On a budget, weigh it — A'DAM Lookout isn't cheap for what it is.
€16.50 deck; swing ~€6.50 extra
The best wide-angle view of the city and a genuine adrenaline hit if you brave the swing dangling over the building's edge. The catch: it's a short free ferry plus a steep ticket for the view, and on a grey day the panorama is just flat grey rooftops.
