The island's circular shape is near-perfect, measuring approximately 120 meters in diameter.
It floats within a circular channel of water that is essentially the same diameter as the island itself.
The core of the island is firm enough to support vegetation but is primarily composed of matted, buoyant aquatic life.
Its rotation is triggered by the shifting currents of the Paraná Delta marshland.
The site gained international attention after a production team accidentally discovered it while scouting locations for a film.
El Ojo Misterioso is a unique floating island located in the delta region of the Río Luján, notable for its nearly perfect circular shape and ability to rotate within its watery basin. The island, discovered by filmmaker Sergio Neuspiller, is composed of dense vegetation that rests on a layer of aquatic plants. It moves independently due to the interaction between the water current and the island's own buoyancy. The surrounding environment consists of marshy wetlands typical of the Paraná Delta ecosystem. Its existence has been subject to various geological studies to explain the precise circular geometry of the site.

Wear waterproof footwear suitable for muddy, uneven marshland terrain.
Use insect repellent, as the delta ecosystem is highly active with mosquitoes and other insects.
Bring binoculars for better observation of the island's movement from the perimeter.
Attempting to access the island without a guided local boat service, as the surrounding marsh is prone to quicksand-like mud.
Access is highly dependent on water levels; the site may be inaccessible following heavy rains or storms.
Stay on marked paths or observation points to protect the fragile wetland soil; do not attempt to board the island.
