“Shower naked.” That’s the mantra at Icelandic thermal pools. They are serious about keeping them clean! None of this rinse-off-in-the-shower-with-your-suit-on-before-you-get-in-the-pool stuff. We’ve been hitting ’em since Day One, when we hit two in Reykjavik. The first was a neighborhood pool with a medium-sized slide (closed, unfortunately), a waterfall, a floating hot dog to play on and three hot tubs with gradually increasing temperatures. But then we hit the BEST one: Laugardalslaug. HUGE! Eighty-three meter enclosed disco slide that goes from open to black (eek!) to disco lighting!
