If you are driving, the most direct route from Vienna is via the Semmering mountain pass through Styria to Graz and on to Klagenfurt. Or take the heavily traveled A2 from Vienna to Graz and farther south. From Salzburg, the A10 autobahn tunnels beneath the Tauern range and the Katschberghöhe to make a dramatic entry into Carinthia, although the parallel Route 99, which runs "over the top," is the more scenic route. A pretty alternative here that leads you straight into the Nock Mountains or Gurk Valley is to leave the A10 at St. Michael after the Tauern Tunnel, head toward Tamsweg, and then take Route 97 through the Mur Valley; at Predlitz the pass road begins its climb over the steep Turracherhöhe into the Nock Mountains. The fork to Flattnitz, the most scenic way into the Gurk Valley, is at Stadl. Several mountain roads cross over from Italy, but the most traveled is Route 83 from Tarvisio.
