You push away from the trailhead and the pines close behind you like a living wall; the singletrack immediately tilts, and the Karandila ridgelines open to slabby rock and scrub where wind has carved the stone. Blue Stones Nature Park (Sinite Kamani) sits a short ride south of Sliven, Bulgaria — a compact massif of granite outcrops, exposed ridges and steep, technical descents that both dare and reward riders.
