Words can not adequately describe the nature beauty this trip lets you see. It's a must if you like any sort of natural beauty.
You will find yourself over eating and hiking like a king after working your butt off from hiking. I would highly recommend following best practices. Overall, I would never trade this experience for anything and the porters where fun company.
Please be warned that the altitude difficulties are very real and one must prepare adequately. Also, agua de Florida is great and is a must use. Also, please be aware of the season you are hiking Machu. I went during the winter/ wet season and paid for it in some manners by limited photos.
However, it also lead to some more breath taking photos that you would not have otherwise. Hence, this trip is a must and this company is a safe choose to have the hike of a lifetime.
