FATMAP difficulty grade
The Zillertal High Road has five different access points in total.
The southernmost begins in Hippach (between Mayrhofen and Zell am Ziller), the northernmost in Ried, only ten kilometres after the mouth of the Zillertal Valley.
It makes no difference which access point is used by road bikers, as the five ascents are all more or less equally steep and long.
The highest point at 2,010 metres can be reached via the southernmost route shown here. If you think you have made it once you reach the top, you are sorely mistaken.
The High Road is by no means flat: the highest point at the end of the southernmost ascent is around 2,010 metres above sea level next to the Melchboden snack bar.
If you stay on the High Road, it leads back downhill to an intersection with the access road from Aschau at around 1,460 metres.
The road then leads uphill again and takes you an altitude of around 1,900 metres and the ski area of Hochzillertal, where you can also stop at various restaurants to enjoy welcome refreshments.
From Kaltenbach Ski Lodge, the route then leads downhill to the toll booth and splits into two roads down to Kaltenbach and Ried. Tip! The access road from Ried is least busy during the summer months, meaning you are virtually alone on the road as a cyclist.
