About an hour away from Loutraki, just opposite the Alkyonides Islands, there is one of the most beautiful natural monuments in the area. It is a rocky formation, a natural arch above the turquoise waters of the sea. The crystal clear blue waters in combination with the ornate rocks, create a heavenly landscape.
The "Cave of the Seal" as the locals call it is one of the most untouched parts of the Corinthian Gulf as it remained unknown for years, due to the fact that access to it is difficult. The point is accessible by boat or via a pine-covered path.
