This marvelous geographic formation of lake elevation cliff is made of fluvial erosion, in singular white marble. Find time to visit this natural sanctuary into which the water has carved incredible cathedral like formations. As your boat carries you on a breathtaking tour, you will be astounded by the sheer scale, colour and texture of the marble tunnels which seemingly float above the clear water of lake, reflecting filtered light. It is without a doubt a stunning, picture-perfect Patagonian moment.
