From Kastav near Matulji, there is a marked path leading northwards towards Klana. The route leads across the Zvirić ranch, next to the cave Šparožna jama, across Mačkov vrh and Skalnica to Klana. The tour takes 5 hours of hiking. The settlement of Klana is a portal into the mountainous world of the so-called Grobnik Alps. From Studena, which is located one kilometer southeast of Matulji, a marked path first leads us to Limes (remains of a fortified Roman border), without major climbs. The path then gradually starts getting more and more steep, taking us towards Obruč. The markings of the Rijeka Hiking Tour (Riječka obilaznica, RO) leading towards Obruč begin on the road between Studena and Klana, 1 kilometer away from Klana and 200 meters away from the church of St. Nicholas. As we reach the hay meadow Ravno along the path, to the left we can see the remains of the Roman wall (Limes) from the 3rd and the 4th century (596 m.a.s.l.). After Limes, the path branches. To the left, there is a direct climb to the peak of Obruč. To the right, we see a trail taking us to the area of Planina and to the mountain pass Vrh Planine. Once there, we come across the descending markings from Obruč to our left, and there is a path leading to Podkilavac to our right. The climb from Studena to Obruč takes approximately 4 hours. In the area of Obruč (1 hour and a half of hiking from the peak), there is a nicely decorated mountain lodge Hahlić.
