Five thousand miles: that’s how much ground Lindblad Expeditions, the official outfitter of National Geographic, will cover on its 38-day journey down the eastern coast of South America, from the island of Trinidad to Buenos Aires, Argentina. This Latinophile’s fantasy trip, based off a 365-foot luxury expedition ship, has it all: empty beaches, the Amazon, wildlife viewing, and nightlife in Rio. Perks include swimming amid spinner dolphins in Brazil’s Unesco World Heritage site Fernando de Noronha archipelago, a flight over Guyana’s 822-foot Kaieteur Falls, and downtime to explore deserted islands. An A-list of experts will be on board, including former Colombian president César Gaviria and author Wade Davis, who spent years in the Amazon researching plants. From $34,730.
