Gjerdefossen is probably the first named waterfall you'll see on a Geiranger Fjord (Geirangerfjorden) cruise. This waterfall is also accessible by a trail that leaves the Eagle's Road (Orneveien) section of the Rv63 and leads to a profile view of the falls overlooking the scenic fjord. However, the flow of this waterfall seems a bit limited (at least compared to some of the other named as well as unnamed falls in the fjord) so I'd imagine this one dries up as the summer progresses.
