There are a number of excellent trips through the Andean páramo (grassland) which features spectacular views of Ecuador's volcanic peaks. The most popular treks are the Trek de Condor, which passes the often cloud-shrouded Antisana, Sincholagua and Cotopaxi Volcano; and the Ingapirca Trek which takes you along an old Incan trail to Ecuador's most important Inca site. For the intrepid trekker there are several multi-day Andes-to-Amazon hikes that take you from the grassy plains of the high altitude páramo, through cloud forest, and finally to lowland rainforest. During your descent, as you pass from one ecosystem to another, you'll see dramatic changes in the flora and fauna while you are peeling off layer after layer of clothing. Rainforest hikes are also possible, but it’s a good idea to hire a local guide as it is easy to get lost. There are some great hikes from lodges along the Napo River, in the Amazon.
