Of course drivng through a woodsy area is nicer than using expressways, but whether it is worth doing is up to you.
Be also aware that E-59 is not a national road number, it just an additional designator for an European corridor.
Google Maps usually determines the fastest route.
Obviously the fastest way is the motorway which cuts through the woods, but the minor roads are more scenic. I presume you mean Heiligenkreuz abbey?
Yes, I plan to leave Greifenstein in the morning, visiting Cistercian Abbey Stift Heiligenkreuz before noon, then continue driving eastbound and visit the Schonbrunn Zoo in the afternoon. For the morning portion, Google gives 3 options (1) via Motorway along Danube then westbound on A21, 54min/58KM, (2) via Vienna Woods and eastbound on A21, 60min/68KM, and (3) via B19 and A21, 61min/66KM. I plan to take the second option because it might be more scenic and relaxing. I am seeking your comment on this choice, and appreciate it very much if you would advise on any point I should stop. Below is the three paths identified by Google. Thank you.
Thank you. I will follow your advice via Breitenfurt. This is the shortest distance, 65min/49KM.
I just realized that you could alternatively visit the abbey in Klosterneuburg, which would not force you to drive such a large detour, even if the drive was somehow worthwhile.
Thank you for the advice. If we have time we would include the abbey in Klosterneuburg. Driving through the Vienna is a dream event for me. I look forward to the pleasant drive via Breitenfurt. Thank you again.
I hope that you won't be disappointed because I do not think that the views will be that breathtaking, it will just be a nice drive.
