This 15 km walking trail is more demanding and offers wonderful views of Kvarner Bay, the mountains of Gorski Kotar, and the Kastav and Grobnik areas, especially from the limestone cliffs at the peak of Lončeva Griža, 506 m above sea level (griža means a pile of rocks). This vantage point also features interpretation boards in Chakavian, Croatian and English languages with information on the former quarry at Lončeva Griža, where boulders were extracted in the past. A smaller quarry located above the village of Skvažići was used for the needs of the village and its surrounding areas. An exhibition of old stone carving and cutting tools on the rock of the old quarry provides information on the customs of the Halubje area.
