Beautiful circular trail on the Grubigstein
Take the Grubig I + II cable car to the top station. From there follow the wide path to the top station of the Gamsjet. Then follow the Hirtensteig to the right. Here you have a wonderful view of the Fernpass lakes. Return below the top station (at the lift support) to the starting point.
