After a breathtaking ride over the snowy peaks of the Andes Mountains, the turboprop plane descended from thin air to the thick, humid atmosphere of the jungle. Below us, a muddy river coiled through vibrant verdant forest—until the thick tangle of trees gave way to the dull brown patchwork quilt of agriculture. Ahead lay the airport runway of the city of Coca, near where another river merged and created an even wider winding flow.
Beneath me was the Amazon basin, but still a long way from Brazil. It takes a lot of water to feed the world’s largest river by volume. Ecuador is home to a mere 2 percent of the big river’s source waters, but the three nights I spent at an eco-lodge along the Napo River would be unforgettable. But first I had another two hours of travel on a long and low river launch before I could check in.
