Being very close to the city and easily accessible, it is the best hike if there is no time to reach the carso. It has much to offer: a beautiful view of the city below and the gulf of Trieste, a nice and easy walk surrounded by nature and cliffs perfect for climbers.
Tram ride from Piazza Oberdan. Get off at Obelisco and walk along the Via Napoleonica as it is know locally. This is so worth the views. It is flat and a completely maintained path. Fabulous views over Trieste and a 6 kilometers (or thereabouts not quite sure as it did not feel difficult at all) you arrive in Prosecco and...
Starting from Opicina, this is a great, easy and famous walk. 4 km till Prosecco, you can decide whether to climb up on the 'Formaggino' aka Monte Grisa sanctuary. Enjoy the beautiful landscape on the sea and watch people climbing on the cliffs at the end of the path. To do!
It's a 5 km walk with beautiful scenery for almost the whole walk. There are places to rest with benches along the way. It's advisable to take the tram either going up or coming down (at least one way) which gives beautiful views down below. We were not so lucky since it was a hazy day.
Nice scenic road on the outskirts of Trieste. A 7 or 8 km long path from Opicina to Prosecco with spectacular views on the city of trieste and Adriatic Sea. On nice days you will meet plenty of people walking this path and enjoying nature. The only lowside of this path is lack of parking spaces at it's start.
