I have recently been touring skyrim and trying out all the water slides to see which is the best one. You just pick a good fast flowing river with plenty of big drops along the way and just jump in the river and get swept along the river and over the water falls. the really big waterfalls are also a lot of fun and you never get killed by the massive drops. so has anytime else tried doing this yet in the game?

yes i have, but outside of the reach iv found that a lot will kill you on the way down though

Splash Mountain. It's in Hjallmarch, right next to Knot's Berry Farm.
