You can just roam around the whole place though it’s quiet big. Parking fee is 7 euro for the whole day. Per person costs 2.95 euro each.
It’s so nice here. You will surely have peace of mind.
There are kiosks around that sells foods and drinks, however, I recommend if you just bring your own snacks because I think it will cost you an extra amount if you’ll buy the goods inside. I forgot to bring with me water, so I had one from them which costs 2.50 euro and to imagine it was just 500ml.
How great it is to witness such beautiful creation from above.
