The Dunes of San Cosme and Damián are one of those paradisiacal places that you can only find in Paraguay. Many years ago, they were simply dunes on top of a hill on the Paraná, but with the rise of the river due to the reservoir of the Yacyretá Dam, these have started forming an isolated island of white sands, nestled in the middle of the water.

To reach the dunes, you need to arrange for transport via boat or ferry. Keep in mind to carry bags for your waste, sunscreen, equipment for shade and to sit, since they are deserted islands in the middle of nowhere, but precisely that isolation gives it the paradisiacal touch and tranquility, making its beaches with crystal clear waters are the most envied in the country.

Unfortunately, the dunes are at risk of disappearance due to the rising levels of the water of the Paraná River.
