Steall falls (also named An Steall Ban, Steall Waterfall) is an impressive waterfall where the river Allt Coire a’ Mhail plunges down from Coire Dubb an Stell over 120 meters.
Steall falls can be found near Achriabhach/Glen Nevis, south of Fort Williams in Scotland (United Kingdom). Driving on the A82 at Fort Williams go south to Achriabhach/Glen Nevis. Here you can find a parking and I don’t think it is possible to drive further on, although there is a parking further up the road.
There is a trail going east following the river Nevis. After a sharp curve there is a bridge. From here you already can see Steall falls. I think the trip takes 60 minutes (4 kilometers)
