Sturdy hiking boots are a must on this rugged terrain and make sure they are water proof. Likewise, you'll need good rain gear and lots of layers to keep dry and warm. Weather in the Andes is highly unpredictable so best to come prepared for anything.
A wide angle lens is great for getting the big picture of the vast Andean landscape and a zoom gets you some great shots of the wildlife, even when it's not so wild, like our alpaca friend.
If you are planning on doing the Vicuņa Trail you'll need a good tent, one that doesn't leak and is resistant to wind as this is one windy and wet place when it wants to be. There are no hostels or rooms of any kind on the trail and you will be back country camping.
Bring your fuel from Quito, it's likely the only place you'll find a good selection and bring your food from either there or a neighboring big town like Ambato or Riobamba.
