Multiplex Terrace Wave is CityWave's indoor standing wave built into the SCS Shopping City Süd mall in Wiener Neudorf, just south of Vienna. The wave adjusts from about 1.1 to 1.4 meters and runs wide enough to actually carve on, with sessions split into beginner, advanced, and trick levels so it works for a first-timer or someone chasing airs. There's a Blue Tomato shop right next door if you need a board or wetsuit, plus parking and the rest of the mall's amenities on hand. Expect a per-session fee and a steady audience of shoppers-turned-spectators watching through the glass.
