Islets of Porto Santo

The Islets of Porto Santo are six limestone formations surrounding Porto Santo Island within the Madeira archipelago, separated by narrow channels of seawater. They support rocky coastal habitats with low vegetation and serve as nesting grounds for specialized seabirds adapted to these isolated rocky environments.

The islets received official protection status in 1995 as a Natura 2000 area, marking a turning point in conservation efforts for the Madeira region. This designation acknowledged their ecological importance for local marine ecosystems and their role in preserving rare species.

The islets network forms an essential part of Portuguese marine conservation efforts, reflecting national commitment to ecological preservation.

These sites are only accessible from the water and are best visited during calm sea conditions. Access requires a boat or organized tour, and visitors should maintain distance to avoid disturbing nesting birds during breeding season.

These formations harbor two land snail species found nowhere else on Earth, making them crucial habitats for global biodiversity. Their remote rocky setting and isolation have allowed these distinctive organisms to evolve over time.
