One of the hippest neighborhoods in the city is Amsterdam-Noord, situated directly across the IJ River from the main train station. Here, an iconic 1970s office high-rise has been recently revamped and rebranded as A’DAM, an acronym for Amsterdam Dance and Music. Along with music-themed businesses, restaurants, and an underground nightclub, the tower boasts the rooftop Lookout, an open-air observation deck 20 stories up that offers panoramic views of the historic city center, the bustling port to the west, and the Dutch landscape beyond. Daredevils line up for Over the Edge, a huge metal contraption that lets you literally swing out over the edge of the building. Entrance to the Lookout is €12.50 (about $15) and a ride on the swing is €5 (about $6).
