1 Best Sight in Carinthia and Graz, Austria

On the shore of the Wörthersee, a winding 5-km (3-mile) road ascends to the 2,790-foot observation tower, the Pyramidenkogel; take its elevator (or the climb 441 steps) up to its three platforms and you can see out over half of Carinthia. The quickest way down is via the slide (separate ticket required) which promises to have you at ground level within 18 seconds.
