Hiking in the Carso

High above Trieste’s coastline is a narrow ribbon of jagged rocks eroded by rain and wind, plunging fearlessly into the sea. Called “carso” in Italian, this landscape of limestone and dolomite conceals an underground world of vast caverns and grottoes, carved by the waters of the Timavo River, which runs below ground for much of its course from Slovenia to the Adriatic Sea. Above ground on the plateau lie acres of evergreen forests and flower-strewn ravines. The land is peppered with large sinkholes, called “doline,” that have been caused by collapsed cave vaults. Here, the warm sea breeze meets the chilling, northeasterly bora wind, producing a convergence of Mediterranean and Alpine climates. Oak and spruce mingle with citrus and olive trees, while the landscape is blanketed with vineyards. Only one body of water flows above the plateau—the Rosandra Stream. Slicing through the deep gorge of the Val Rosandra near the Carso’s eastern border, these waters once supplied the ancient Roman colony of Tergeste via a seven-mile-long aqueduct.

The Park Val Rosandra is an 1800-acre nature reserve located just southeast of Trieste. The park’s hiking paths offer visitors frequent breathtaking vistas, including a 118-foot waterfall, the ruins of the Roman aqueduct, and a stunning panorama of the gulf of Trieste in the distance. To reach the park, take bus #40 or 41 from Trieste to the town of Bagnoli, where you will find the park’s entrance.
