Travel to the Pantanal and southern Amazon where wildlife is at its most prolific, and aim for that most prized of sightings: a jaguar. Encontro das Aguas State Park near the remote outpost of Porto Jofre offers the best chance in South America of glimpsing these creatures in the wild. As with some other big-ticket wildlife experiences there is no guarantee of seeing jaguars but the excited accounts of sightings suggest that, for most, it is well worth the time, expense and hardship.
You also spend time at a lodge in northern Pantanal and also at one of the best wildlife-spotting locations of all, Cristalino Reserve on the fringes of Amazonia. The Pantanal’s open area of swampy grasslands, rivers and lagoons leaves fauna exposed to view. You might observe regiments of alligators, and flocks of thousands of roseate spoonbills, ibis, macaws and giant storks. In contrast, the area around your lodge in Alta Floresta has undisturbed primary rainforest hosting an enormous variety of mammals, reptiles and birds.
