The natural Reserve of Val Rosandra-Dolina Glinščice
From a geomorphological point of view, the Rosandra Valley Reserve - Dolina Glinščice is made up of a deep gorge that cuts through the Karst plateau in a north-west - south-east direction, where the landscape of cliffs, scree, vertical walls and the gorge of the Rosandra - Glinščica stream, the only surface watercourse in the Italian Karst, offers a unique landscape near the city of Trieste.
The area is characterised by a marked asymmetry of slopes: on the one side the scree dominates, on the other side forests alternate with vertical walls. On some of the flatter areas there are karst heathlands (kraška gmajna), and near the stream there is vegetation more typical of wetter areas.
Thanks to its rich natural heritage, Val Rosandra-Dolina Glinščice has always been a destination for hikers, climbers, cavers and researchers. But it is above all the locals who visit it and live in it, who have contributed to the preservation of the natural and cultural heritage of this area, finding in it a refuge in nature and a resource for local activities.
The Val Rosandra - Dolina Glinščice Reserve is officially a protected area; it is a Regional Nature Reserve, established by the Regional Law 30.9.1996 no. 42, article. 52, it is included in the National List of Italian Protected Areas and is part of the Natura 2000 network. Since 2006 the Reserve has been managed by the Municipality of San Dorligo della Valle - Občina Dolina.
