Amazing trek, maybe the best trip of my life and I made many trips. Really hard work out, so be prepared to push your boundaries. The nice crew was taking really good care of everybody. Feels like family. I recommend everyone to take this beautiful journey with Inca Trail Reservations - Salkantay.org. And make sure you have warm clothes with you for the trek through the mountains.
When you descend you need your shorts and a t-shirt. I also recommend the zip-lining option. It's a real adventure with beautiful views. If you can not make the big trip up the mountain, you can rent a horse. Really good option if your feet feel tired. If I can do it, you can do it. I made it, and I am so proud of it. Worth every penny. Amazing track. By the way, I am 54 years young !
