The spectacular Rhine Falls at Laufen-Uhwiesen , Switzerland are example which establish the supremacy of the mother Nature as far as creation is concerned.
Beautiful is way too small a word to define the whole environment around the falls. And the best part is , they take you right near the falls where you can actually touch & feel the flow from a marginal distance. There are of course different packages for the boat ride with different cost , depending upon how close & how long you wanna enjoy the ride.
Whichever package you choose, just don't miss the permanent Rainbow formations in the vicinity of the waterfall.
