My boyfriend and I went on the Salkantay trek (5 days and 4 nights) and we can really recommend it ! The nature was absolutely beautiful and everything was great planned. The food was great and people there were taking care of all you needed. You can bring 8 kilos that is carried by horse, so you only need to carry your backpack. Our guide was very informative. He told a lot of interesting things about the Incas and showed us some Inca Trail s as well. If you would like a trek with beautiful nature the Salkantay trek is the one.
