Dawn breaks over the Blue Stones and a line of pale limestone cliffs catches the light—rock faces that once lay under a prehistoric sea now stand like a ringed amphitheater daring you to climb. The Halkata, “The Ring,” is a rounded rock aperture on a promontory above forested slopes; the first steps into the Blue Stones Nature Park feel like crossing into a different rhythm where wind and birds keep the tempo.
