THE HARDEST BIKE CLIMB IN AUSTRIA
This is the hardest bike climb in Austria, but the upper portion may be closed to bikes as of June 2018, we would recommend to double check Strava before traveling long distance for this climb. With that caveat, here is our report: At 9.7 miles with an average grade of 10.6% and Fiets Index of 18.39, this is the most difficult climb in Austria and a World Top 10. The climb is very scenic and ends at an aircraft detection radar tower. Grosser means “great” in German and this truly is a great climb!
THE NEXT HARDEST BIKE CLIMB IN AUSTRIA
Don’t blink or you’ll miss this one! At km 2.9/mile 1.8 there’s a right turn onto a one lane access road to Oscheniksee Reservoir that is 9.33 km (at 12.6% average grade!) up the hill and through multiple sets of wonderful hairpins.
This is an access road no doubt for service vehicles to the reservoir and dam. We have never heard of anyone having an issue riding a bike on this road.
HIGHEST BIKE CLIMB IN AUSTRIA
This is an amazing climb that has many features to it -- Rettenbachferner is not just another pretty face! First, this is a Top 50 World Climb and simply a brute! At just over eight miles it averages a 10.7% grade and has a mile 2.5 mile stretch averaging just over 12%! So, it really tests us from start to finish and is well worth the trip to Solden just for the challenge of the climb itself.
This is the highest paved road in Europe that is open to motor vehicles. Pico Veleta is a higher road, but it is not open to motor vehicles all the way to the top.
BEST ROAD IN AUSTRIA
Grobglockner is the highest mountain in Austria and the road over it is an engineering marvel. The road surface is impeccable, with many stunning views of the surrounding mountains along the way. The climb is very challenging, averaging nearly 9% over 11.5 miles. Grobglockner from the Fusch (north) side is ranked #28 on our Top 100 World Climbs List (from Pockhorn it is ranked #86).
The grade is nearly constant throughout the climb -- the average for steepest ¼ mile is 11.67, steepest mile 10.76 and steepest stretch over a 2.5 mile run is 10.1%. Other than a respite through the hairpins (Kehres), there is no relief from the double digit grade.
