I was trepidatious about booking this trip as there are a few options out there, but I am very happy indeed that I chose this company as it was very organised, extremely interesting, and superbly well coordinated.
The crew made sure that we were extremely happy, well fed, and entertained at all times, even though the natural beauty of the landscape required very little extras to be satisfied. Our guide, Raul, was very entertaining and informative.
The trek itself is quite arduous, though very achievable for most people. I can honestly say it was one of the best experiences of my life, and I'd highly recommend this trip to anyone.
