Less than 20 minutes southeast from Trieste is Val Rosandra Natural Preserve covering a surface area of about 746 hectares with two geologically very different sides and plenty of stunning panoramas over the Gulf of Trieste. The 120ft waterfall and ruins of a Roman aqueduct also adorn the footpaths through the valley leading toward the Slovenian border. Not far away lies the Škocjan Caves Regional Park, a system with its unique natural values — renowned for its exceptional archaeological finds, pioneering explorations of the Karst underground, and rich natural and cultural heritage. Lipica, a nearby village, is one of the main tourist centers of the Karst region known as the origin of the beautiful white Lipizzan horses!
