I'm looking at options for a 2-day/1-night trek into the canyon from Arequipa. I am seeing quite a variety of price points, from $40USD (suggested by PeruHop) to $130 or $200 or more.
I can see where some trips include the 70 Sol park entrance fee and some don't; some have an extra meal, some include the cost for the hot springs, but none of that really adds up to that much extra.
The most expensive ones are clearly private, but when that is not obviously the case, they all seem to follow a similar itinerary and on the surface...they all kinda look the same.
If you've done this trek: Where are the hidden costs in the cheaper options? What benefits do we get for paying significantly more up front than the cheapo $40 options suggested by PeruHop?
