Iskar–Panega Geopark & Prohodna Cave
Геопарк Искър–Панега и пещера Проходна
The Iskar–Panega Geopark combines a turquoise karst river section with trails and viewpoints, while nearby Prohodna Cave is famous for its “Eyes of God” roof openings. Short paths follow the Zlatna Panega River between limestone walls, with interpretive panels along the route. Prohodna itself is a through‑cave, easily traversed on foot but muddy after rain.

Veliko Tarnovo
The former medieval capital is one of the country’s strongest city destinations, even beyond Tsarevets. Its steep streets, river bends, and layered history make it an indispensable national reference point.

Veliko Tarnovo & Tsarevets Fortress
Veliko Tarnovo cascades down steep ridges above the Yantra River, with Tsarevets fortress dominating a horseshoe meander. Restored walls trace the medieval Bulgarian capital, while a cobbled ascent leads to palace ruins and the Patriarchal church viewpoint. Evening sound‑and‑light shows periodically illuminate the hill, drawing both Bulgarians and international visitors.

Belogradchik Rocks & Kaleto Fortress
Sandstone and conglomerate towers ring the restored Kaleto fortress above Belogradchik, creating one of Bulgaria’s most surreal panoramas. Ottoman-era walls climb between red cliffs, with paths leading to multiple terraces over the town and western Balkan range. The site mixes easy viewpoints with short, steep stairways that can be slippery after rain.

Kom–Emine Trail: Western Stara Planina Section
The Kom–Emine route, Bulgaria’s classic long-distance trail, begins at Mount Kom near the Serbian border and follows the Balkan ridge east to Cape Emine. Western stretches above Berkovitsa and Petrohan offer grassy summits, wind‑exposed ridgelines and basic huts. Local hikers often sample one‑ or two‑day sections rather than committing to the full 20–25 day traverse.
