The best hike in the world for me personally was the Huayhuash Circuit,
We did rent a cook tent and hire a mule driver, but decided on our route independently.
Huayhuash is dangerous. Hikers have died there. This is arguably the best hike in the world but is appropriate only for robust, experienced high altitude trekkers.
The greatest danger is altitude sickness. We hired horses instead of mules so we could evacuate by horse, if necessary. Smart trekkers do some acclimatization treks out of Huaraz before catching the bus to Huayhuash.
