Prior to jumping on the ship in Buenos Aires, visit Iguazú Falls, which spans the border of Argentina and Brazil in a large national park and rainforest. The semicircular waterfall is the pulse of the site.You may even spy capuchin monkeys along the way.

Parati is a nature-lover’s paradise, offering views of both the coastline and mountains. Take a trip to Saco de Mamanguá, a gorgeous fjord-shaped inlet that cuts into the mountains just southeast of the town. Or opt for a boat tour and hike to the dramatic Pão de Açúcar do Mamanguá peak for views of the bay and islands below.

After departing the ship in Rio de Janeiro, visit the Tijuca Forest, the world’s largest urban forest. Navigate dozens of waterfalls, viewpoints, hikes, peaks, monuments, and incredible biodiversity. It’s also home to one of the world’s most famous monuments, Christ the Redeemer. Perched on Corcovado mountain, take the small train or trek up the mountain and explore the monument.
