Since we wanted to do some hiking in the area but also wanted to start a bit higher up already, we drove up the Zillertaler Höhenstraße. Can definitely recommend it. For someone who has been driving on such alpine roads it's not too challenging (I've experienced way harder ones and this one is quite well built and partially even spacy), for beginners I can see how it's not so easy though; still doable and nothing to be afraid of. Once you are up there, you find plenty of parking spaces and options for things to do. There are plenty of restaurants, entertainment for kids as well as hiking routes of different length and difficulty.

To enter the official hohestrasse you have to pay 8 euro. The road before the official hohestrasse was already very small and tricky on some parts of you are not used to it (we entered from the north site). The hohestrasse itself was a little better and had more spots to pass upcoming traffic. It has some spectacular views on the valley of zillertaler. There are also several spots were you can drink and eat something. Make sure you keep following the signs because sometimes there are several turns which lead back to the valley and you miss parts of the hohestrasse. On the most south part the road becomes larger and there are even busses that drive up to a certain point. Useful for backpackers. It was a nice experience and worthwhile if you are in the vicinity but it was not the most beautiful alpenstrasse we have driven. The road could also use some maintenance on some parts
