Luckily no regulation affects Aldeyjarfoss, as it plunges 20m (19.7 to be exact) over the columnar cliffs, and violently stirs up the big deep pool underneath.
Not tempting to slip into this tub! But nonetheless the former world record for a kayak drop was done here, as the Englishman Shaun Baker did that stunt in 1996.
The record today is very recent, set July 27th 2009, when Tyler Bradt executed a world record drop over the 55m Palouse falls in Washington, US.
