In the dunes of the narrowest central point of the island of Chryssi, we find one of the most significant forests of coastal juniper (known as cedar) in Greece. In other parts of the island, like the west and east, we also find vegetation with the principal plant being Juniperus phoenicea.

The juniper forest occupies around 350,000 square meters and consists of juniper trees which are on average 200 years old. Some trees exceed 10 meters in height and are over 300 years old. The coastal juniper holds the sand with its huge roots. Crossing the forest is officially forbidden, so the zones where you can walk have been delimited with a rope. The spread of pine trees, existing in some forest areas, may also be considered a threat.
