May 4, 2026, Giordano Cottur Cycle Path

The Giordano Cottur cycle path is a route of about 12 kilometers that connects the center of Trieste to the Karst plateau, following the track of the disused Trieste-Kozina railway. Starting from the San Giacomo district, the route climbs with a constant and gentle gradient, crossing tunnels dug into the rock and spectacular viaducts that offer dizzying views of the Val Rosandra. Along the way, the landscape quickly changes from an urban environment to Mediterranean scrub, until it reaches the white limestone of the Karst. After passing the Draga Sant’Elia station, the trail crosses the Slovenian border, becoming a symbol of cross-border union. It is a much-loved green artery for leisure, capable of blending industrial archaeology and wild nature.

May 4, 2026, Val Rosandra

Located behind Trieste, Val Rosandra is a unique nature reserve where the homonymous stream has carved the only deeply incised valley of the Trieste Karst. The landscape is dominated by rugged limestone cliffs, white scree slopes, and vegetation that blends Mediterranean and continental species. Famous for its 36-meter-high waterfall, the valley is a sanctuary of biodiversity and history: it hosts the remains of a 1st-century AD Roman aqueduct and the ancient church of Santa Maria in Siaris. A prime location for Trieste's mountaineering, its cliffs were the school of Emilio Comici. Between arduous trails and views of the Gulf, Val Rosandra represents a concentration of wild nature and millennia-old testimonies, suspended between the Karst plateau and the Adriatic Sea.
