This trek is probably the hardest thing I have done in my 48 years, don't underestimate the effects of altitude !
The trek is well organised and very well run by our guides Paul and Marco. The walking starts early in the mornings 5.30 and is full days... Not for the softies who enjoy a lie in ! You see some great sites, the cold glacier pool was well worth the extra effort... Brave a dip if you dare !
Food could be a little more, but the cooks do an excellent job with the limited space and setting up in the middle of nowhere. Take plenty of money, at least 400 soles as there are no cash points.
