The Grossglockner High Alpine Road – or Großglockner-Hochalpenstraße – is named after Austria’s highest mountain (3,798 m).
For cyclists, the road doesn’t get up that high, but the cobblestone (side-)road up to the “Edelweißspitze” reaches a respectable 2,571 meters.
(I noticed the map above reads 2,572 m, but both in 2009 and 2017, the “official” summit sign read 2,571 m, as also mentioned on most other info pages.)
Since this side-road – starting at 2,394 m from Fusher Törl – is a dead-end, the ‘official’ pass height is at the Hochtor (2,504 m) making it the highest pass in Austria, ranked 7th in Europe.
The Grossglockner features (annually) in the Tour of Austria and was also visited by the Giro d’Italia twice (1971 and 2011).
The Grossglockner’s most popular stretches are:
- The timed “King of the Glockner Route” from Ferleiten (1,145 m) to the Fuscher Törl – 2,428 m: 1,283 m elevation over 12.9 kilometers (took me no less than 1:19:51)
- A side trip off the Fuscher Törl to the Edelweißspitze – 2,571 m: an additional 177 m of elevation over 1.8 kilometers
- The south ascend from Heiligenblut (1,300 m) to the Hochtor – 2,504 m: 1,234 m of elevation over 15.1 kilometers
- The side trip to Kaiser Franz-Josef-höhe – 2,369 m: 508 m of elevation over 8.5 km.
In 2009, I cycled up the Grossglockner Hochalpenstrasse from Bruck, including the Edelweißspitze and the KFJ-höhe – report on that trip here.
I revisited the Grossglockner in 2017, after I participated in the Marmotte Hochkönig two days before.
I planned on tackling both ends in one ride – skipping at least the fork up to the KFJ-höhe – but I was unable to complete that mission, due to fatigue and hot weather.
So I settled for a round trip from Bruck to the Hochtor, with the Edelweissspitze on the return – report of that trip here.
Grossglockner from Bruck / Ferleiten
It’s 21.4 kilometers long up to the Edelweißspitze and 26.3 kilometers to the Hochtor – if you decide to include the Edelweißspitze, you will have covered 29.5 kilometers.
The total from Ferleiten to the Edelweißspitze is some 14.2 km with around 1,385 m of elevation – that’s a hefty 9.8% average…
The toughest part is also the part with the more spectacular views, which will take your mind of the physical challenge a bit. Also the view down from (near) the Fusher Törl is quite spectacular.
If you have paid the fee for a ticket that will earn you a ‘certificate’ when you get back down to the Ferleiten toll station 1, you will have to stamp that at the Fuscher Törl memorial, just past the Edelweißspitze split.
The cobblestone road to the Edelweißspitze was actually constructed with money that was left over after the (main) road was completed. At 10% it’s not easy to climb, but this short series of hairpins is even harder to descend…
Just past the Fusher Törl, there’s a restaurant and souvenir shop, with quite a view, as seen in the picture below.
Cycling on, you’ll descend for about two kilometers (166 altimeters) to Fuscher Lacke, after which you’ll climb the remaining 4 kilometers (241 altimeters) to the Hochtor, which is a 310 m long – and pitch dark – tunnel crossing the Alpine Divide – there’s a kiosk at the Carinthian side of it.
The total elevation gain over this route, including the detour up and down Edelweißspitze, is 2,041 m (6.9% over the 29.5 km, or 7.9% over 25.7 km without descends).
Despite this almost moderate average, I have put this climb in my personal top 3 of hardest climbs in the Alps.
Although it’s ranked “only” 12th in the list of toughest climbs, it’s positioned 3 places higher than the Zoncolan on that same list…
1 You just pay for the ticket to time your effort – you do not pay toll when on your bike; only motorized traffic pays toll.
Grossglockner from Pockhorn / Heiligenblut
However, that 3 kilometer prelude at 6.6% average is not as friendly as the one on the other side; from Pockhorn, the climb is some 17.5 km, with an altimeter gain of 1,374 meters.
Note that the profile card starts even further out, in Reintal; if you include that stretch to Pockhorn as a warm up, you’ll cover 21 km more, but with only 250 more altimeters.
From Pockhorn to the Edelweißspitze, the total elevation gain is 1,814 m or an average of 9.4% over 19.2 km.
Which is almost as bad as the ascend from Ferleiten, maybe even worse, as it is 5 km longer…
From this end, upon reaching the Hochtor, you’ll pass through the tunnel and descend some 4 kilometers (241 m elevation loss) towards Fuscher Lacke, after which the 2 kilometer climb (166 m elevation gain) will bring you to the Fusher Törl.
You can use the momentum of the short descend to start the Edelweißspitze climb, but you’ll have to shift gears pretty quickly, to get up those 1.8 kilometers at 10%…
Grossglockner – Kaiser Franz Josef-höhe
This dead end starts at the roundabout Guttal – in the flat (> Hochtor) zone in the profile picture to the left – and is some 8.5 kilometers long.
With an elevation gain of 508 m (6%) it may not seem that challenging, but enjoying a biting cold wind accompanied by equally cold showers, it left me gasping for breath nonetheless.
The scenery along this stretch is as overwhelming as the rest of the Grossglockner; the picture below is actually showing the road up to ‘the höhe’, as viewed from the Margaritzenstausee.
