I first heard about Inca Trail Reservations by a friend that booked through them a few years back. They had nothing but positive things to say about the company and trek so I felt completely comfortable booking through them. I first must take a moment to complement Mabel who organized our 8 day trip (including the 4 day Inca Trail trek) via phone and email conversations. She handled everything professionally and I felt very informed on what to expect upon my arrival in Peru.
The trek itself was a lot of fun. There were plenty of spectacular views, though those didn't come without some effort... the second day was definitely challenging but the reward at the top was well worth it.
Our guide Carlos aka "King of the Mountains" was great. He ensured we got good camp sites, and that the vegetarians and lactose-intolerant among us got special food. The food was quite good by the way, and it amazed us that they were able to cook so many different things along the trek. He kept us informed and laughing along the way. And the final reward of Machu Picchu in the end seemed all that more special seeing as we spent 4 days hiking to it.
All in all, Inca Trail Reservations comes highly recommended.
