A dwindling budget and long summer queues meant I didn't get to go inside, which I was a little disappointed by at the time. However the outside was impressive anyway, and at the start of summer the flowers were in bloom and the fountains all cascading. This made for a really rewarding walk around the grounds. I really enjoyed the ramble up-to, and view from the Colonnade, as it enabled me to see the lay out of the grounds and provided a nice view over Vienna. This site is worth the short trip out from central Vienna, even if you don't want to pay to see the interior.
