The falls themselves are about 3.7km along a mostly-paved trail, though the last kilometer is just dirt, ending in about 300 stone steps that can get quite steep at times. There's also a tricky section just before the end of the first kilometre where the path gets very steep, but it only lasts a couple of hundred metres and after that it's pretty flat until the steps. And there's a sala to sit and rest, or just take in the scenery, every kilometer or so.
