Saut du Day is a dramatic Swiss waterfall on the Vallee de Joux–Vallorbe side, spilling over a rocky ledge into a narrow gorge. It offers fast-moving water textures, misty atmosphere, and classic viewpoints along the trail network. Best in spring–early autumn when flow is strong; dawn/late afternoon brings softer light and lower crowds. Accessible by car to Vallorbe, then short local walking paths—no special entry fees reported, but check seasonal access signs.
