Intro

10,000 years ago, 100 billion cubic metres of rock thundered into the valley. Known as the Flims Rockslide, this event created the Ruinaulta, a canyon-like gorge in the Anterior Rhine Valley that can be reached on foot, over water, by train or by bike.

The Rhaeto-Romanic speaking inhabitants of the Vorderrhein ravine call it Ruinaulta, a word meaning high heap of rubble. And indeed, the bizarre whitish rock formations consist of debris from a prehistoric rockslide that blocked the Rhine near Flims after the retreat of the Ice Age valley glacier.

Since then the river has eaten its way through the rubble, forming an impressive gorge. The Rhaetian Railway runs through the canyon, where adventurers enjoy river rafting and observers make their way to the “il Spir” viewing platform.

What has come into being is a natural, magical place full of mysterious lakes in the Mountain Forest, rare orchids and breeding grounds for endangered species of birds. Further below, gently sloping sand banks alternate with wild rapids and make the region of the Rhine gorge an adventure for hikers, bikers, rafters, canoers, nature lovers and explorers alike.
