Colonia del Sacramento
On the east bank of the Río de la Plata, 180km west of Montevideo, but only 50km from Buenos Aires by ferry, Colonia is an irresistibly picturesque town enshrined as a Unesco World Heritage site. Its Barrio Histórico, an irregular colonial-era nucleus of narrow cobbled streets, occupies a small peninsula jutting into the river.
Central Suriname Nature Reserve
One of the biggest swaths of Suriname's protected regions, covering 12% of Suriname's land area, this nature reserve covers 16,000 sq km and was established in 1998 with a US$1 million donation from Conservation International. Around 40% of Central Suriname Nature Reserve's plants and animals are found only in the Guianas.
What could be more mysterious than the discovery of an ancient abandoned city? Ciudad Perdida (literally 'Lost City') was lost around the time of the Spanish conquest and only 'discovered' again in the 1970s. Deep in the Sierra Nevada de Santa Marta mountains, it remains only accessible on foot by doing what is easily one of Colombia's most exciting and breathtaking hikes.
