A Ramsar site is a wetland site designated to be of international importance under the Ramsar Convention. In Ushuaia, the Vinciguerra Glacier and peatlands Ramsar Site is located in the Andorra Valley and it has a total surface of 2.760 hectares. This site has 11 types of wetlands, among them are the Vinciguerra Glacier, which includes lagoons, permafrost environments and high altitude wetlands, and the Andorra Valley peat bog, which includes elements such as Sphagnum. The valley slopes are dominated by a Nothofagus forest which in turn contains other varieties of wetlands.

In addition to its international importance, the site is of great environmental value locally, as the peatlands protect the most important source of drinking water for Ushuaia, the Arroyo Grande. This not only contributes to water quality, but also regulates flooding.

In this Ramsar site there are many marked trails to walk and visit places like the Vinciguerra Glacier, the Laguna de los Témpanos, the Laguna Encantada, or the Mirador Piedras Panorámicas. It should be noted that is not allowed to make fire in any of these places.
