I recommend the Salkantay trek, as an experience that everyone should experience in their lifetime - incredible landscape.
It was my first time to Peru and I don't speak Spanish - as a result I was often confused about logistics and unclear about what was an "add-on" to the experience and what was included. Hindsight 20/20 I wish I would've done more research about how to deal with altitude sickness, the details about the trek, and the differences about what other options were out there.
This trip was defiantly more Glamping than expected- hiking from base camp to base camp with flush toilets and showers. A great experience but I wish my expectations were better managed.
