From Hilton Skybar, you can view the entire landscape of Venice.

Giudecca Island in Venice is definitely worth a visit. There's actually a Hilton hotel there, and on top of the hotel, there's a Skybar. If you have time, go to the Skybar for a drink. The view from there is amazing. You can see the entire island of Venice from above, with its orange-red tiled roofs and the whole Venice lagoon. There's really no other place where you can get such a view. Highly recommended.
