    Hiking

    Grda Jama is a large cave beneath Snežnik. It lies right next to the forest road. There's not much information about it, only that it's 240 meters long and 191 meters deep. It was discovered in 1950. Access from the road is easy, but the last twelve meters to the cave entrance are dangerous. The entrance drops vertically, and there's not much to see from above. Access is not possible without equipment!
