You step off the minivan at the edge of Komstitsa and the ground underfoot changes from pavement to limestone dust — a fossil-studded surface that remembers a time when this ridge lay beneath a warm, shallow sea.
The trail makes a loose loop around Kaleto peak, tracking old dirt roads and low ridgelines where belemnites and ammonites are exposed like the pages of a stone book. The surrounding karst slopes were laid down in the Triassic and Jurassic; uplift and erosion have since pared away younger layers, leaving a landscape that reads like a field guide to deep time. Thracian camps and Roman roads once threaded these same rises; during the Bulgarian Revival the nearby village grew into a local craft and dairy center, and traces of that human history still show in stone foundations and pasture walls.
Expect open panoramas interrupted by thorny scrub and shelly outcrops; the air can be dry and sun-pressed, but winds across the ridge push heat and dust along like impatient hands. The route is non-technical but long — a full-day walk that rewards patience with close fossil viewing and uncluttered views of the Sofia plain.
Practical guidance: start early to avoid midday sun, carry 2–3 liters of water and a sun hat, and wear sturdy shoes for uneven limestone and loose scree. Photography is best in low-angle morning light when fossil relief casts shadows. Respect exposed fossils — take photos, not specimens — and follow your guide on narrow sections. With moderate pacing, the circuit fits hikers of most fitness levels and makes a good geology-focused day trip from Sofia.
easy.
6–8 hours.
Suitable for hikers with basic endurance who can handle a full day of walking on uneven dirt and limestone surfaces.

Komstitsa sits on ancient routes used by Thracian tribes and Romans; the exposed Jurassic limestones hold belemnites and ammonites that mark the region’s marine past.
The area’s karst outcrops are geologically sensitive; visitors should stick to paths, avoid sampling fossils, and carry out all trash to limit erosion and disturbance.
