The River Dochart doesn't so much fall as tumble. It's a broad series of rapids that spreads across slabs of rock and pours under the Bridge of Dochart, first built in 1760, right at the west end of the village. After heavy rain the whole thing roars, and the view from the bridge is the picture everyone takes away from Killin.
Just below the falls, a small bridge leads to Inchbuie, the "yellow island". The walled MacNab burial ground is in the trees there, and you can see it from the bridge. There are flat rocks to sit on beside the water, though they're slippery when wet.
