Stag Water Park in Madrid

Madrid Water Park is undoubtedly the cool spot to hangout in the sweltering Madrid summer. Here the cool breeze from the mountains makes it an ideal spot to get away from the stifling summer heat in the city.

Try the Kamikaze water slide if you've got a head for heights and suicidal jumps, or maybe hurtle down the Black Hole, a rather fearsome toboggan that'll have you sliding and gyrating through its slippy bends. Or there's the adventure pool, the wave machine, and quite a few more.

Or if simple people-watching is your bag, just disembark from your rubber dingy, pull down your shades, and watch the world go by with an ice-cold beer in one of the secluded bars.
