Pantanal, Brazil

The Pantanal, recognized as the world's largest tropical wetland, spans an area estimated between 140,000 and 195,000 square kilometers across Brazil, Bolivia, and Paraguay. It boasts the highest density of jaguars on the planet, with studies indicating as many as 12.4 jaguars per 100 square kilometers in protected areas. This makes it an exceptional destination for jaguar sightings, particularly during boat tours along the Paraguay River between June and October. The Pantanal is also home to giant otters, which can reach lengths of up to 1.8 meters, and a rich diversity of birdlife, with over 650 species recorded. This includes numerous aquatic and marsh birds, making it a birdwatching paradise. The open landscape of this floodplain environment often makes wildlife spotting easier compared to denser habitats like the Amazon.
