Saut du Day, Waterfall at Vallorbe, Switzerland.
Saut du Day is a waterfall near Vallorbe where water plunges down moss-covered rocks surrounded by forest. The falls drop directly beneath a large railway viaduct that spans across the Orbe valley.
The viaduct above the waterfall was completed in 1925 and connects Cossonay to Vallorbe as a key railway line. The structure used stone from nearby quarries and represents early 20th-century engineering.
Local fishing traditions continue at the Orbe River, where visitors catch trout and bring them to nearby restaurants for preparation.
The site is best reached by train to Day station or by parking nearby and following the local hiking route to the waterfall. The path goes through forest with some elevation changes, so sturdy footwear is needed.
Below the waterfall lies an old tunnel system that once channeled water to turbines for electricity generation. These remnants of early hydropower show how people harnessed the force of falling water.

The Haute-Savoie is home to waterfalls with very different characters. Some are hidden along forest paths, like the Cascade du Dard near Chamonix, while others tumble down from tall limestone cliffs over hundreds of meters. The Cascade d'Arpenaz near Sallanches is one of the tallest in France, with an 860-meter drop. The Cascades d'Angon flow down in several steps to Lake Annecy, and the Cascade de la Diosaz can be visited through walkways built in a gorge. The Cirque du Fer-à-Cheval contains around thirty waterfalls that flow along a rocky amphitheater. Depending on the season and snowmelt, the flow changes, altering the atmosphere of the place. Other waterfalls, like the one in Nyon accessible by cable car or the one in Seythenex with its old water wheel, offer easy walks suitable for everyone.
