There are several paths to get to the top of the leap, most of them are marked with pink and blue markers. You generally follow the river up until you can see a path splitting up to the right.
Here you can go straight to the waterfall, or you can go right up the path. The path to the right is a lot easier walk than the waterfall.
The terain is quite difficult at times, but the view is worth it.
Bring lots of water.
Congratulations to Frullet with the FTF!!
