• Posted for ages 6 to 16, so younger siblings are better off in the sand by the water channels
• No sliding when wet: the park asks families to keep off the slides in and after rain
• Nearest gate is Vía Pecuaria Sur in Las Cárcavas, at the Glorieta de Isidro González Velázquez

On a hillside in Parque Forestal de Valdebebas, three long metal slides zigzag down between planted slopes. Kids climb back up by a red rope net, ropes and a row of wooden stumps, then go again. A 50 m double zip line faces the slides, and nearby water play has Archimedes screws, water wheels and gated channels to redirect, with sand for smaller kids.
