If you are visiting the Morteratsch Glacier, then make sure to check out the Cascada da Bernina waterfalls, which are right near the parking.

You can see some of the falls as you cross the bridge from the parking to the glacier trail. But for the full experience, follow the trail up along the roaring river to a series of viewpoints over different sections of the falls. The water levels might be a little lower in fall. But the golden larch trees should make up for that.

See hiking map for Bernina falls.
