Driving on this road means visiting 2 TWHS at once, as this road runs north-south in the middle of Höhe Taurn National Park, which is another TWHS. 

I took a bus tour on this road from Zell am See to Kaiser-Franz-Josefs-Höhe, which is the centerpiece of this TWHS, for 34 Euros with a company called Blaguss. The entrance fee to the National Park itself is 36 Euros per car, so it's a good deal. There is no public transportation from the north end of this road to Kaiser-Firanz-Josefs-Höhe at this time. 

I was told that due to the abundance of snow on the road, this road did not open until late May this year whereas it usually opens in early May.  But while they were clearing the snow on the road, it seemed like a lot of snow has melted on the mountains, exposing some ugly traces of avalanches. 

The Kaiser-Franz-Josefs-Höhe area is fully ready for tourists with an info office, one glass-caged viewing platform, and at least 3 restaurants, 2 of which were open.  That should be the case, as the OUV of this site is supposed to be its status as a prototype of mountain roads created for tourism. 

The tour was led by a ranger from the National Park, who was quite informative but tended to go too much into detail, cutting into our lunch hours.

This road reminded me of Highway 93 that connects Banff NP and Jasper NP in the Canadian Rocky Mountain Parks WHS.  Both offer spectacular views of mostly snow-capped mountains. The difference is that Highway 93 runs straight while this one decidedly meanders. 

But I do have to say that the scenery I've seen from the nearby Kitsbuhel ski area beats anything I saw on this day.

Another way to approach Kaiser-Franz-Josefs-Höhe is from Lienz on the south end of this road. I have never been to Lienz, which is supposed to anther city in Austria surrounded by spectacular mountains.  I later learned that these was a public bus connection from Lienz through Heiligenblut to Kaiser-Franz-Josefs-Höhe in summer, so if you come from Italy to Lienz, this may be a good option.
