Trieste lies between the sea and the Karst. The landscape of its surroundings is unique – a land that lacks surface water, but is rich in caves and underground rivers. At a few kilometres from the city is the famous Grotta Gigante, one of the biggest natural cavities in the world, and in the middle of the Karst area is Val Rosandra, an amazing Nature Reserve valley.
Trekkers can enjoy the Karst and its magnificent landscapes in places such as the Rilke trail, which runs on high cliffs where people can enjoy a dramatic landscape of the Gulf, from Sistiana Bay to Duino Castle.
Close to Trieste is Muggia – a nice twon by the sea characterized by Venetian architecture. A stroll through its Calli will remind you of an ancient Venetian village. Moving on behind the Castle standing out on the twon’s small port, you can walk up the hill leading to the Muggia Vecchia (the Old twon), where you can admire the Basilica of S. Maria Assunta, the most ancient church in the Province.
