The cascade of Gerber is clearly visible from the road that crosses the Port of Bonaigua. The arrangement of the old road that used the Port of Bonaigua carriers and building a viewpoint allows us to easily get closer to the very foot of the waterfall that falls from the Gerber hanging valley. During the last ice age, 40,000 years ago, the glacier descending to the main valley excavated the rock bed much more sharply than in the neighboring valley of Gerber. This explains the existence of this jump.
