elevation of 6,271 meters (20,574 feet).

The typical Salkantay Trek starts in Mollepata, a small town located a few hours away from Cusco. The trek usually lasts for about 4 to 5 days, covering a distance of approximately 72 kilometers (45 miles). The route passes through breathtaking scenery and culminates at Machu Picchu.

The Salkantay Trek offers stunning natural beauty and cultural experiences. Highlights of the trek include crossing the Salkantay Pass at an altitude of 4,630 meters (15,190 feet), hiking through the beautiful Salkantay Valley, visiting the Humantay Lake, and exploring the Llactapata Inca ruins.

The Salkantay Trek is considered moderately difficult. It involves steep ascents and descents, high altitude, and varied terrain. It is recommended for those with a good level of physical fitness and some prior hiking experience. Acclimatization to the altitude is important to minimize the risk of altitude sickness.
