This project is looking for volunteers to assist locals in building one of the worlds best ecological treks. It will pass by several waterfalls, one of them being 3 times as high as the Eiffel Tower. Each volunteer has the option of being assigned a team of local Andean Natives who will do the heavy work of excavating and constructing the path, or lighter duties such as planting indigenous flora, teaching English in local schools, or other community support. This is a great opportunity for volunteers to assist and support the local community in becoming the caretakers and sole benefactors of this natural wonder.

Volunteers pay £12 per day to hire their own team of village workers. Lodging in the area costs around £4.50 per day plus food. An all-inclusive package is available if you want the project leader to make all the arrangements for your stay.
