This waterfall is a 3-4 minute drive from Skogafoss!
A short, relatively easy 20-minute walk from the Skógar Museum will lead you to the stunning Kvernufoss. It's much more quiet here as tour buses do not stop here. During the summer, you might be treated to a sight of some sheep! You will need to use the Parka app to pay for parking.
Make sure you stay on the trail to follow Leave No Trace ethics :)
