The Dunas de San Cosme y San Damián, a flooded sand dune area, offers a unique landscape in Paraguay. Accessibility might be limited due to the inundation, and inquiring about current water levels is advisable before visiting. Solo exploration is possible, but a local guide can enhance the experience by providing information on the ecosystem and navigation through the area. Seasonal changes, especially rainfall, significantly impact the landscape and accessibility. Costs are relatively low, mainly encompassing transportation and potential guide fees. A typical visit may last for a few hours to a full day, depending on the activities planned, such as birdwatching or simply enjoying the scenery.
