Hiontalas

Hiontalas is a small, uninhabited island located in the Aegean Sea, approximately 5 kilometers off the coast of the island of Euboea in Greece. Geographically, it is part of the Sporades island group, though it is the southernmost and westernmost of the archipelago. The island is characterized by its rugged terrain, with rocky shores and sparse vegetation. Its size is roughly 1 square kilometer, and it reaches a modest elevation of around 50 meters.

The island has no permanent human settlement, and its primary significance is ecological. It serves as a breeding ground and resting point for various bird species, particularly migratory seabirds. The surrounding waters are also home to a diverse marine ecosystem, supporting a range of fish and invertebrate life. Due to its isolation and lack of development, Hiontalas retains a relatively pristine natural environment. Access to the island is typically by private boat, and it is not a tourist destination. Its geological composition is primarily sedimentary rock, typical of the region.
