🇦🇷 Argentina
Gran Chaco, Argentina 614 spp. recorded
El Impenetrable National Park is a tropical savanna in the Gran Chaco of Argentina, a mosaic of dense dry forest, palm‑groves and seasonally flooded lowlands. The landscape supports a mix of towering quebracho trees and open grass patches that give way to water‑filled depressions where the broad‑snouted caiman basks.

What visitors say
The Impenetrable also allowed us to marvel at the Chaco fauna: We spotted peccaries, cottontail rabbits, and brown deer, and, at the most exciting moment of the trip, a tapir that calmly let itself be observed, reminding us that there are still places where these large mammals live free and safe.
It is possible there are or have been other jaguars we haven’t seen at this bookend of the species’ range.
“My first trip to El Impenetrable was like traveling back in time because it still had the flora and fauna we’re losing elsewhere,” recalls Marisi López, regional coordinator of parks and tourism at Rewilding Argentina.
