What to do and see in Val Rosandra

The Rosandra Valley is a land rich in history, and the earliest evidence dates back to prehistoric times. Fresh water and caves that provided shelter brought human presence from the earliest times. Added to this is the border with Slovenia and the proximity to the sea. Fortunately, human presence has always been temporary and has allowed this place to remain intact. Historic remains such as the mills, the Roman aqueduct, the church of Santa Maria in Siaris, the ice storage cisterns, and natural wonders, the waterfall, the caves, the Comici Capstone, the creek and puddles, and many others can be seen.

Paths and trails

Among many, they include:

  • the remains of the Roman aqueduct and ancient mill, both visible near the Premuda shelter;
  • the Friendship Trail, CAI 1-ex 13, which leads from the Premuda refuge to the viewpoint over the Rosandra stream waterfall and continues to the village of Bottazzo;
  • CAI 25 and CAI 13 trails, which lead first to the small church of Santa Maria in Siaris, then to the Cippo Comici;
  • CAI trail 39, which leads to Mount Karst and the Bukovec spring;
  • the Foresta d’Acqua trail, which connects Bagnoli to Basovizza, following the places of water: the stream, the ponds, the mills, the caves, and the Jazere di Draga Sant’Elia, cisterns that were used for ice production. The trail is 15 km long, which can be covered in about 5 hours.

Church of Santa Maria in Siaris

Deviating from CAI Trail 1 to CAI 25, one encounters the solitary little church of Santa Maria in Siaris, called, in the Slovenian language, Madonna on the rocks. The road is steeper and more challenging, but it is worth forking it to admire the lovely little church.
Continuing on, the road leads to the Comici cippus, an extraordinary viewpoint.

The Roman aqueduct

The Rosandra Valley has been frequented by man since the earliest times, and the remains of the 1st-century Roman aqueduct can still be seen, among other evidence.
The aqueduct measured 14 kilometers and reached the center of ancient Tergeste, which it supplied until the sixth or seventh century.
Today you can visit its remains near the beginning of CAI trail 1-ex 13.

The village of Bottazzo and the former border

For those who have walked the Friendship Trail to the waterfall of the Rosandra stream, it is recommended to continue to the village of Bottazzo, a very quaint little hamlet. Nearby are the remains of 4 ancient mills, while the old border with Slovenia is located in the village.

The vantage points

Following the Friendship Trail, CAI 1, we soon reach the viewpoint over the Rosandra stream waterfall, sparkling in the sun. Even more impressive, in the coldest winters, is to admire it frozen. Follow CAI trail 25 and later trail 13 to Cippo Comici, which offers a wonderful view of the valley and Mt. Stena. Climbing back up to the bike-pedestrian path, near the toll booth, you can admire the mountainous landscape and the small church of Santa Maria in Siaris. On CAI trail 15, you will come across the Moccò lookout; even from here, the view sweeps over the entire valley.

The bike path

Pedaling or walking along the Giordano Cottur bike/pedestrian path one is amazed to encounter railway stations and tunnels carved into the rock. This is because this particular bike path was set up on the route of the former Trieste-Erpelle Cosina railroad, which was dismantled in 1966.
Another reason to make it special is that starting from the center of the city of Trieste, the bike path leads directly into the unspoiled nature of the Rosandra Valley.
The trail is easy and suitable for everyone, and can also be walked as it has several accesses.
The bike path allows you to stop in Bottazzo or go as far as Kozina in Slovenia.
