Travel expert recommends exploring Iguaza Falls and Patagonia
People planning adventure holidays in South America should visit Argentina and Brazil, as they are home to some stunning "natural wonders", according to an expert on travel.
Heather Carswell, a spokeswoman for the guidebook publishing company Lonely Planet, noted three major sites in the two countries that are well worth visiting.
"Iguazu Falls on the Brazilian border is one of South America's greatest natural wonders and well worth [visiting].
"Also not to be missed are the Patagonian glaciers and towns in the mountainous west of [Argentina]," Ms Carswell noted.
People planning to explore South America may find that a great place to start is Buenos Aires, which is "a good hub for travelling onwards", according to the travel expert.
From here, people on adventure holidays can visit Curitiba and the Costa Verde and eventually Rio de Janeiro.
Lonely Planet annually sells more than six million books and also operates TV programs, podcasts and websites.
