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.

The cave is closed indefinitely due to major damage. Nevertheless, it's worth a visit because of the surrounding forest botanical garden, which offers a good overview of the tree species planted in the forest and the (natural) vegetation on the ground.

Napoleon's Oak. The name seems to derive from the fact that it was used by French soldiers to tie their horses to (which is at least plausible, considering that the tree is certainly centuries old). According to another legend, less plausible, Napoleon Bonaparte himself stopped to rest in its shade (but in the last century throughout Europe there was an inflation of houses, hotels, castles and convents in which it was claimed that Napoleon would have stopped to sleep... a number so high as to be unlikely, and probably the result above all only of popular rumours).
