Oh nice you have been to trebon, It is a place not so far away from my home (Linz Austria) and there should be one of the biggest White Tailed Eagle populations in the Middle of Europe. I really need to visit it soon, but at the moment I don't want to get over the border because of the Covid Restrictions. Maybe in Summer there will be an opportunity to easily visit it. We will see.
I think by car it is available even for one day trip.
That is true, about 2 hours with the car but because of the Covid Restriction I don't know how strict they will be at the border.
There is nothing to see now and in the spring/summer it will be other.
