Wetlands and open grassy plains along the Yacuma River, flooded part of the year, making it one of South America's easiest places to watch wildlife, as animals gather by the river in open country rather than dense forest. Tours set out by boat on the calm river beneath overhanging trees, showing caimans on the banks, capybaras, the world's largest rodents, pink river dolphins, turtles, little squirrel monkeys in the branches and hundreds of birds such as herons, storks and woodpeckers. Tours usually include a sunset boat outing, a night trip with torches to spot caiman eyes, a walk on the plains looking for anacondas, and piranha fishing. They normally take three days from Rurrenabaque with nights in riverside lodges. Choose a company that respects the animals and does not feed or handle them, and don't swim in the river with the caimans. The lowlands are hot, humid and full of mosquitoes, so bring repellent and light long clothes, and ask your doctor about yellow fever vaccination. Bolivia is under a state of emergency with protests and road blockades, so check road conditions and your government's travel advice before the trip.

Madidi's jungle is for plants and birds under dense cover; the pampas show animals in the open by the river, like dolphins, caimans and capybaras.
