Fantastic scenery. Not as monumental as Niagara falls (Krimmler is the 5th highest waterfall in the World while the highest one in Europe) but much more picturesque. We spent a day there but it was hardly enough. You may enjoy a day there even with small infants, as the area is well developed. A concrete path leads up to the top of the falls, passable with baby carriages. The road to the top is 4 km. The height of the falls: Bottom one: 140 m middle one: 100 m, top one 140 m.
