At the beginning of the activity, each person carries a backpack with the inflatable boat, which is light, compact and easy to transport, weighing a total of 6 kg. The trekking is low intensity and lasts 40 minutes. During the walk we crossed through forests and peat bogs, native species of Tierra del Fuego. We arrive at the Mariposa Lagoon where before entering the water we will inflate the boats, prepare ourselves and have an informative talk on safety and rowing technique. The second part of the adventure begins, one hour rowing down the river steering our boat letting ourselves go. We rest on a small river beach where the Laguna Esmeralda stream connects with the Olivia River, where we will have lunch surrounded by nature. In the second part of the route, we cross sections with native forest and bushes on the sides of the river, the landscape that surrounds us is beautiful and our mission is to take care of it, always bringing our waste and everything we see on the side of the river.
