The wide and panoramic summit, characterized by a wooden lookout, can be reached by crossing an area of karst land in the process of scrubbing. From the terrace you can enjoy a splendid 360 ° view: from the Sanctuary of Monte Grisa to the church of Monrupino up to the Monte Nanos massif and the Vipava Valley.

Timavo River Springs
Highlight • River
The area of the springs, located in the municipality of Duino-Aurisina, has been an important place of worship since ancient times. The presence of a river that flowed from the earth had intrigued and frightened primitive populations. Diomedes, Hercules, Saturn, the Spes Augusta, Liber Augustus and the god Temavus were venerated.
Virgil was so impressed by it that he mentioned it three times: Eclogue VIII, 6, Georgics, book III, 475 and Aeneid, book I, 244.
The Via Flavia passed through here and in the area of the mouth of the Timavo the amber road reached the Adriatic Sea, along which the precious fossil resin was imported from the Baltic since pre-Roman times.
In the 4th century, with the advent of Christianity, the first chapel was built, which, with subsequent modifications, became the basilica of San Giovanni in Tuba

Grotta Priamo
Highlight • Cave
In recent years the cavity, located a few meters from a wide path that was passable by vehicles, was used as a landfill. It was cleaned by the San Giusto Speleological Group of Trieste, which made it possible to visit it. This cavity is the first stop of Park 97, a Great War route inaugurated in the summer of 2017 in the Bosco Fornace di Prosecco.

Tips from the Community
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.

A place of peace with beautiful views, its size allows for undisturbed strolls. As one of the largest parks in Italy, it offers trees and plants from all over the world on an area of 22 hectares. Ferdinand Maximilian Joseph Maria of Austria was passionate about botany. It was he himself who designated the rocky outcrop as the spot where the park would be built. It was originally conceived as an experimental station for the reforestation and acclimatization of rare botanical species. Following a design by the Bohemian architect Anton Jelinek, the Cape of Grignano was leveled and covered with soil specially brought from Styria and Carinthia. Strolling through the park, you will notice two distinct areas: One is used as a forest and features paths, ponds, and pavilions. The sheltered area, on the other hand, is characterized by geometrically designed areas, greenhouses, and Italian-style gardens.

Beautiful panoramic views, stretching from Istria to the Carnic Alps, at least on a clear day. To the east, the Pleša, considered the southernmost mountain in the Eastern Alps, is clearly visible.

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.

In the area of the Risorgive del Timavo, where the Timavo river emerges from the vegetation, the medieval church of San Giovanni in Tuba stands suggestively with its late Gothic style.
