We saw the falls at pretty high flow during our trip, but I've read that its flow diminishes significantly late in the Summer since it's sourced by melting snow.

From the car park (see directions below), we walked towards the stream where a path followed it downhill. As we descended along the stream, we got views of parts of the cascades as they rushed towards the main part of the falls. And after a few more minutes of walking, we reached a small lookout area with a view of the main section though it was hard to photograph it from here.

Beyond this overlook, we continued to descend along the path as it briefly went away from the stream through some vegetation before returning towards the stream at the base of the falls. It was at this spot that we got our most satisfactory views though it was a bit misty down here.

All in all, it took us no more than 10 minutes each way to do the walk.

Directions: Rovijokfossen is right off the E8 about half way between Skibotn and the Finland border (roughly 18km from Skibotn). It was pretty easy to miss the car park for the falls (as we managed to do before doubling back) as the E8 moved pretty fast and the sign for the car park was hard to read from the road.

To help with finding the car park, it's worth mentioning that there was a bridge on the E8 going over the watercourse responsible for the falls. If you cross that bridge, you went too far.
