In addition to Trška gora, the Gradec Nordic trail is the most difficult route, since it has the highest climb. The trail takes you around the Hom hill; you will cross a century-old footbridge over the Radulja and see the ruins of the Gradec Roman military fortress from the 5th and 6th centuries. The foundations of a Christian basilica are still visible behind the reconstructed fortifications. The mill in Hom offers a pleasant spot for resting and having a snack, then the trail continues to Klevevž in the Radulja valley, which is described in trail 8.
